Murder of a Bookman — Gary Lovisi

When the police are asked to investigate the brutal murder of bookseller Brian MacDonald, who's been stabbed in the back with his letter opener, they have no trouble locating suspects, because MacDonald has been less than honest in his dealings. But Detective Bentley Hollow has problems of his own: his wife has left him, and he detests his new partner. Still, he has to find a solution to the crime, and when he does, his life will be irrevocably changed. The first in a new series.
