Les Petits Muertres D'Agatha Christie

A movie star commits suicide in the middle of filming. Superintendent Laurence decides to spend a bit more time looking at the life of the actress: she was beautiful, rich, famous, adored by men and hated by women. So many motives for murder.

Two murders and two unusual witnesses: a dog and ghosts! A case that is not to the liking of Superintendent Laurence, especially since his mother, the whimsical Alexina, decides to get involved in the investigation. Worse, she has taken a liking to Alice, who would make an ideal daughter-in-law.
