Summary: A complex tale of murder, deceit and greed in an isolated country community. Maigret has been interrogating a mysterious Dane, Carl Andersen, for hours without a confession. Why was the body of a diamond merchant found in his car at his isolated mansion? He's either innocent or a very good liar. What does his beautiful but vulnerable sister know? And what compels everyone at the Three Widows Crossroads to be so secretive? Maigret sets out to find his killer.

Summary: Maigret investigates the murders of two women who are seemingly unconnected yet share a mysterious bond. The first, Arlette, is a beguiling showgirl from a seedy club who arrives at the police station to report two men she overheard discussing the murder of a Countess. But Arlette is shifty and eventually rushes from the building, only to be found strangled in her apartment the next morning. Meanwhile, Maigret hears word of a Countess who has also been found strangled, her valuables untouched and only a few mysterious leads for the detective to follow up. What connects the two? And should Maigret have done a better job of protecting Arlette when she came to him in her hour of need?
