The year is 1792 and it's winter in Berkeley Square. As the city sleeps, the night-watchman keeps a cautious eye over the streets and another eye in the back doors of the great and the good. Then one fateful night he comes across the body of Pierre Renard, the eponymous silversmith, lying dead, his throat cut and his valuables missing.
Broadstairs, Kent, 1851. Once a sleepy fishing village, now a select sea-bathing resort, this is a place where people come to take the air and where they come to hide.... Delphine and her cousin, Julia, have come to the seaside with a secret, one they have been running from for years. The clean air and quiet outlook of Broadstairs appeal to them, and they think this is a place they can hide from the darkness for just a little longer.
