"To think of a holdup on this street!"

"There was a carriage, I'm sure."

And then the policeman was flashing his lantern about among them, as he bade them stand back, and the rescuer, who looked like a workman in his Sunday clothes, looked up, from the place where he knelt, supporting the head and shoulders of the unconscious man, and said:

"Gentlemen, this is Mr. Brierly, Robert Brierly of 1030 C—— Avenue; the Myers house, only two blocks away. He must be taken home at once. Has any one a cot? No, he must be carried." For at the name of the Myers house, a gentleman had proffered his carriage at once. "And, officer, call up help. If possible, that cab must be traced. Send to the stand just above and find out what cabs have left it within the past quarter hour. Let some one go ahead and bring Doctor Glessner from just opposite 1030. He's at home."

"How did it happen?" asked Mr. Myers, two hours later, when the injured man—his wounded head carefully dressed—lay, still dazed and in a precarious condition, in his darkened room, with a trained nurse in attendance.

Ferrars having seen his friend in his own room, and in the hands of the doctors, had not waited for their verdict, but had set off to put in motion his plan for hunting down the would-be murderer, and he had but now returned, full of anxiety for the fate of the sufferer.

"How did it happen? After all our precautions, too!"

"It's easy to tell how it happened," replied Ferrars with some bitterness. "It happened, first, because the enemy outwitted me, in spite of my cordon of guards; and, second, because Brierly lost patience and exposed himself."

"But how?"
