The Phantom Signal

Coming Soon.

A World War Two Espionage Thriller Set at Bletchley Park

Someone inside Britain’s most secret intelligence operation is feeding false information to the Admiralty. Phantom signals, fabricated intercepts indistinguishable from the real thing, have been seeded into the processing chain and dispatched to naval command, quietly distorting the intelligence on which convoy routes and the men sailing them depend. Thirty-seven signals. Months of systematic manipulation. And the only person who noticed is dead.

Marion Graves, cryptanalyst, twenty-four years old, was found in the lake at dawn. The circumstances of her death cannot be explained by the official account, and Hazel Ward, Bletchley’s internal security officer, methodical, watchful, operating at the precise edge of her authority, is not prepared to let that account stand.

What Hazel is uncovering is not a single murder. It is the architecture of a betrayal built entirely from the inside: no foreign handler, no ideological motive, no enemy network. Someone with deep knowledge of the system, trusted by everyone around them, has been corrupting Ultra’s output for reasons that will prove to be devastatingly, uncomfortably human.

Her investigation puts her immediately at odds with Captain Alistair Fenn of MI5, whose arrival at the Park is swift, whose authority is unambiguous, and whose focus on a foreign national in Hut 6 is a little too convenient for an institution that would rather find a spy than a traitor. The deeper Hazel goes, the clearer it becomes that the cover-up is not incidental to the crime. It is its logical continuation, prosecuted by different hands and for reasons the establishment considers impeccably sound.

Outside the wire, Detective Inspector Chadwick of Buckinghamshire Constabulary is asking questions of his own. He cannot be told what he is actually investigating. He is going to be essential anyway.

A wartime mystery of conscience, compromise, and the cost of secrets, The Phantom Signal is a historical espionage thriller set at the heart of Britain’s Ultra programme during the Second World War. For readers of Kate Quinn’s The Rose Code, Robert Harris’s Enigma, and Elizabeth Wein’s Code Name Verity.
