Tristam Gowers and Yves Lafeu have the flamboyance of stage matinee idols, but currently they are running a very smart restaurant, Tryst, which is much patronized by top people in the theatrical profession. Which means it's not Charles Paris' usual ambience, but this small-part player, who's more successful as an amateur detective than as professional actor, is the guest tonight of another fascinating duo, William Bartlemas and Kevin O'Rourke, wealthy collectors of theatrical memorabilia. And he is in at the death: the gruesome murder of Yves. Not Dead, Only Resting seems to be an open and shut case. Tristam caught the night boat to France within hours of a spectacular public quarrel with Yves over a pretty youth, and now he has disappeared. But of course there's much more to it than that: much more, as Charles discovers when he begins to investigate.
