The Recommended Reading Order for Jamie Saintclair
The best and most rewarding way to read the Jamie Saintclair series is in its official publication order.

Here is the recommended reading path for the series:
- The Doomsday Testament (2011)
- The Isis Covenant (2012)
- The Excalibur Codex (2013)
- The Samurai Inheritance (2014)
The Jamie Saintclair Books Up Close
1. The Doomsday Testament (2011)
The series opens with The Doomsday Testament, introducing readers to Jamie Saintclair, an art recovery specialist based in London. When his grandfather, Matthew, dies under suspicious circumstances, Jamie discovers a secret diary revealing that the quiet old man was actually a decorated SAS war hero. Tucked inside the journal is a silk map covered in Nazi occult symbols. Jamie’s search for a lost Raphael painting becomes a deadly chase across Europe—taking him from German SS fortresses like Wewelsburg Castle to deep caves in Tibet and alpine canyons in Switzerland. Alongside journalist Sarah, Jamie must piece together clues about Hitler's 1937 expedition to Tibet to unlock a truth his grandfather died to protect.
2. The Isis Covenant (2012)
In the second installment, The Isis Covenant, Jamie is called in by a Boston detective to assist in a gruesome murder investigation where the killer has left behind symbols linked to Nazi occult units. The investigation shifts into a desperate search for the Crown of Dido, a Phoenician artifact coveted by Nazi occultists during World War II. The crown is useless without its matching piece: a legendary diamond known as the "Eye of Isis." Jamie is thrown into a web of greed and ancient mythology, tracing a secret that stretches from the reign of Emperor Nero to the fall of Berlin in 1945.
3. The Excalibur Codex (2013)
In The Excalibur Codex, the focus shifts to Arthurian myth combined with WWII history. In 1941, twelve SS generals gathered in eastern Poland to perform a dark ritual using what they claimed was Excalibur, the legendary sword of King Arthur, hoping to turn the tide of the war. Decades later, Jamie is hired by his wealthy friend and collector Adam Steele to track down the mythical blade, which is mentioned in a codex attached to a deceased German veteran's will. From the ruins of Hitler's "Wolf's Lair" to remote corners of Poland, Jamie faces modern-day extremists who are willing to kill to claim the sword for their own nationalist agenda.
4. The Samurai Inheritance (2014)
The final book in the series, The Samurai Inheritance, expands Jamie’s adventures to the Pacific. In 1943, the plane carrying Japanese Admiral Isoroku Yamamoto was shot down over the island of Bougainville, lost with a highly classified document case. In the present day, a wealthy mining tycoon commissions Jamie to recover a preserved Solomon Island warrior's head that vanished from a Berlin museum in 1945. Jamie's search takes him from Berlin to Tokyo, where he discovers that the missing skull is directly linked to the secrets of Yamamoto's crashed plane, forcing him to outwit lethal modern-day interests.
Understanding the Timeline: Publication vs. Chronological Order
In terms of modern narrative progress, the chronological order of the series matches the publication order exactly, beginning in 2008 in the first book and progressing forward. However, every book in this series uses a dual-timeline narrative structure. A significant portion of each novel features flashback sequences detailing events in the past—often during World War II, but sometimes stretching back to ancient Rome or antiquity—before jumping back to Jamie's modern investigations. Because of this structural style, there is no separate chronological reading order that works better than publication order.
What to Know Before You Start
Before you dive into the books, it is helpful to keep a few tips in mind to get the most out of your reading experience:
- Standalone Appeal: Each book features a self-contained archaeological mystery that is fully resolved by the final page. You won't be left hanging on a massive cliffhanger between books, meaning you can technically read them out of order if you happen to pick one up at a used bookstore. However, reading them in order is strongly recommended to follow Jamie and Sarah's relationship development.
- The Author's True Identity: James Douglas is the pen name of Douglas Jackson, a highly respected Scottish historical fiction author known for his Rome-based novels. Jackson uses the pseudonym for his contemporary thrillers. His background as a journalist and historical researcher shines through in the detail he brings to the WWII and ancient history segments.
- Tone and Style: The series is an ideal choice for fans of action-adventure thrillers like those written by Dan Brown, Clive Cussler, James Rollins, and Steve Berry. It successfully blends historical facts regarding Nazi plunder, occult interests, and military history with fast-paced, modern conspiracy plots.
