Professional dog walker Ellie Engleman is more than just a pal to her pooches? she can also read their minds. When Ellie and her terrier mix Rudy find the corpse of a troubled-but-harmless park-dwellerin Central Park, the dog walker becomes aprime suspect for murder. When it turns out Rudy is the sole beneficiary of the victim?s inheritance, Ellie, Rudy, and Detective Sam Ryder follow the trail of clues to a key to a safety deposit box that just might point to the motive and help them sniff out the real killer.
