Ex-private investigator Robin Llywelyn wakes up handcuffed to a hospice bed, full of morphine and with a fading memory as the cancer closes in. Unfortunately, bad detectives leave a lot of loose ends. Prosecuted for crimes he can't remember committing and pursued by cops and criminals alike for deals he has no recollection of doing, he discovers that waiting in the wilds of West Wales is a hidden fortune of the sort that men will kill for. So Llywelyn's last case sees him in a race against the reaper to score the final haul - and find out if he is the villain he appears to be.
