The Devil offers to help him find the truth. He never promises the truth won’t destroy him. Eleven months after a hit-and-run driver killed his wife and three daughters, Louisiana police officer Daniel Renaud has little left beyond an empty house and an investigation he cannot abandon. Placed on leave, isolated by grief, he keeps searching for the person who drove away. Then a stranger at a bar introduces himself as Lucifer. Daniel isn’t impressed. But the stranger brings something no one else has: a lead that holds up. No contract. No payment. No claim on his soul. As their uneasy partnership becomes an unlikely friendship, Daniel follows a trail of altered records, frightened witnesses, and a powerful foundation determined to keep its secrets. Meanwhile, a piano technician named Evelyn Shaw offers the possibility of a life he thought had ended with his family. For the first time, Daniel has something to lose again. But someone is deciding which truths he can bear. And the closer he comes to identifying the driver, the harder it becomes to separate the people helping him from the people keeping him in the dark. Set in the bayou country of Southeast Louisiana, The Devil’s Best Friend blends supernatural suspense, a criminal investigation, and an intimate story of grief, love, and betrayal. How do you demand the truth when it could cost you everyone you have left?
