My Son, the Murderer

In this mystery from an Edgar Award–winning author, sleuth Peter Duluth steps in when his rebellious nephew is charged with murder.
 
Patrick Quentin, best known for the Peter Duluth puzzle mysteries, also penned outstanding detective novels from the 1930s through the 1960s under other pseudonyms, including Q. Patrick and Jonathan Stagge. Anthony Boucher wrote: “Quentin is particularly noted for the enviable polish and grace which make him one of the leading American fabricants of the murderous comedy of manners; but this surface smoothness conceals intricate and meticulous plot construction as faultless as that of Agatha Christie.”
 
Jake Duluth is a man alone. Three years after the suicide of his beloved wife, the wall between Jake and his son, Bill, has only grown higher. Bill’s constant impulsiveness has driven Jake to distraction, while Jake’s constant concern for his publishing business alienates Bill even more.
 
But when Bill is accused of murdering Jake’s business partner after falling in love with the man’s much younger wife, Jake has no choice but to believe his son and call in someone with much more experience in such sinister matters—his brother, Peter.
 
Now, with Bill’s life at stake, Jake and Peter must follow a trail of secrets and twisted loyalties if they are going to uncover a culprit neither could have ever imagined.
