A tidy collection of slightly bizarre cases enlivens Shannon's latest for Mendoza and the L.A.P.D. A handsome, well-dressed, very polite rapist strikes only on Saturday afternoons. A thief uses a huge Doberman as a threat weapon. Harmless, middle-aged men are murdered in a seemingly meaningless series. And then there's George Parmeter, an animal-hating pharmacist with fascist leanings, who's found dead in his driveway on a tiny, quiet, dead-end street. Add in some other murders, some incest and stick-ups--and it's one of the better recent case-montages from the reigning doyenne of the US police procedurals.
