Thriller written by playwright Patrick Hamilton and adapted for film by Alfred Hitchcock.

"At precisely 6.45pm young Ronald Kentley was strangled with a rope by two fellow undergraduates, who subsequently deposited his body in a chest. Later that same evening his friends and family, including the deceased's father, are invited round to a tea party.

As the evening progresses the perpetrators increasingly test their ingenuity and morality to the limit; but will any of their guests realise their dark secret?"
