There’s a tradition in the Sharp family that some possess the Second Sight. But is it superstition, or true psychic power? Kit Sharp is in Paris, where she is involved in a love affair with the stunning Evelyn Larsen, and working as an archivist, having inherited her historian father’s fascination with the Bayeux Tapestry.

He believes that parts of the tapestry were made before 1066, and that it was a tool for prediction, not a simple record of events. The Nazis are also obsessed with the tapestry: convinced that not only did it predict the Norman Conquest of England, but that it will aid them in their invasion of Britain. Ivy Sharp has joined the Special Operations Executive – the SOE – a secret unit set up to carry out espionage, sabotage and reconnaissance.

Having demonstrated that she has extraordinary powers of perception, she is dropped into Northern France on a special mission. With the war on a knife edge, the Sharp Sisters face certain death. Can their courage and extrasensory gifts prevent the enemy from using the tapestry to bring about a devastating victory against the Allied Forces?
