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-dweller in Central Park, the dog walker becomes a prime suspect for murder. And 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 -- or they wont stand a dog's chance of surviving!
