Ken Grimwood - Two Plus Two

Grimwood used the pseudonym Alan Cochran on his novel Two Plus Two (Doubleday, 1980), but in Replay he offered a clue to Two Plus Two's true author with a sequence in which the main character of Replay hides his identity by using the name Alan Cochran. Behind Doubleday's cover blurb, "A Terrifying Novel of Murder in a Swinging Social Club," the storyline follows two Los Angeles detectives investigating a trio of murders. Doubleday described the book with this summary:

For anyone who has never been to a swinging couples-only club, Two Plus Two will offer some surprises; and surprises were certainly in store for detectives Jason Price and his attractive partner, Brooke Merritt. Three seemingly unrelated murders have occurred in the Los Angeles area and the police have only a single lead — each of the victims, one male and two females, were members of the exclusive Two Plus Two club. To investigate, Lieutenant Dan Ryan calls in the team of Price and Merritt. Their assignment — to go undercover and infiltrate the club, posing as a new swinging couple. As their research begins, they find a world unlike any other; a world where every carefully chosen amenity is geared to easing each casual sexual encounter; and a world which, unbeknownst to its members, harbors a clever, homicidal madman. Two Plus Two opens the doors of a closed-door milieu, that of the on-the-premise-swinging club—intriguing, mysterious, and, sometimes, deadly. It also introduces us to two new detectives—one male, one female—of whom more will be heard.
