In Act I of this ingeniously-structured thriller, Detective Inspector Bruton questions actress Celia Wallis about the murder of her husband Martin. Celia is quite obviously in the clear, but Neville Smallwood, the drunken journalist sleeping in her bed, argued with Martin shortly before the murder, and the solution to the initial puzzle seems simple. Act II takes place before the murder, and all our expectations, of the characters as well as of the plot, are turned on their heads.-2 women, 4 men, 2 women or men
