The man understood, but was naturally slow to risk a sharp collision merely at the order of an excited gentleman in evening dress. He stopped quickly enough, but, by the time his help was available, pursuit was hopeless; the one thing Curtis could do he had done--while running up the street he had deciphered the number of the car, X24-305.
Before Curtis rejoined the dazed hall-porter a small crowd had gathered, and it was difficult to get near the body lying on the curb. A man picked up an overcoat, and Curtis, cool and clear-headed now, took it, and appealed to him, if he knew where the nearest doctor lived, to run thither at top speed. The man obeyed him instantly.
"Meanwhile, let me see to the poor fellow," he said. "I am not a doctor, but I know enough about wounds to say whether those scoundrels have killed him or not."
The throng yielded to an authoritative voice, and some of the more sensible bystanders formed a ring, thus securing a semblance of light and air around the prostrate man. Curtis struck a match, and it needed no second glance to learn that the stranger's lung had been pierced by an almost vertical thrust; indeed, he was already dying. The poor lips, from which blood and froth were bubbling, strove vainly to articulate words which, in the prevalent hubbub of alarm and excitement, it was impossible to distinguish. A policeman came, and, as a traffic station for the precinct happened to lie within a couple of doors, the moribund form was carried in, and placed on a stretcher kept there for use in emergency.
A doctor was soon on the spot, but he arrived just in time to record the last flicker of life in the tortured eyes. Then, as one in a dream, Curtis gave the policeman the details of the crime, the name of the chauffeur, and the number of the car, his testimony being borne out to some extent by the hall-porter, and, so far as the car was concerned, by the sharp-eyed driver of the taxi. His own name and address were taken, and a police captain and a couple of detectives, called to the scene by telephone, thanked him for his alertness in securing valuable clews, not only in regard to the car and chauffeur but also in describing the features, figure, and dress of one of the criminals.
