First things first: Thanks for stopping by.

I wrote the first Jigsaw Jones book in 1997 which — hold on, let me do the math — feels like a hundred years ago, or yesterday, depending on my mood. Time has that way of expanding or compressing. For the best way to access deep info about Jigsaw Jones — including lots of insider insights — I encourage you to click on “Jigsaw Jones” under CATEGORIES in the right-hand column of the main page. It will link you up to all sorts of choice tidbits. Otherwise, I intend to slowly, slowly build up this page with informal book-by-book descriptions.


A lot of exciting things are happening with this series, with a new book out in August of 2017, The Case from Outer Space. In addition, eight “classic” titles are now back in print, revised and updated: The Case of the Mummy Mystery, The Case of the Bicycle Bandit, The Case of the Smelly Sneaker (formerly titled, “Sneaker Sneak”), and The Case of the Glow-in-the-Dark Ghost, The Case of the Million-Dollar Mystery, The Case of the Buried Treasure, The Case of the Best Pet Ever, and The Case of the Disappearing Dinosaur. I am thrilled to see these books newly available, published by Macmillan (not Scholastic).

When Joey and Danika find a mysterious note tucked inside a Little Free Library book, all signs point to a visitor . . . from outer space. Yikes! Jigsaw Jones, America’s funniest kid detective, is back on the case, ready to inspire a new generation of young readers. From a Booklist review: “Fortunately, it is the sort of mystery that will please Jigsaw Jones fans, who know they can count on the series for likable characters and a bit of a challenge here and there. For example, when Mila passes an encoded note to Jigsaw, he explains the substitution cipher she used, and then lets readers decode it on their own. With short sentences, bits of humor, and engaging illustrations, the latest early chapter book in Preller’s long-running Jigsaw Jones Mystery series has plenty of appeal for young independent readers.”



I love how this book turned out, but it was sooo hard for me to write. At the time, I was still idealistic about how books were made, and I struggled against the necessity of having a cover before the manuscript was written. The whole mummy concept was sort of thrown at me, and it took a long time for me to figure out how a mummy could possibly fit into the story. In retrospect, I think writing this book made me grow up a little bit. An aside: When I wrote this book, my local elementary featured an annual Halloween parade, with all the kids circling the building. The book also includes a favorite song from my childhood: “Nobody likes me/Everybody hates me/Guess I’ll go eat worms./First you peel the skin off/Then you chew the guts up/Ooey-gooey wooorms!



Someone stole Ralphie Jordan’s rusty old bicycle. Jigsaw and Mila hit the trail to track down the thief. But one piece of the puzzle doesn’t fit. Who would take a hand-me-down bike? Solving this case is an uphill ride for ace detectives Jigsaw and Mila. To learn more “stories behind this story,” click here.



Jigsaw’s school is haunted! Some kids saw a ghost dancing in the classroom. There are footprints on the floor . . . and they glow in the dark. But ghosts don’t have feet, do they? Jigsaw Jones is not afraid. He will catch this glowing ghost even if he has to stay after school to do it.



Time out! The girls take on the boys in the biggest football game ever. But when one boy’s sneakers disappear, the players stop the clock. And Jigsaw and Mila take the field. It’s a tough case to tackle, but this detective team plays to win. Note: Retitled, used to be call “The Case of the Sneaker Sneak.” To learn more “stories behind this story,” click here.


Now you see it, now you don’t! Danika is doing a magic act at Bigs’s birthday party. For her biggest trick, she makes Bigs’s favorite toy disappear. POOF — it’s gone! But where did it go? Even Danika doesn’t know. Time for Jigsaw and Mila to use their own tricks to fix this mixed-up magic.


Show him the money! Jigsaw’s class is learning about invention, and Eddie Becker thinks he has a million-dollar idea. Too bad someone stole his Top Secret plan! Now Jigsaw has to invent a super-spy gadget of his own to this this funny-money mystery.


What’s bright and shiny and hard to find? Buried treasure! Jigsaw’s class finds a hidden riddle that leads them on a wild treasure hunt. Have pirates stashed their loot in Jigsaw’s school? The class hopes to become rich, rich, rich! But they’ll need an act detective team like Jigsaw and Mila to dig up the truth.


The prize for the pet show is missing. But Jigsaw has an idea that will help solve the case. He’ll enter the contest with his dog, Rags. Can Jigsaw and Rags make the town safe for dogs, cats, and goldfish everywhere? Or will they end up in the doghouse?



There are five more Jigsaw Jones scheduled for release, coming in the summer of 2019. The first is a brand new title, The Case of the Hat Burglar

Featuring illustrations throughout by R.W. Alley!

In addition, four classroom classics will be revised and updated for a new generation of readers: The Case of the Bear Scare, The Case of the Golden Key, The Case of the Haunted Scarecrow, and The Case of the Vanishing Painting.

Creepy attics, cobwebs, creaky floors . . . top detective Jigsaw Jones has seen it all. So when the new boy in town finds an old key hidden in his house, Jigsaw is ready to solve the mystery. But the clues are stacked against him. Will the key lead Jigsaw and Mila to their creepiest case yet?

Poof goes the painting! Jigsaw’s class is getting ready for Parents’ Night. They are painting pictures to show their families. One minute they are coloring. The next minute Geetha’s painting has mysteriously vanished! Red, blue, yellow, green. Can Jigsaw discover what the colorful clues really mean?

When Jigsaw takes a new case, he becomes the key witness. But he can’t believe his eyes. Scarecrows don’t walk, do they? It’s a case of private eye turned eyewitness. And it’s got Jigsaw and Mila scared silly. To learn more “stories behind this story,” click here.

The clues may tell a different story. Jigsaw and Mila will get to the bottom of this grizzly case. For more background info, click here.


I am very, very happy about this — and eager to visit your school!




The Case of Hermie the Missing Hamster

The first book in the series, so of course it holds a special place for me. When I started, Jigsaw’s working name was “Otis” and there was no sign of his partner, Mila Yeh. She didn’t appear until the second draft. In this story, Wingnut O’Brien’s hamster is missing — and the #1 suspect is a pet boa constrictor! You don’t need to read this series in order, but Hermie is a great place to start.


The Case of the Christmas Snowman

To write this book, I had to learn about numismatism. In other words, coin collecting. I also had to research Diwali, an Indian holiday. In this story, Lucy Hiller is in trouble. She gave her father’s rare coin — a 1937D Indian-headed nickel — to Bigs Maloney. He happened to be the biggest, roughest, toughest kid in the second grade. But the coin is missing and Jigsaw and Mila have to track it down. Or else they’ll be in trouble. Bigs trouble.


The Case of the Secret Valentine

In this story, someone sent Jigsaw a secret Valentine — yeesh! This case depends on an old mystery writer’s trick: gender assumption. As Jigsaw says early in the case, “You know what the worst part is. This girl is ruining a perfectly good holiday. I mean, I like Valentine’s Day. You get to eat cupcakes. Why does she have to drag love into it?” There’s also a little bit of info about Abraham Lincoln thrown into the book, just because!


The Case of the Spooky Sleepover

“Ghosts?” I repeated. “Like Casper the Friendly?” Ralphie Jordan shook his head. “No, the unfriendly kind.” And now the only way to crack the case is for Jigsaw to spend the night in Ralphie’s haunted house. There’s a lot of creepy fun in this one, with squishy eyeballs and flying popcorn. I always liked the way this book begins, establishing character: Ralphie Jordan was the most popular kid in room 201. Everybody liked Ralphie. And Ralphie liked everybody right back. He had dark eyes, dark skin, dark hair — and he was as thin as a flagpole. Best of all, Ralphie Jordan was a world-champion smiler. Nobody had a bigger smile or used it more often. Only today, Ralphie wasn’t smiling.


The Case of the Stolen Baseball Cards

Things you should know about this book: 1) It begins with some lines lifted from a Beatles song, “A Day In the Life,” as a sort of tribute to some musical heroes; 2) Ms. Gleason’s dog, as described on p. 12, is really my old dog, the dear departed Seamus; 3) as a kid, I totally used to dress up and wrestle like Bigs Maloney; 4) I have a complete set of 1969 Topps baseball cards — a cherished possession; 5) I dedicated this book to author Raymond Chandler, whose great books helped inspire this series; 6) I wrote the first draft of this book in November, 1998


The Case of the Runaway Dog

There’s a lot to talk about with this book. It was partly inspired by my runaway turtle, Green Fingernail. That’s right: Green Fingernail, wiseguy. There’s an old man in the book, Mr. Signorelli, who becomes not only a key witness, but a friend to Jigsaw. Like my own mother and father, he smoked. My editor, Helen Perelman, wanted me to take that out. But I insisted. Just because he smoked, it didn’t make him a bad person. Toward the end of the book, Jigsaw realizes that the old man will be alone on Thanksgiving. I like that moment immediately after Jigsaw asks him about his Thanksgiving Day plans: He scratched the end of his nose and looked out across the lake. I followed his gaze. But there was nothing there. Just water and emptiness. To learn more “stories behind this story,” click here.


The Case of the Great Sled Race

One of the things I try to do in each book, mostly just for myself, is to make a reference to a real book. It’s just a subtle way of connecting Jigsaw’s fictional world with the reader’s everyday world. I was more ambitious here, with Ms. Gleason reading Stone Fox by John Reynolds Gardiner in the classroom. She even introduces the idea of The Five “W” Questions essential to reading and writing: who, what, where, when, why. As Jigsaw realizes: “Reading was like detective work. Figure out the W questions . . . and you’ll catch the crook.” Note: By way of tribute, I lifted, and transformed, the setup of this story from Raymond Chandler’s great book, Farewell, My Lovely. The character of second-grader Bigs Maloney is partly inspired by the hulking ex-con, Moose Malloy. To learn more “stories behind this story,” click here.


The Case of the Stinky Science Project

I hoped the word “stinky” would help rocket this book to the bestseller list, but no such luck. There’s not as much Science Fair material in this story as I had initially hoped. But I was able to introduce a new character, the redoubtable Sally-Ann Simms. Don’t be fooled by the lace socks and little red plastic pocketbook. Sally-Ann is a walking hurricane in lavender and pink. Unfortunately, Bobby Solofsky — Jigsaw’s arch nemesis — fools Sally-Ann (who is only four) with a phony magic trick and gets away with her weekly allowance. When Sally-Ann hires Jigsaw to make things right, he uses the Scientific Method to figure out the solution.


The Case of the Ghostwriter

A surprise author is coming to Ms. Gleason’s class. It’s a real mystery. Ms. Gleason won’t say the name of the writer. Some kids think it might be a ghostwriter — the secret author of the famous Creep Show series! The class hires Jigsaw and Mila to solve the case. Soon they are hot on the trail of the mystery author.

The Case of the Marshmallow Monster

Jigsaw is excited about a camping trip with his friends. No school. No detective work. But a full moon and a campfire story about a lake creature get Jigsaw back to business. Danika is sure a Marshmallow Monster is haunting the lake. Jigsaw and Mila scope out the area and wait to find out the real story of the Marshmallow Monster!

The Case of the Class Clown

Athena Lorenzo has been slimed! And she doesn’t think it’s funny. Someone in Ms. Gleason’s class is playing practical jokes. It’s up to Jigsaw and Mila to catch the clown. This could be their stickiest case yet! To learn more “stories behind this story,” click here. And for news about the touring musical, check this out.


The Case of the Detective in Disguise

Someone is stealing brownies from Mike and Mary’s sandwich shop. Jigsaw is piecing together the clues — one crumb at a time. But no one is gong to snatch a brownie with a detective watching. Time for Jigsaw to go undercover and catch the brownie bandit.


The Case of the Race Against Time

Jigsaw is in big-time trouble. For a dollar a day, Jigsaw and Mila make problems go away. But now Jigsaw has some trouble of his own. He lost his grandfather’s watch! Can Jigsaw and Mila find the watch before time runs out?


The Case of the Rainy Day Mystery

Big Maloney is acting fishy. He doesn’t want to stomp through puddles or make mud pies. Is Bigs up to no good? Or does he have the rainy day blues? Jigsaw Jones, super-spy, is on the case!


The Case of the Perfect Prank

Yikes! Jigsaw’s brothers love to play practical jokes. But Jigsaw does not have time for games. He has a big case to solve. Danika’s kitty has been cat-napped! Can Jigsaw and Mila solve the mystery? Or will the cat burglar have the last laugh?


The Case of the Double Trouble Detectives

Jigsaw Jones is the best detective around. Until his super-rich friend, Reginald Pinkerton Armitage III, decides to become a super spy. Reggie uses cool spy toys like night vision goggles to solve mysteries. But fancy toys don’t make the detective. Jigsaw is actually worried about his friend. After all, crime can be a rough business. And poor Reggie was about as tough as a pair of silk pajamas.


The Case of the Frog-Jumping Contest

RRRRRRib-bit! Jigsaw and his friend Stringbean are in a frog-jumping contest. The frog with the longest leap wins. It’s great until the champion frog disappears just 24 hours before the contest. Jigsaw is only a hop, skip, and a jump away from catching the frog-napper. To learn more “stories behind this story,” click here.


The Case of the Food Fight

When someone starts a food fight in the school cafeteria, everyone points a finger at Joey Pignattano, notorious milk-snorter and all-around gross-out. But Jigsaw knows Joey has a good heart. Joey would never throw food he could eat instead! Now Jigsaw has only twenty-four hours to clear Joey’s name before the evidence gets mopped up, Luckily, no case is too big — or too messy — for Jigsaw Jones and his partner Mila Yeh.

    I am a grade 2 teacher and my students are working on writing letters. One of my students loves your books and has written you a letter. I am wondering if you can provide me with an address so he can address an envelope and mail it out.

    Thank you kindly,

      Thanks for that note. That’s how I often think of the Jigsaw/Mila combo. He’s the one who makes mistakes, but has such a great never-give-up spirit. Mila is the smart one, and a loyal friend. Together they are unbeatable. Congratulations on your academic success. No matter who you are, there’s books that are just right for you in the library. It’s just a question of finding the right help in locating them. You might enjoy my “Scary Tales” series. The books are not too difficult to read, but the stories can still appeal (and scare!) older readers.

  15. Jessica Lehmann says:

    Silly question for you. My husband and I read your Jigsaw Jones books with our first grader. My husband and son read Mila’s name with a long /i/ and I read it with a long /e/ sound. Could you help our silly family debate by sharing how you intended it to be read?

    • jimmy says:

      Jessica, not a silly question at all. I hear her name a MY-LA, others hear it as ME-LA (Mila Kunis, famously). When I finally realized there was confusion out there, I was too deep into the series to do anything to counter the situation. Scholastic made a few audiobooks a while back, and I was bummed when even they got her name wrong. At this point, I’ve decided that it doesn’t matter, I’m just grateful to anyone for reading the books. Thank you!

    like ur books ALOT!!!!!!!!!!!!!

  17. Diane says:

    Is #1 available to the retail market?

    • jimmy says:

      Diane, The Case of Hermie the Missing Hamster is not currently available. Right now there are no plans that I am aware of to bring it back into print. Honestly, I think it all comes down to sales. Macmillan is making a big commitment this year to bring back 8 “classroom classics” and 1 brand new titles. At this point, the market will decide. My fingers are crossed.

  18. Laura Swanson says:

    I read the Jigsaw Jones series probably hundreds of times when I was in elementary school. This series was the foundation of who I wanted to be, so much so that all of my birthday & holiday presents moving forward were magnifying glasses, notebooks, and detective gear. I’m 22 now, and just graduated with my Master’s in Social Work. I work in criminal justice/victim services and solve mysteries of my own in regards to mental health & forensic psychology. I can’t help but believe my life would be different if my 7 year old self hadn’t had inspiration from Jigsaw Jones. Thank you for these books, they will always have a special place in my heart.

  19. Shivika Nayyar says:

    My 5 year old son was Jigsaw Jones for this Halloween. He handed out his business cards all over the neighborhood “for a $1 a day, make problems go away(plus expense)”
    Thank you for creating JJ.

    • jimmy says:

      Really? That’s so great. What an honor. He must have looked adorable. Good for him, and I’m sure thanks to you, to find inspiration from a book rather than the tv/video world.


  20. Mehul says:

    Why there are two Jigsaw Jones Series? What is the difference? My child loves the 1st series.

    • jimmy says:

      Great question. Jigsaw Jones was originally published by Scholastic. The first title dates back to 1998. Forty titles were published in the series — most numbered, except for 6 “super specials” and an activity-type book. Over time, the series began to fade in popularity, Scholastic stopped promoting it, and let it die on the vine. You could not find them in stores anymore. At which point, Macmillan stepped in and purchased the rights to 12 of the books. It was their intention to revise and update those twelve books; in addition, I wrote two all-new original books in the series (The Case from Outer Space; The Case of the Hat Burglar). Now there are 14 Jigsaw Jones titles available in stores and online, published by Macmillan, in a slight larger format. However, Macmillan decided NOT to number the books, because the titles their selected — for a variety of convenient reasons — did not come in order.

      To answer your question: There are not two series and really there’s no difference. The ones you can buy now are updated — for example, besides minor language tweaks, we got rid of all the land line references. Thanks for your note and I’m glad that your child loves the books. Obviously a terrific kid!
