A collection of characters apparently drawn directly from old English detective fiction arrive for a party in an old country house.
Among them there is an old Navy man, a ditzy woman, and a flamboyantly eccentric butler who keeps trying to serve up his own cocktail creation, the "Zombie Whammy".
There is also Andreas Capodistriou, a smooth talking serpent of a man who demonstrates to each guest in turn that he knows something compromising about them and is intent on blackmailing each one.
The act climaxes as each guest, having a reason to want Capodistriou dead, conceals his or her self on the set to lie in wait for the victim, who arrives alone and kneels to perform his evening prayer.
He reveals that he is actually an actor, and was hired to participate in a role-playing party for the house's owner, who would act as detective and solve the mystery.
