Written by Agatha Christie. Adapted by Archie Scottney.

Martin Jarvis performs this riveting 1920s story. Mr Satterthwaite is staying at the Denman's country home. There's to be a performance in the grounds of a neighbouring mansion that evening - a 'masquerade' and a ballet.

But a motor accident means that two new dancers have to be found to replace the visiting professionals. There seem to be unresolved mysteries here. Does Anna Denman harbour a secret? Is there a secret, too, concerning her husband? Why is Mr Harley Quin staying in the country house? And then, during the performance, Mr Satterthwaite begins to perceive the truth of what is happening. But the revelations which follow concerning Mr Quin are surprising and frightening. Mr Satterthwaite has never had to deal with anything quite like this before.
