Grantley’s skill had made a bungling job impossible, despite the highly dangerous nature of the inexcusable operation which had been performed upon her.

Alma owes her life to Nick Carter twice over, as a matter of fact, for the detective was not only instrumental in halting the operation and rushing her to the hospital at the earliest possible moment, but also furnished the money which enabled her, later on, to go to the Adirondacks, where she made a complete recovery from her lung trouble.

Grantley, Siebold, and Hoff were locked up that night. The six young physicians who had been Grantley’s disciples had left the house before the climax, after the flesh wound which Patsy had inflicted on one of them had been dressed. The nurse had taken “French leave” as soon as her employer and his two companions started for the cellar. All of them were rounded up, however, despite the difficulties involved.

Nick was usually opposed to newspaper sensations, but in this instance he encouraged the newspapers to make as much as they could of the arrests and the shocking practices which had led up to them.

CHAPTER XII.
A SURPRISING DEVELOPMENT.

“You say that Doctor Hiram Grantley has offered his services to J. Hackley Baldwin? What do you mean?”

These two startled questions were put by Nick Carter to a handsome, impressive-looking man of the most polished professional aspect.

The scene of the interview was the detective’s study, and the gray-haired man in eyeglasses, with whom he was closeted, was Doctor Delos Vanderpool, physician to many of the most exclusive families in the city, and, more particularly, the family practitioner of J. Hackley Baldwin, the blind multimillionaire.

“I mean exactly what I say, Mr. Carter,” Doctor Vanderpool replied gravely. “There is no room for mistake, unfortunately. Grantley, the surgeon who has been shown up so completely—thanks to you—in connection with his reckless and shocking experiments on living human beings, has had the effrontery to approach Mr. Baldwin and offer to perform an operation on his eyes.”

The detective’s attitude relaxed as a result of this explanation. He knew as well as anybody that the powerful millionaire had been totally blind for years, and had spent hundreds of thousands of dollars and submitted to numerous operations in vain, in an attempt to recover his sight.
