Griswold watched his halting progress, then sought the young doctor once more.

“It’s important that this man should be able to talk as soon as possible—if he’s ever going to,” he said. “If you desire to consult with any one, no matter what his price, do so, and I’ll be responsible. You may also look to me for your fee, and I wish you would get the best of trained nurses you can procure—one whose discretion you can rely upon. While you are with the patient, listen carefully for anything he may say, and make a note of it, whether it seems delirious or not. Request the nurse to do the same, and see that I’m notified by phone as soon as Cray is able to be questioned for five minutes.”

“Very well, Mr. Griswold.”

“One thing more. If the patient should become lucid at any time, and you or the nurse should have reason to believe that he may lapse into this same condition in a few minutes, ask him just one question and jot down his answer.”

“And that question?”

“Ask him who is responsible for his injuries—who struck him down.”

Doctor Lord agreed to do so if the opportunity offered, and, after coming to that understanding, the millionaire reëntered his waiting car.

“New York,” he ordered, giving Nick Carter’s address.
