Jamie Saintclaire is an art recovery expert, the kind of man who knows where stolen masterpieces go and how to get them back. In The Doomsday Testament, a personal discovery draws him in: his grandfather, a quiet Anglican clergyman, turns out to have been a decorated SAS veteran with a wartime secret sewn into the pages of his diary.
The series uses that template across four books — a lost relic, a historical conspiracy, and Saintclaire racing to stay ahead of people willing to kill for the answer. The Isis Covenant involves ancient Egyptian mysteries, The Excalibur Codex goes after Arthurian legend, and The Samurai Inheritance takes the hunt to Japan. The books are quick reads with strong period detail and genuine momentum.
