Following a mysterious explosion, the offices of Excelsior Joinery Company are no more; the 3 directors are killed and the peace of a quiet town in Surrey lies in ruins. When the supposed cause of ignited gas leak is dismissed and the presence of dynamite revealed, Superintendent Littlejohn of Scotland Yard is summoned to the scene. But beneath the sleepy veneer of Evingden lies a hotbed of deep-seated grievances. Confounding Littlejohn's investigation is an impressive cast of suspicious persons, each concealing their own axe to grind.
