The best detective duo is back in the third installment of the King & Kayla series by Dori Hillestad Butler! In King & Kayla and the Case of the Mysterious Mouse, King and Kayla are playing fetch with their friends, Jillian and Thor. But when Jillian throws King’s favorite ball over the fence and brings it back, King can smell that it’s not his ball. It’s up to King and Kayla to find the missing ball, but can King help his human figure out where it went—and who has it?

Filled with deadpan humor perfect for dog-lovers, this fun mystery series is a great way for transitional readers to practice their sleuthing skills by gathering facts and thinking analytically. The simple, straightforward language and repetition within and between the books in the series helps boost confidence in readers who are beginning to transition into longer chapter books.

“Confusion, mischief, and silliness abound. Kids who don’t always have the vocabulary to express themselves will sympathize with this waggish pup and his earnest desire to be understood by his human.” —Kirkus Reviews

“Budding detectives will have the benefit of both King’s discoveries and Kayla’s reasoning as they piece together the clues…. A welcome addition to collections supporting the transition from picture books to chapter books, this title will appeal to both dog lovers and mystery buffs.”—School Library Journal
