In this story, Sturgis is downhearted about his inability to find the murderer of Katherine Hennepin, a young female bookkeeper. She apparently was killed during a dinner date at home; the table was set for two and the cuisine was selected with care. With no suspects, the case was put on the back burner.
Weeks later, another woman’s body is found in a parking garage. It is Ursula Corey, who has been gunned down; this appears to be a revenge killing. Alex and Milo settle on two possible suspects. But then another murder similar to Hennepin’s pops up. And then others, all with dinner date themes, leading Alex and Milo to believe that a serial killer is at large. Superior detective skills and psychological studies help them with the surprise identification of the murderer.
