A Old Indian Lady - In Étretat, on a Sunday evening, Valentine Besson's children gather around their mother to celebrate her birthday. During the night, Rose Trochu, the servant, dies of poisoning after drinking a glass of water intended for Valentine, which supposedly contains the sleeping pills. At least, that's what the old lady tells Maigret when, after claiming to have narrowly escaped death, she enlists him to track down the murderer.
