They all busied themselves with him, crowding round his seat, but Wenk remained in his chair. He was struck by the connection between his little experience and the old gentleman’s attack of faintness. Were they indeed connected? He felt as if he were responsible for the Professor’s collapse. It seemed as if he had subconsciously come into conflict with him, and that this fainting-fit was the result of their struggle. He was considering how he could help him. Then he felt in his waistcoat-pocket and brought out his little bottle of smelling-salts. He took the stopper out and handed it across, saying, “Perhaps these salts may be of use? I have just ...” but he was surprised to find that the old gentleman had already departed. His earlier misgivings returned. He rose quickly and pushed his way through the crowd. He wanted to follow the man and bring him back. Someone suddenly stopped him, saying something incomprehensible, as if he, Wenk, were responsible for the Professor’s condition; but Wenk’s hand went to the revolver in his breast-pocket. Cara Carozza advanced towards him; he pushed her hastily aside, dragging the other with him. Then with his disengaged hand he violently wrenched himself free of his assailant’s grip, and hurried to the corridor which formed the dimly lighted side-entrance. He heard footsteps behind him as he entered it, hastened forward, closed the door behind him after passing through, and soon gained the side street where the motor-cars were waiting. By the light of a lantern he saw the old gentleman, bent and bowed no longer, but with hasty and powerful stride about to enter a car. He saw his own chauffeur drawing up to the kerb, and called to him in a low voice, “Follow that car!” They flew after it. It was a large and powerful car, but as it was still early in the evening, there was a good deal of traffic, and it could not travel at its full speed, consequently they were close behind it. They were soon caught up in a stream of cars and taxicabs coming from one of the theatres, so that Wenk could follow quietly and without exciting suspicion right to the Palace Hotel. The Professor’s car stopped in front of it, and before Wenk’s car came to a standstill he saw the other enter the vestibule hastily. He gave a fleeting glance round. Wenk hastened after him, but happened to be caught in the stream of those entering, who hid him from sight. He saw the Professor rapidly open and read a telegram at the hotel bureau, and while he was reading it Wenk had time to select a favourable spot for observing him. Thus he saw that the old gentleman, raising his eyes from his telegram, gave a furtive glance round, then went quickly to the lift, opened the door and disappeared within it; but Wenk had noticed that there was a lift attendant sitting inside. He waited till the light signalled where the lift had stopped, and saw it was on the first floor; then he rang for it to descend.
