A former cop lives a quiet life in the Pacific Northwest, recovering from a brain injury that's left him with spotty memories. But his damaged mind stays he's obsessed with discovering why his best friend committed murder years before. Barely able to function without an elaborate system of notes and tape recordings (not to mention his long-suffering wife), he embarks on a dangerous road trip to piece together the past – a quest filled with designer drugs, strange clues, psychopaths with amazing culinary skills, seedy doctors and stray dogs. If he wants answers, he'll need to risk not only his life, but also his last bit of sanity.
