As Spiegelman's third John March novel opens, the PI is approached by his insufferable brother David for help in extracting himself from a scenario straight out of Fatal Attraction--sexually adventurous, David is being stalked by a woman he met on the Internet who is apparently interested in more than anonymous sexual trysts. Somehow, she's figured out who he is, and is threatening to reveal their illicit affair to David's wife. David, who only knows the woman as "Wren", finds himself in need of someone with his brother's unique skill set. John agrees to help his sibling, and begins digging into the woman's background. Before he can locate her, however, a corpse fitting Wren's description is fished from the Hudson, rendering his brother a suspect in a brutal murder.
Inventive, nimble, and knowing, Spiegelman cements his position as one of today's most gifted mystery writers with the action rich, yet strangely cerebral, Red Cat. John March is intelligent, sensitive and empathetic, a thinking man's gumshoe who brings a fresh perspective to the mystery genre. March is totally consumed by the difficult case, which leads him into some pretty volatile terrain, both professional and personal, teaching him lessons about himself and about his brother, with whom he has little in common. Although she never appears in a speaking role in this novel, Wren is a powerful presence in the book, exerting a strong influence over the people around her, and, eventually over John, as he comes to appreciate her as a person.
