Willett, who brought Charles Ward into the world and had watched his growth of body and mind ever since, seemed frightened at the thought of his future freedom. He had had a terrible experience and had made a terrible discovery which he dared not reveal to his sceptical colleagues. Willett, indeed, presents a minor mystery all his own in his connexion with the case.

He was the last to see the patient before his flight, and emerged from that final conversation in a state of mixed horror and relief which several recalled when Ward’s escape became known three hours later. That escape itself is one of the unsolved wonders of Dr. Waite’s hospital.

A window open above a sheer drop of sixty feet could hardly explain it, yet after that talk with Willett the youth was undeniably gone. Willett himself has no public explanations to offer, though he seems strangely easier in mind than before the escape. Many, indeed, feel that he would like to say more if he thought any considerable number would believe him.

He had found Ward in his room, but shortly after his departure the attendants knocked in vain. When they opened the door the patient was not there, and all they found was the open window with a chill April breeze blowing in a cloud of fine bluish-grey dust that almost choked them. True, the dogs howled some time before; but that was while Willett was still present, and they had caught nothing and shewn no disturbance later on.

Ward’s father was told at once over the telephone, but he seemed more saddened than surprised. By the time Dr. Waite called in person, Dr.

Willett had been talking with him, and both disavowed any knowledge or complicity in the escape. Only from certain closely confidential friends of Willett and the senior Ward have any clues been gained, and even these are too wildly fantastic for general credence. The one fact which remains is that up to the present time no trace of the missing madman has been unearthed.

Charles Ward was an antiquarian from infancy, no doubt gaining his taste from the venerable town around him, and from the relics of the past which filled every corner of his parents’ old mansion in Prospect Street on the crest of the hill. With the years his devotion to ancient things increased; so that history, genealogy, and the study of colonial architecture, furniture, and craftsmanship at length crowded everything else from his sphere of interests. These tastes are important to remember in considering his madness; for although they do not form its absolute nucleus, they play a prominent part in its superficial form.

The gaps of information which the alienists noticed were all related to modern matters, and were invariably offset by a correspondingly excessive though outwardly concealed knowledge of bygone matters as brought out by adroit questioning; so that one would have fancied the patient literally transferred to a former age through some obscure sort of auto-hypnosis. The odd thing was that Ward seemed no longer interested in the antiquities he knew so well. He had, it appears, lost his regard for them through sheer familiarity; and all his final efforts were obviously bent toward mastering those common facts of the modern world which had been so totally and unmistakably expunged from his brain.
