No Rules, the fourth book of the hilarious Friday Barnes Mystery series―written by R. A. Spratt and with illustrations by Phil Gosier―brings even more trouble for this genius girl detective.

Friday Barnes has been deported to Switzerland . . . but we need her back!

With their go-to detective gone, Highcrest Academy has descended into chaos. Someone’s fired all the teachers as an epic prank, and suspicion falls on Ian Wainscott, Friday’s nemesis (who’s also desperately in love with her). There’s also the problem of the new vice principal and his questionable behavior. It’s hard to take someone seriously when he’s wearing tie-dyed shirts, right?

Can Friday prove Ian’s innocence, find the prankster, and save her school? If it involves running, then probably no, but if not . . . Friday’s on the case!

Praise for the Friday Barnes Mysteries:

“This second book in the Friday Barnes series is even funnier and quirkier than its predecessor.” ―School Library Journal on Under Suspicion

“Spratt continues to hit just the right mix of dry humor and suspense. Her characterization of her protagonist shines . . . Readers know that, like Sherlock Holmes, Friday will solve every mystery; the book’s fun is in seeing how she does it . . . A cliffhanger ending will have readers drumming their fingers as they wait for the next episode.” ―Kirkus Reviews on Under Suspicion

“With off-the-wall plot turns and small mysteries scattered throughout, this is the perfect choice for mystery fans with a silly sense of humor, and the cliff-hanger ending promises more sleuthing on the horizon. Gosier’s black-and-white spot illustrations add to the charming atmosphere. A sheer delight.” ―Booklist, starred review on Girl Detective

“Spratt’s (the Nanny Piggins series) effortlessly funny narration will keep readers laughing from start to finish.” ―Publishers Weekly, starred review on Girl Detective

“Quirky, tongue-in-cheek . . . delightfully eccentric . . . A good choice for voracious readers who enjoy a blend of humor and mystery.” ―School Library Journal on Girl Detective

“Spratt begins this new series with a nifty, engaging protagonist who can keep readers laughing and help young geeks feel good about themselves . . . Delightful, highly logical, and well-informed fun.” ―Kirkus Reviews on Girl Detective
