Those two days in May seem to be a highpoint in Colin Pinnock's life: a stunning election victory, a new govenment, and junior office for himself. But among the many congratulations he receives is one hostile message, a grubby card asking: 'Who do you think you are?' Is this merely someone putting him back in his place, or do the words have a more profound meaning? Who, indeed, is he? And who were his real parents? As Colin investigates these questions he is led back in time to an old political scandal: a murder case which led to a politician's downfall and disappearance. Events in the present, however, start tangling with those of the past, and he finds himself the object of a series of incidents that at first seem designed to bring down his career with ridicule, but later actually threaten his life. A beautifully written, intriguing mystery in which past crimes come back to haunt today's innocents.
