The actress agreed to this, and Nick Carter took leave of her, after promising to apprehend Grantley as soon as possible and to keep her informed of the progress of his search.

Before he left the hotel he had a short talk with Doctor Lightfoot, which gave promise of a more intelligent handling of the case, aside from the benefit which Helga Lund had already derived from her frank talk with the sympathetic detective.

The man hunt could now begin in New York City, instead of at Ossining, and, since the preliminaries could be safely intrusted to his assistants, Nick decided to comply with Warden Kennedy’s urgent request and run up to the prison to see what he could make of the keeper’s condition.

CHAPTER IV.
STRONGER THAN BOLTS AND BARS.

The great detective set his men to work and called up the prison before leaving New York. As a result of the telephone conversation, the warden gave up the search for the fugitive in the neighborhood of Ossining.

Ossining is up the Hudson, about an hour’s ride, by train, from the metropolis. It did not take Nick long to reach his destination.

He found Warden Kennedy in the latter’s office, and listened to a characteristic account of Doctor Grantley’s escape, which—in view of the fugitive’s subsequent appearance at the theater—need not be repeated here.

Bradley, the keeper, was still unconscious, and nobody seemed to know what was the matter with him. Nick had a theory, which almost amounted to a certainty; but it remained to confirm it by a personal examination.

The warden presently led the way to the prison hospital, where the unfortunate keeper lay. No second glance was necessary to convince the detective that he had been right.

The man was in a sort of semirigid state, curiously like that of a trance. All ordinary restoratives had been tried and had failed, yet there did not appear to be anything alarming about his condition.
