Press release One woman's courage in the face of destruction June 30, 2025

A missing scientist. A murdered spy. A cipher that could change the course of the war.

London, July 2025 – dp books is proud to announce the upcoming release of The Shadow Code by Suzy Henderson, one of our bold new frontlist titles for 2025 and the latest addition to the beloved Heroes of War series, now available for pre-order.

Set against the backdrop of the Blitz, The Shadow Code introduces WPC Ellie Harcourt, a tenacious young officer who stumbles into the heart of a deadly conspiracy when she discovers a coded message on the body of a murdered civil servant. The cipher references ‘Kingfisher’ – a name known only in the deepest corners of Whitehall.

With MI5 stepping in, Ellie is assigned to work with officer Jack Stratton, an old family acquaintance with a sharp tongue and even sharper memory. But when another agent is found dead and Ellie’s own father, a radar scientist, disappears without a trace, the stakes become deeply personal.

As Ellie proves herself capable of cracking parts of the code, she’s pulled further into the investigation – and deeper into danger. What she and Jack uncover threatens not only the people closest to them but the entire war effort. With traitors operating from the inside, The Shadow Code is a gripping tale of secrets, sabotage, and the extraordinary women who helped defend Britain from within.

Packed with tension, historical detail, and a slow-burn partnership at its core, The Shadow Code is perfect for fans of wartime thrillers with women front and centre.

The Shadow Code is now available for pre-order on Amazon and Kindle Unlimited, with official release set for August 28th 2025.
