A former military colleague of Jonathan Payne and David Jones has discovered what he thinks is a Nazi bunker filled with crates of unknown treasures in Bavaria. Since Payne and Jones have past experience with historical lost treasures, he contacts them for assistance. But they soon learn it is not Nazi loot that's been uncovered when some of the crates are stamped with the black swan insignia associated with King Ludwig II. The legend goes that the murdered king had been amassing large quantities of gold and jewels to build an ostentatious castle the likes never before seen. But no evidence has ever been found to substantiate those claims -- until possibly now.

Calling in a friend who's an expert in German and Bavaria history makes for an interesting lesson in history as the four men soon find themselves in a life-or-death situation to find out the truth of the treasure that's been found and how it relates to Ludwig and his quest.

With an elaborate and fascinating tale of history and long- lost treasure, this pulse-pounding action-adventure thriller will keep readers entertained until the fascinating conclusion.
