I bought the book from Amazon.com -- at 99 cents who could resist? -- but haven't had a chance to read it. Here is a quote from the Amazon.com site:
Jamie Beaverbrook is an English psychologist working for the Los Angeles Police Department. His job - to sort out the insane from the sane, the crazies from the ones who are pretending to be crazy. But Beaverbrook's life is turned upside down one night when the police find a girl crouched over a man with his throat torn out. The girl has blood on her lips but claims she only found the body. Beaverbrook doesn't take long to establish that she's totally sane - but he is forced to face a bigger question. Is she a vampire? And what does she want from him?
I look forward to reading more of Stephen Leather's books in the future.
