A first ink drawing showed a hanged man swinging from a gallows on which perched an enormous crow. And there were at least twenty other etchings and pen or pencil sketches that had the same leitmotif of hanging.
On the edge of a forest: a man hanging from every branch.
A church steeple: beneath the weathercock, a human body dangling from each arm of the cross. . . Below another sketch were written four lines from Francois Villon's Ballade of the Hanged Men.

On a trip to Brussels, Maigret unwittingly causes a man's suicide, but his own remorse is overshadowed by the discovery of the sordid events that drove the desperate man to shoot himself.

This novel has been published in previous translations as Maigret and the Hundred Gibbets and The Crime of Inspector Maigret.
