The fourth entry in the irresistible New York Times bestselling mystery series featuring canine narrator Chet and his human companion Bernie Little—“the coolest human/pooch duo this side of Wallace and Gromit” (Kirkus Reviews)

Humor and intrigue combine for a “thoroughly entertaining comic mystery” (Booklist) as Spencer Quinn’s engaging and unlikely team of crime solvers takes on the case of a boy gone missing from a wilderness camp.

The kid’s mother thinks her ex-husband snatched their son, but Chet’s always reliable nose leads Bernie in a new and dangerous direction. Meanwhile, matters at home get complicated when a stray puppy that looks suspiciously like Chet shows up. Affairs of the heart collide with a job that’s never been tougher, requiring our intrepid sleuths to trust each other even when circumstances—and a rival P.I.—conspire to keep them far apart.
