Edward Bennett, a playwright, and his wife Sorel Bennett, an actress, flee London and head to Cookham after a disastrous opening night. But various guests arrive unexpectedly - a conservative politician, a fiery socialist, a nearsighted ingenue, a zany modern dancer - each with a long-held secret. When one of the guests is murdered, it's left to Bridgit, the feisty Irish maid with a macabre interest in homicide, to solve the crime.
