"Strangers on a train, exchanging glances. Wondering, on a train, what were the chances..." Actually I think I might have entirely the wrong song stuck in my head. Laurence Fox and Jack Huston certainly don't end up sharing love before the night is through, although given the play opens with the latter getting up close to the former before inviting him back to his private cabin to ply him with alcohol, it does look on the cards for a bit. Guy Haynes (Fox) is an architect with a wife who won't grant him the divorce he wants, Charles Bruno (Huston) a drunken son of millionaires, who'd quite like to see his father dead so he can get his hands on the cash. Bruno proposes that the two murder each other's nemeses, providing not only an alibi but also no known connection to the killer. Guy dismisses the man as a crank but soon finds himself with a dead ex-wife, and Bruno demanding he keep his end of the bargain.
