He understood why the story had startled him, too. "Mind Master!" Anything that had to do with the human brain interested him mightily now, for he knew to what grim uses it could be put at the hands of a master scientist. Around his own head, safely covered by his hair unless someone looked closely, and even then they must needs know what they sought, was a thin white line. It marked the line of Caleb Barter's operation on him that terrible night in the African jungles, when his brain had been transferred to the skull-pan of an ape, and the ape's brain to his own cranium. Any mention of the brain, therefore, recalled to him a very harrowing experience. It was little wonder that he shuddered. Ellen noticed his agitation. "What is it, dearest?" she asked softly, placing her hand in the crook of his arm. - - - He was about to answer her, desperately trying to think of something to say that would not alarm her, when their taxicab, with a sudden application of the brakes, came to a sharp stop. Bentley noticed that they were at the intersection of Twenty-second Street and Fifth Avenue. The lights were still green, but nevertheless all traffic was halted. And for a strange reason. From the west door of the Flatiron Building emerged a grim apparition of a man. His body was scored by countless bleeding wounds which looked as though they had been made by the fingernails of a giant. The man wore no article of clothing except his shoes. Apparently, his clothing had been ripped from his body by the same instrument which had turned his body into a raw, dripping horror. The man staggered, half-running, at times all but falling, toward the traffic officer at the intersection. As he ran he screamed, horrible, babbling screams. His lips worked crazily, his eyes rolled. He was frightened beyond the comprehension of ordinary mortals. His screams began and ended on the high shrill notes of utter dementia, and as he ran he pawed the air with his bleeding hands as though he fought out on all sides against invisible demons seeking to drag him down. "Oh, my God!" said Ellen. "Even here!" What had caused her to speak the last two words? Did she also have a premonition of grim disaster? Did she also feel, deep down inside her, as Bentley did, that the nightmare through which they had passed was not yet ended? Bentley now sat unmoving, his eyes unblinking, as he saw the naked man stagger over to the traffic officer. The color drained from his face. He looked at his watch. It was exactly noon. Even without further consideration Bentley knew that this gruesome apparition had some direct connection with the newspaper story he had just read. - - - Unobtrusively, trying to make it seem a preoccupied action, he folded the newspaper again and thrust it down at the end of the seat cushion. But Ellen was watching him, a haunting fear gradually coming into her eyes.
