Maigret: Season 5

Even on holiday, Maigret must investigate crime.

Maigret returns to the small village where he was raised, after receiving an anonymous letter telling him that a crime would take place in the town church on All Saints' Day.

Maigret tries to find the person responsible for the death of a harbor master who, after disappearing for six weeks, could no longer speak and had no physical reactions to anything.

When Joseph Heurtin escapes from prison, it's because Maigret has arranged it. And if Heurtin didn't kill that old woman, who did?
