Death and decapitation seem to go hand in hand in the Devon village of Aller. When the first victim's head is sent floating down the river, the village's rural calm is shattered. Soon the corpses are multiplying, and the entire community is involved in the hunt for the murderer. Whilst many chase false trails, it is left to Gervase Fen, Oxford don and amateur criminologist, to uncover the sordid truth.

Equal parts compelling, witty and ingenuous, this novel is a classic example of great British detective fiction.

First published in 1977, Glimpses of the Moon was Edmund Crispin's ninth and final novel.
