The young man was evidently in a tremendous hurry, and as soon as the ferryboat bumped into the slip he was at the gate and was the first one ashore. He beckoned to one of the alert taxicabmen, and without waiting to have the vehicle brought to him, ran to it and leaped inside.

"Do you know where the Vanderslip Building is?" he questioned abruptly.

"Yes, sir."

"Then take me there with all possible speed."

"Yes, sir."

The door slammed, the taxi driver mounted to his seat, and off the taxi started at the best rate of speed the driver could attain. The young man sank down among the cushions and buried his chin in his hands.

His face, normally a handsome one, was now wrinkled with care, his hair was disheveled, and he looked as if he had lost much sleep. At times his mouth twitched nervously and he clenched his fists in a passion which availed him nothing.

"To think that she is guilty!" he muttered. "It is horrible! Horrible!" And then his whole frame shook as if with the ague. Twice he started up, to see if he had not yet arrived at his destination. But the drive was a long one, and to him, in his keen anxiety, it appeared an age.

"If he is away—out of town—in Europe, or on some case which he cannot leave, what am I to do?" he murmured. "I've pinned my whole faith on him."

Presently there was a jar, and the taxicab came to a halt in front of a large office building. The young man gave one look, and, before the driver could get down, had the door open and was on the pavement. "Here you are," he said and thrust a dollar bill into the fellow's hand. Then he crossed the broad pavement and was lost to sight in the corridor beyond.
