When the bones of a woman are discovered on the property of an old family friend, Kevin Kerney is arrested for the forty-five-year old homicide of Kim Ward, his college girlfriend. Charged with the crime by his son, New Mexico State Police Lieutenant Clayton Istee, Kerney must prove his innocence in the face of compelling evidence against him. With no alibi and no witnesses who can come to his defense, Kerney and his wife, Sara Brannon, embark on a harrowing journey to reconstruct long-past events and find the real killer. With few clues and little hope of out-smarting Clayton and his team, Kerney and Sara race to identify one person who can clear his name. In the process, they discover an unsolved crime, encounter dangerous enemies, and unravel shocking family secrets.

“Complex, entirely original and whip-smart, Residue is all but impossible to put down. And Michael McGarrity once again proves himself a master.” – John Lescroart, New York Times best-selling author.
