Murder, He Howled - Parker Doyle Mysteries, #1

When Parker Doyle is bitten by what he thinks is a rabid wolf it turns out to be an honest-to-goodness werewolf which takes a bite out of his normal life as a college writing professor. His days--and nights--are now fraught with fear of discovery, learning to cope with the idea that he is a potential killer during the full moon and his lack of normal feminine companionship. The only good thing to come out of the episode is selling his first novel, a detective series about a Denver police officer who just happens to moonlight as a werewolf.
The series is a howling success. Then people start turning up dead, and Parker is connected to them all: a fellow mystery writer wildly jealous of Parker and a beastly student who attacked him in front of fellow students. Now Parker is being framed for the murders-but by whom? And why? He has no option but to use his curse to help solve the crimes. Add to the mix a crazy fan, a sexy groupie determined to get her claws into Parker and a sweet-natured animal lover fascinated with wolves.
