Maigret and the Reluctant Witnesses — Georges Simenon

When the head of a powerful Parisian family business is murdered in his bed, Maigret must pick apart the family's darkest secrets to reveal the truth

"The curious thing was that there seemed to be no grief here, only a strange dejection, a kind of uneasy stupor..."

Maigret is called to the home of the high-profile Lachaume family where the eldest brother has been found shot dead. But on his arrival, the family closes ranks and claims to have heard and seen nothing at the time of the murder. Maigret must pick his way through the family's web of lies, secrets, and deceit, as well as handle Angelot, a troublesome new breed of magistrate who has waded into the case. And it's the estranged black sheep of the family, Veronique, who may hold the key to it all with her knowledge of the depths to which the family will sink to protect their reputation.

Maigret and the Reluctant Witnesses is an engrossing mystery that examines the intricate tangle of artifice that can entrap even the most influential families.
