Maigret stumbles upon a series of murders in Fontenay-le-Comte while visiting an old school friend. On his way home from a conference, Maigret stops to visit an old school friend in Fontenay-le-Comte. A man in the same train car introduces himself and asks if Maigret has come to help solve the murder case. In fact, the man's brother-in-law had been murdered four days earlier, followed by the murder of a local widow in the same way, a blow to the head with a pipe.
