Lady Vanishes — Carol Lea Benjamin

The residents at Harbor View, a Greenwich Village home for "thrown away" people, love Lady, the live-in therapy dog. But when the owner dies in a tragic and bizarre hit-and-run accident and Lady vanishes, Harbor View is plunged into chaos.

Working undercover, with her pit bull Dashiell filling in for the missing Lady, Rachel Alexander discovers that the residents know more than anyone thinks they do. As she struggles to decipher the clues she finds, she comes to believe that the owner's death was no accident at all, that Lady's disappearance might also be part of a dark picture of greed, conspiracy, and murder.
