from the back of the book:
Madame Maigret's trip to the dentist brings surprising insight to a baffling case.
When two human teeth are found in the furnace of a Flemish bookbinder, police quickly take him into custody. Blood stains are discovered on a suit in the suspect’s closet, but he denies ownership. Then, a strangely heavy suitcase found in his workshop disappears. A neighboring shoemaker is willing to talk but his story changes with successive trips to the local tavern and is discredited. Without a body, the case seems impossibly perplexing –until Madame Maigret offers her help.
