Kate Morgan, a young Harvard grad working at a private investigation company, introduces us to a world of intrigue, where nothing is as it seems. While uncovering the secrets concealed in a centuries old tome, she follows leads on two cases - one a covert operation for the US government, and the other a legitimate operation for a beguiling European businessman.
Though Kate Morgan's story dominates, through beautifully crafted historical passages we follow the uncertain fate of a young Christopher Marlowe, the playwright, poet, and gentleman spy of Queen Elizabeth's secret service. As the two stories progress, we realise that Kate's own fate may not be so far from her literary hero's, as she draws closer to uncovering the mysteries behind Marlowe's ill-fated demise.
