My name is Henry Sinclair, Baron of Roslin, Lord Chief Justice of Scotland and Admiral of the Seas. I also held the titles of Earl of Orkney and Lord of Shetland and master of Roslin Castle. The king of Norway invested me as Jarl of the Orkneys ranking next to the Roy house before all the Scandinavian nobility. I am both of Scottish and Norwegian nobility. I lived between the years 1345 and 1400 but live I did! I had a full robust life filled with adventure and daring! I lived more in my fifty-five years than any fifty men such as you!
My greatest secret is that I was the grandmaster of the Knights Templar. I, and I alone, held the secret of where the wealth of the Knights Templar was secreted so the king of France and the Pope could never find it after their treachery ended the lives of most of my brothers, decades before my birth.
My greatest adventure was moving this treasure and the religious artifacts that were hidden under their noses out of Europe and to the new world where it would be forever out of their reach. Your Oak Island became their new home. I learned of the new world from my Scandinavian relatives, the Vikings. I will tell you this great adventure from beyond the grave. From when we amassed the treasure, during the second Crusade, when we held the Temple Mount in Jerusalem for eleven years, until the tale's end in the year of our lord, 1386. Join me now on the greatest adventure and mystery ever, the Oak Island mystery.
