What was the woman doing here? In a stable, wearing pearl earrings, her stylish bracelet and white buckskin shoes! She must have been alive when she got there because the crime had been committed after ten in the evening.
But how? And why? And no one had heard a thing! She had not screamed. The two carters had not woken up.

Inspector Maigret is standing in the pouring rain by a canal. A well-dressed woman, Mary Lampson, has been found strangled in a stable nearby. Why did her glamorous, hedonistic life come to such a brutal end here? Surely her taciturn husband Sir Walter knows - or maybe the answers lie with the crew of the barge La Providence.
