For John Rebus, forty years may have passed, but the death of beautiful, promiscuous Maria Turquand still preys on his mind. Murdered in her hotel room on the night a famous rock star and his entourage were staying there, Maria's killer has never been found. Meanwhile, the dark heart of Edinburgh remains up for grabs. A young pretender, Darryl Christie, may have staked his claim, but a vicious attack leaves him weakened and vulnerable, and an inquiry into a major money laundering scheme threatens his position. Has old-time crime boss Big Ger Cafferty really given up the ghost, or is he biding his time until Edinburgh is once more ripe for the picking?
