After Martin Somerville, a pharmacologist and Rockport-Meier employee, becomes curious about the source of the company director's art collection, he is dismissed from the company and later disappears without a trace. Adam Locke, a young professor and former student of Reggie Crawford, is enlisted to join the professors at his own risk, and he serves as the narrator of the story. Crawford's meticulously recorded diskettes, which explain the background of the group's adventures, are passed on to Locke to bring him (and us, the readers) up to speed. Anticipating that he would be a target, Crawford knew that his tapes would provide those who survived him with the essential information to move toward resolving the mystery.
