At two-thirty in the morning of June 6, 1998, Whitley Streiber was awakened by somebody knocking on his hotel room door. A man came in, and everything he said was life-altering. This is the unsettling and ultimately enlightening narrative of what happened that night. Strieber was never really sure who this strange and knowing visitor was--a "Master of Wisdom"? A figure from a different realm of consciousness? A preternaturally intelligent being? He called him the Master of the Key. The one thing of which Strieber was certain is that both the man and the encounter were real.
