At the first opportunity, Nick called upon the blind millionaire, by appointment. He was not able, however, to give any definite or compelling reasons for his attitude, and, as he had feared, all of his arguments were in vain.

Baldwin admitted the truth of many of the detective’s points, but they had no weight with him. He plainly showed his knowledge of Grantley’s past unscrupulousness, but declared that he was willing to take whatever risks might be involved.

Nothing could shake his conviction that the surgeon would not dare to injure him in any way, and he returned repeatedly to Grantley’s own strongest argument—namely, that the vivisectionist had, in the huge fee at stake, the greatest possible incentive to do his best.

Finally, the millionaire thanked Nick for his interest, but announced his intention of submitting to the operation at the time appointed.

“I’d give millions, if necessary, to any one who could give me back my sight, Mr. Carter,” he said, as Nick rose to go; “and the character and previous record of Doctor Grantley are matters of supreme indifference to me. If he were guilty of all the crimes in the penal code, I should still put myself into his hands, for every conceivable consideration of self-interest would operate to make him hold me sacred and to give me the utmost of which he is capable.”

As yet, Nick had nothing to show for his pains, but he did not give up.

CHAPTER XV.
MADDENING SUSPENSE.

The detective gave hurried orders to his assistants and set them to work on another investigation into Grantley’s past, with a view to ascertain, if possible, the surgeon’s experiences in Wall Street.

Unfortunately, nothing of any importance was unearthed.

It was learned that Doctor Grantley had speculated heavily at one time, years before, and was supposed to have been unlucky in some of his investments, but the exact facts could not be obtained.
