"C" Is for CorpseAudiobook CD - 1993 | Library ed.
Huge chunks of his memory were lost but he knew someone had tried to kill him and that the "accident" was deliberate. He knew he had the key to something that made him dangerous to the murderer but he didn't know what. No one believed him...so he hired Kinsey Millhone.
Three days later Bobby was dead. But Kinsey never welshed on a deal. She'd been hired to stop a killing, now she'd find the killer instead.
