Master sleuth Hercules Poirot has time on his hands, four clocks, all set for 4.13, and all left at the scene of murder.
In the tidy sitting-room Detective Inspector Herdcastle examines the assembled witnesses for clues - a blind lady, a young secretary and an innocent passer-by.
Poirot must find them first...but will he have time?
