The case of the secret weapon
(Book)

"There's a burglar on the loose, and he's robbing houses with the help of a super-sneaky, super-stinky, secret weapon. As Head of Security, Hank knows it's his job to protect the ranch and all the buildings on it. So when a suspicious character comes sniffing around Slim's bachelor shack, Hank heads right into action. But does Hank have what it takes to save the day--even after getting caught in the spray of some very unsavory artillery?"--From publisher description.
