Lady Vanishes by Carol Lea Benjamin

From former detective turned noted author and dog trainer, Carol Lea Benjamin, comes the fourth book in the critically-lauded Rachel Alexander mystery series, with a sharp new package--and for the first time in mass market! 

Dash, Rachel Alexander's pit bull terrier, has come to be known as half a sleuthing team. But when not called upon to solve crimes he has another very important job: that of a therapy dog, working with people who are developmentally challenged.

Lady, a mop-coated puli, was the therapy dog at Harbor View, a Greenwich Village home for "throw away" people. But now lady has vanished...and the owner of the home has been killed in a bizarre and mysterious hit-and-run accident. Rachel and Dash are the perfect duo to tackle this mystery: she can find the answers and Dash can bring a sense of calm and order to the residents.

As the pieces start coming together, Rachel and Dash not only expose an ugly plot, but also help some innocent victims find justice in a world that too often ignores them.
