A violent man is killed in a hit and run, and his wife is accused of the crime.

In the inky Los Angeles twilight, a man takes his dog for a walk. They are crossing the street when a station wagon comes charging around the curb, crashing into man and beast. Both are killed. The dog might have been innocent, but the man had it coming. It only takes a day for the district attorney to accuse the dead man's wife of the crime. Deirdre Charteris, a former starlet who has lost none of her looks, had every reason to want her husband dead: He was psychotic, violent, and refused to agree to a divorce. But Dee swears her innocence, and Howie Rook believes her. A retired newspaperman with a detective's sixth sense, he will do whatever he can to prove her innocence. But he will find that asking questions can be just as dangerous as going for a walk in the dark. Rook Takes Knight is part of the Howie Rook Mysteries series, which also includes Unhappy Hooligan.
