When a gruesome murder disrupts historic peace talks in London between Israeli and Palestinian leaders, Middle Eastern specialist Ayesha Ryder must decipher a cryptic message scrawled in blood above the victim's body. A letter written by Lawrence of Arabia hints at the existence of a British plan to grant independence to Palestine in the 1930s, and of a plot between a member of the British Royal Family and top Nazis. In a frantic chase through abandoned Underground tunnels, ancient catacombs and pits beneath the heart of London, Ayesha follows Lawrence's clues to his famous gold dagger, to an aged former spy who was once his lover, and to the desolate Cornish moors where she endures a cruel confrontation with her own dark past.
