Sasspants, PI(G), the world's fluffiest detective, is back on the case―or she will be, if her sidekick Hamisher can convince her there's really a mystery afoot. Hamisher has made up so many stories, Sasspants doesn't believe him. But one by one the mice in Mr. Venezi's pet shop are going missing, and all the spooky clues point to . . . a ghost! Once our shaggy Sherlocks start digging for answers, they will stop at nothing to ferret out the truth!Sasspants is a guinea pig with a penchant for puzzles. She lives in a pet shop in which the animals are smarter than the shopkeeper, who mistakes hamsters for koalas, chinchillas for camels, and hermit crabs for tractors. When the “g” falls off the sign on Sass’s cage, Hamisher the koala—that is, hamster—is positive she’s a Private Eye. And when there are no mysteries to be solved, Hamisher is happy to create some!
