Post-war Cairo is a city of shadows—where ex-Axis smugglers, double-dealing British officers, and Soviet agents stalk the burning streets.

When archaeologist Lionel Harcourt is murdered, he leaves behind a coded papyrus pointing to a forgotten RAF vault buried deep beneath the Sahara railway line. Inside it lies a secret so explosive it could shatter the Middle East—and every nation that touched it.

Enter Jack Falcon.

Espionage veteran. Reluctant hero. The only man Harcourt trusted.

With former resistance fighter Elena Markovic, brilliant linguist Lina Ravelle, and the unpredictable Franz Adler, Falcon must survive sandstorms, sabotage, and a ruthless Soviet rezident determined to claim the secret for Moscow.

From the crowded platforms of Cairo’s Ramses Station to a deadly sandstorm chase along an abandoned desert railway, Falcon races against time to unlock the Cairo Cipher—only to discover a hidden ledger revealing decades of covert deals, betrayals, and a shadow conspiracy older than the war itself.

Some secrets should stay buried.

Some wars never end.

And in the desert, truth is the most dangerous weapon of all.

The Cairo Cipher is a fast-paced, atmospheric spy thriller perfect for fans of Ken Follett, Alistair MacLean, and classic post-war espionage.
