The captain of the Newhaven to Dieppe steamer spots a small pleasure yacht lying motionless in the water and, on closer inspection, sees a body lying on the deck. When members of his crew go aboard the yacht, they find not one male corpse but two. The dead men were chairman and vice chairman of Moxon General Securities, one of the largest financial houses in the country. Inspector Joseph French of Scotland Yard is called in. French soon discovers that Moxon's is on the brink of collapse.

When Sir John Magill, the wealthy Irish industrialist, fails to show up at his hometown on a well-publicised visit, neither his family nor the Belfast police can explain his disappearance. Foul play is suspected when his bloodstained hat is discovered, and Scotland Yard is called in. With his characteristic genius for reconstruction, Inspector French evolves a gruesome theory about what happened to the elderly man, but his reputation - and that of Scotland Yard - will depend on finding out who was responsible.
