Maigret and the Burglar's Wife

Maigret is visited by Ernestine, the wife of a burglar known as 'Sad Freddie'. Whilst breaking into a house he discovered a body and is so alarmed he has fled the country. The trail leads Maigret to a dentist who lives with his domineering elderly mother. His wife has gone missing but Maigret needs to find a body if he is to provide a link.
