Sam Fortune and the Wisdom of the Ancients

It's 1925, and Sam Fortune, a down-on-his-luck adventurer, has just been asked to help track down a missing history professor. Intrigued by the huge reward offered for the professor's safe return, he teams up with his adopted daughter Nellie and a young sailor named Griff, and sets out to find him...but all he finds is trouble. Now caught up in a dangerous quest for an enormously valuable treasure, Sam and his friends battle their way through London alleys, ancient castles, and underground chambers, risking everything in pursuit of the reward...and the secret behind the greatest collection of ancient knowledge the world has ever seen.
