From the author of the successful Thomas the Falconer mysteries comes a new historical series featuring Elizabethan intelligencer Martin Marbeck....

1600: A new century dawns. War with Spain has dragged on for 15 years, the conflict in Ireland for six. Unease stalks England in the dying years of Elizabeth I’s reign, and Elizabethan intelligencer Martin Marbeck is bored.

Then a message from his spymaster, Sir Robert Cecil, arrives: the existence of a spy has been discovered, code-named Morera, and Marbeck must uncover the true identity of this traitor quickly, before rumours of the young King Philip III forming a new Armada prove themselves to be true.
