The Ouroboros Key: A Relic Code Thriller

By Clyde Sutherland

A stolen alchemical ring. A secret longevity clinic. A cure that may be feeding on the dead.

After exposing the truth behind the ankh in Book 1, artifact conservator Mara Vale is pulled into a new case when a dead accountant's Basel storage locker reveals an ouroboros ring engraved with her father's private mark. The serpent swallowing its tail is supposed to mean renewal, eternity, and transformation. In the hands of Aion Therapeutics, it has become the emblem of something far darker.

From Prague clock archives and Swiss banks to a remote Alpine sanatorium, Mara follows the ring into a world of elite science, missing patients, sealed donor records, and a hidden medical program where the powerful promise to outrun death.

But the ring is not the treasure. It is the key.

And what it unlocks could destroy families, foundations, clinics, and reputations across Europe.

The Ouroboros Key is a fast, atmospheric artifact thriller for readers who enjoy ancient symbols, modern conspiracies, museum mysteries, coded objects, and intelligent suspense in the tradition of historical and archaeological thrillers.
