Maigret and the Old Lady: Georges Simenon

`He had realized that it was her eyes as much as her vivacity that made her look so young. They were of a blue that was paler than the September sky over the sea and still had an expression of surprise, of wonderment`

When a charming elderly widow appeals to him for help, Inspector Maigret travels to a seaside village in Normandy - uncovering a lost fortune and some poisonous family politics.
