This book was published in 1942 along with six other books written that year by Georges Simenon; two Maigrets and four novels. Simenon was living in Fontenay le Compte, a locale which figures in this book. It is an early Maigret novel showing the author still testing the Chief Superintendent's character, moods, his dream like analytical trances and the psychology of murderers. The confusing plot weakens in the middle and at the end when the reader is adrift to speculate on the suspect Charles Dandurand's fate. He relishes the twisted sex life of the wealthy dead spinster and her lover; much like his own. Simenon's real life distractions can be presumed; he was living in a castle in the Vendee, the Germans chopping at the fence posts, and his multi tiered personal life in temporary disarray. He, however, followed up this book with one of his strongest Maigret's roman policier, "Maigret and the Majestic Hotel.
