Bryan turned his attention to the girl in an effort to quicken her return to consciousness. Shortly her eyes opened--then flared with recollection. She glanced swiftly about her, fright twisting at her face. In the next instant she saw her fallen escort and seemed to realize for the first time that Bryan was a stranger. She went quickly to the other man and lifted his head. "Tom!" she cried. "Tom! What is the matter?" Horror grew in her voice. "Why don't you answer me?" Empty eyes that looked sightlessly into the night. Slack gaping lips that did not move. The girl turned to Bryan with an expression of bewildered grief. "How ... how did this terrible thing happen?" Bryan hesitated. What he had experienced now seemed too wildly improbable to discuss. The very improbability of it could only add to the girl's suffering. And for a reason he did not fully understand he wanted to keep to himself the knowledge of that strangely lovely apparition whose name, it appeared, was Leeta. He shook his head. "I'm afraid I don't know." The girl's control seemed to break. She covered her face with her hands, convulsive sobs shaking her. Bryan waited helplessly, with a feeling of guilt. In another moment, over the muffled sobbing, he heard the sound of approaching feet. A flashlight beam bobbed into view up one of the radiating walks, and presently Bryan was able to make out the blue-clad running figure of a patrolman. "What's going on?" the patrolman demanded. "I heard a scream." He moved his flashlight beam from the girl and the prostrate man, to Bryan. He added in surprise, "You here, Terry?" Bryan nodded a greeting, recognizing the other now as Pat Mulvaney, a park officer. "This man seems to be hurt, Pat. We'd better get him to a hospital." Mulvaney bent over the sprawling figure, then returned to Bryan, speaking low-voiced. "Hurt ain't the word for it, Terry. This case is like the other ones we found in the park. And it would have to happen tonight. Olson was supposed to be on duty at this end, but he sprained an ankle. We're short-handed, what with the Department being on a budget." With the girl tearfully following, Bryan and Mulvaney carried the stricken man to a call box, where Mulvaney telephoned his report and requested that an ambulance be sent. Bryan was asked to accompany the girl to headquarters, in a squad car, for questioning. * * * * * It wasn't until shortly before dawn that Bryan reached his room and began undressing for bed. He examined his bare shoulder in a mirror. There was a reddish patch on the skin, the size of a half-dollar piece, where the sharp snout of the mosquito-man had pierced him. The mark convinced him further that the whole thing had been no mere hallucination. He felt no pain--but his body seemed faintly, oddly feverish. And he had a light-headed feeling that could not have been entirely due to tiredness.
