Query: One of the most convincingly complex mysteries I've read

Garve is an outstanding writer and this is my favorite. A well-respected lawyer is accused of accosting a woman on a train and disinterested witnesses support the accusation. Then she turns up dead and he is charged with murder. His sons set out to clear his name. They soon discover who has set the frame and why--the difficult part is proving how. An exceedingly clever mystery that portrays both the humor and terror of false witness.
