Associated with Art Bell:

In the pre-dawn hours of June 6, 1998, Strieber was reportedly visited in his Toronto hotel room by a mysterious but apparently human man, who delivered an unsolicited lecture covering various subjects from spirituality to the environment. The man gave no name, but Strieber has taken to referring to him as the "Master of the Key." Strieber first reported the visit in his online journal in 1998 and later gave a more complete account in his self-published book The Key (2001). Skeptics have pointed out that The Key and the 1998 journal entries give very different (not contradictory, but largely non-overlapping) accounts of what the man said.

Before publishing The Key, Strieber co-authored The Coming Global Superstorm (1999), a book about the possibility of rapid and destructive climate change, with Art Bell. He has said that it was based largely on things the Master of the Key had told him about the environment. The book served as the inspiration for the disaster film The Day After Tomorrow (2004), and Strieber later wrote a novelization of that movie.
