Here was an unexpected discovery. It was a miracle of miracles. There had been no search for the missing man. There was no hue and cry. Lord Castleton, like most Englishmen of an inquiring turn of mind, wanted to see the sights of New York, in order to record his impressions when he returned home. He had employed the services of one of the sharpest detectives in the city to show him round, and by a miracle he had discovered and probably saved the life and reason of his old friend.

In an instant the officer of police understood and grasped the situation. Once given the clew, and difficulties melt into thin air. It took very little time to procure an order for the release of the unfortunate Englishman, and before night-time the medical proprietor of the fashionable madhouse was safely lodged in a New York prison, and available for evidence on the subject of Mrs. Senator Clutterbuck, and, more important still, the safety and whereabouts of the unfortunate child Ronny.

At one time it appeared as if the troubles of Frank Onslow would end in an unsuspected manner. The drama was becoming a tragedy. He was released, it is true; he was safe once more. The discovery of his child was now more than probable. The discomfiture of his enemy, Mrs. Clutterbuck, was nearly complete, but the reaction after all this mental and physical strain nearly cost Frank Onslow his life. The strongest men break down at a given point, and now it was Frank’s turn to succumb.

Once outside the asylum he appeared to be more insane than when he was in it. He wanted to face his enemy, and swore he would kill her. He pleaded to scour New York for the boy. He rushed off to the telegraph office to inform the wretched mother that he was true, and she might yet hope, but the strain was too much for even his strong constitution, and when he had placed in the hands of the detective every atom of information he possessed, and had almost imperatively been urged to leave the work of discovery to the hands of others, he went back reluctantly to his hotel, half-hysterical with excitement, but utterly dead beat. Lord Castleton found his friend, next morning, raging in the delirium of fever. At one time he cried piteously for Fenella, and kissed the pillow where he believed she had rested; in another instant he was twisting the bedclothes into a knot and imagined he was strangling Mme. de Vigny. In the intervals he was sobbing, as if his heart would break, “Ronny, Ronny, my boy, my boy!”

No woman could have tended a sick man with greater devotion than did Lord Castleton. Night and day he never left his friend except to receive reports from the head office of the detectives, who once more proved themselves the finest officers in connection with any police service in the world. By constant care and devoted nursing the crisis was past. Reluctantly the doctors gave the permission for a move to be made, and on a certain bright morning Lord Castleton, with the aid of an invalid carriage, took his worn and wasted friend down to the docks, where he had secured berths for England on board one of the fastest steamers of a prominent line. The journey to the sea seemed to revive the patient. As yet he had not been allowed to see any friends save Castleton, or to ask any questions. But the mists gradually disappeared from his eyes, and a smile of happiness played on his wan features.

“God bless you, old boy,” he said to Castleton as they drove slowly to the ship. “God reward you. Never did man find a truer friend. I should have been under the turf, old man, if it had not been for your tender care.”

Castleton was anxious not to excite his friend too much. For the day was not over, and he knew that the drama of it was not yet complete.

On board they found Jacynth, who had been as loyal to his trust as Castleton.

The two men, when they met, whispered for a second to one another, and there was a look of distressed suspense on Frank Onslow’s face.

“Is all well?” whispered Castleton.
