For John Rebus, 40 years may have passed, but the death of beautiful, promiscuous Maria Turquand still preys on his mind. She was murdered in her hotel room on the night a famous rock star and his entourage were staying there, and 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?
