“Mason, the injured man recently sent here on your order,” the note read, “has most mysteriously disappeared from the hospital. Doctor Bolt, the surgeon detailed, at your request, to take charge of the case, decided to watch the man for the night, and so my attendants were withdrawn. The surgeon must have fallen asleep, for in half an hour’s time he came running to my door shouting that Mason had escaped. As soon as possible I visited the room from which the man had disappeared and found the window sash raised.

“There were many footprints in the soft earth under the window—the footprints of men in coarse shoes—and a smear of blood on the window casing disclosed the fact that the injured man had been drawn through the opening. It is quite evident to me, therefore, that the man was carried from the room by some one interested in the case, to which Doctor Bolt only indirectly referred when talking with me. Your presence at the hospital is earnestly requested.”

The note was signed, as stated, by the night matron. Scarcely had Havens finished the reading of it when he heard some one stumbling through the darkness, and the next moment Surgeon Bolt, looking crestfallen and excited, stood before him, like a schoolboy anticipating censure.

“It’s the strangest thing I ever saw!” exclaimed the surgeon. “Mindful of your interest in the man, I decided not to trust him to the care of any of the hospital attendants to-night. After doing what I could for him, I sat down by the side of his bed to read and smoke. My mind was never clearer or farther from drowsiness than it was at that time.”

“Yes,” Havens said, in a sarcastic tone, “the result seems to indicate that you were wide awake!”

“I tell you,” almost shouted Bolt, “that I was stupefied by the injection of chloroform or some other anesthetic into the room!”

“How could that be possible?” demanded Havens.

“I don’t know!” wailed Bolt. “I certainly do not know! The window was closed when I looked at it last, just before I became unconscious. When I came to my senses to find the bed empty, a cold wind was blowing on my face. That is undoubtedly what awakened me. Only for that I might have slept myself to death!”

While the two talked together a watchman from the office building approached and informed Havens that a lady was waiting there to see him.
