The dancer at the Gai-Moulin

In the darkness, the main room is as vast as a cathedral. A great empty space. Some warmth is still seeps from the radiators. Delfosse strikes a match. They stop a moment to catch their breath, and work out how far they have still to go. And suddenly the match falls to the ground, as Delfosse gives a sharp cry and rushes back towards the washroom door. In the dark, he loses his way, returns and bumps into Chabot. Maigret observes from a distance as two boys are accused of killing a rich foreigner in Liege. Their loyalty, which binds them together through their adventures, is put to the test, and seemingly irrelevant social differences threaten their friendship and their freedom.
