It's the worst storm Westingborough has known for years. The wind howls, the rain lashes - and in the bar of the Duke of York, Inspector Head is informed that a tree has come down, blocking the road to Westingborough Parva. But the evening's drama is only just beginning. For it seems that someone has used the opportunity of the blocked road to shoot Dickson of Hartlands through the window of his taxi.

Who could have committed such a risky murder? And why?

Originally published in 1937, this is a vintage mystery story from the golden age of detection.
