A decade before, a woman matching Hayley's exact description died in a suspicious diving accident--at the side of the man giving Harding his orders. Now the ring, said to have been cut off the finger of a drowned British naval commander in 1707, is at the center of a many-tendrilled puzzle. Uncanny resemblances . . . stunning contradictions . . . Then Hayley's sudden disappearance . . . For Harding, one misstep and a handful of coincidences ignite a search through dozens of lives, back into English history and the age of the Black Death, and forward to a fatal meeting in Germany . . . to find Hayley, her true identity, and the most shocking secret of all.
