'Life for sale. Use me as you wish. I am a twenty-seven-year-old male. Discretion guaranteed. Will cause no bother at all.'

When Hanio Yamada realises the future holds little of worth to him, he puts his life for sale in a Tokyo newspaper, thus unleashing a series of unimaginable exploits. A world of murderous mobsters, hidden cameras, a vampire woman, poisoned carrots, code-breaking, a hopeless junkie heiress and makeshift explosives reveals itself to the unwitting hero. Is there nothing he can do to stop it? Resolving to follow the orders of his would-be purchasers, he comes to understand what life is worth, and whether we can indeed name our price.
