In The Friend of Madame Maigret, Simenon's economic prose brilliantly portrays the Marais quarter of Paris and those who haunt its narrow streets as Inspector Maigret attempts to prove that a murder has actually been committed without a corpse anywhere to be found. As the investigation becomes increasingly complex, seemingly unconnected characters are drawn into the case, and Maigret begins to wonder if his wife's earlier strange encounter with a woman and her baby may be the missing link.
