It had gone midnight when we climbed up from our visit to the hold. As we returned to the elevator a door opened in the corridor ahead and two men, one in seamen's uniform, stepped out. between them sagged a third man, knees buckling, head sunk on his breast. A monstrous hissing rolled towards us and ceased as the door clanged shut. I would have passed by had I not recognised Riley. Hopper and Melchett, side-stepping, walked on.
