This is a 100 per cent win from Lovesey, who proves an embarrassment of authorial riches by managing to keep the plot propulsive, the dialog pithy, the cops’ jokes and good humor strong, and the characters easily identifiable. A great procedural whodunnit with an interesting maguffin. This is the 14th book in the “Peter Diamond” series, and it’s enough to make readers flip back through the previous 13.
