Sleeping Dogs Lie — Samantha Downing

From the internationally bestselling author of My Lovely Wife and For Your Own Good comes a twisted, entertaining novella about a dog walker swept into a criminal investigation when her client winds up dead.
 
Shelby works as a dog walker in northern California, and she's just finished up her bi-weekly trip to the park with a husky named Pluto. When she brings him back to his house, she finds his owner -- Todd Burke, a well-known local businessman and founder of an organic supplements company -- lying on the bathroom floor, dead. A detective arrives on the scene. As she interviews Shelby, the body is inspected by a medical examiner, and more cops search Todd's home, it becomes clear that the victim's life was less picture-perfect than his clean-cut persona might lead you to believe.
