D.I. Hal Challis is in trouble with the boss and missing his lover, Ellen Destry, who is overseas. But there's plenty to keep his mind off his problems. A rapist in a police uniform stalks Challis's Peninsula beat, there is a serial armed robber headed in his direction and a home invasion that's a little too close to home. Not to mention a very clever, very mysterious female cat burglar who may or may not be planning something on Challis's patch.
