This murder-mystery, by Agatha Christie, centres on a weekend at The Hollow, home of Sir Henry and Lucy Angkatell, about eighteen miles from London, one weekend in early September in 1952, when an unhappy game of follow-my-leader develops into sinister murder and intrigue.
Dr John Cristow is at the centre of the trouble, for at The Hollow are his mistress Henrietta, actress Veronica, his ex-mistress, and his wife Gerda.
The plot thickens with the involvement of Edward, who is in love with Henrietta, and Midge, who in turn is smitten with Edward.
Veronica is also devoted to Cristow in this cobweb of deceit, and threatens that if she cannot have him, no-one else will.
Within minutes of the opening, one of them is dead, and nearly everyone had a motive, most had the opportunity, but whodunnit?
