The Lost Key

A stolen drive. A quiet war. No alarms.

When classified code disappears from GCHQ, London doesn’t hear an explosion. It feels a silence.

The file is called the Lost Key. Whoever controls it can rewrite financial records, crash infrastructure, and turn trusted networks into weapons. It was never meant to leave the building.

Former SAS operator James O’Neill thought he was done with all of it. Now someone has put his name in the wrong briefings, bodies are starting to fall, and the only way out is back in.

Book One of the James O’Neill Series. For fans of Lee Child, Tom Clancy and Mark Greaney.
