All Christian White wants is a quiet life. But between the FDA threatening new regulations which would bankrupt his business, and the challenges posed by his open marriage to Carol, his attractive, younger, bi wife, peace isn't anywhere on the horizon. And when he receives a letter from Billy, his old chum and sometime guardian angel from their hippie days, asking him to come to London and help him to collect on a forty-year-old IOU, Christian's other problems start to look insignificant. Because the IOU is for two hundred and fifty kilos of charas, high-grade hashish from Afghanistan. And Christian owes Billy too much to even consider refusing.
