The Unknown Seven

This edition has been fully restored with modern typesetting, custom cover design. In a fog-bound New York, investigator Kingdon Cole shadows the reclusive Professor Carmody, trying to learn what happened to the missing Malcolm Reeves. His vigil is shattered when a woman in a luxurious limousine calls him by name and leads him, blindfolded, into a hidden world of private elevators, sealed corridors, and a top-floor suite inside the respectable-looking Security Building. Astonishingly well informed, she knows his habits, his successes, and the secrets surrounding Carmody, and she warns that Reeves may already be dead and that the case reaches far beyond a single disappearance. Calling herself Miss Brown, she tries to lure Cole away from the investigation, first with emotional pressure and then with money offered by seven masked men in a secret meeting room. Cole refuses to be bought. Instead, he pushes deeper into the mystery, discovering that the building's bland exterior conceals the headquarters of the Unknown Seven, a powerful hidden organization. His search takes him to Dr. Latham's house, where a hunchbacked patient, a stolen key, and Latham's own cool menace hint at even darker forces at work. As the dead body of Reeves is confirmed and the hidden chambers close in around him, Cole finds himself trapped in a conspiracy of surveillance, murder, and deception.
