Buried deep in MI6's digital archives is the most classified directory of all. It doesn't contain war plans or agent profiles, but shame: the misdeeds of politicians, royalty, business leaders and the service's own personnel. There are seven decades' worth of images and recordings, usually acquired for the sake of assessing risk, sometimes as a guard against betrayal, often engineered by MI6 for their own purposes. They are the most sensitive two thousand terabytes of data in the Service's possession. When material from the archive begins appearing online, panic spreads through the Establishment like wildfire. At first, the security breach only manifests itself in apparently random events: a suicide, a disappearance, a breakdown. But when it's discovered that the individuals concerned were all contacted by the same anonymous person, a connection comes into focus.
