The knocking was repeated a little louder, and finally a voice called: "Mr. Jack!"

It was one of the house men—Mr. Moore recognized the fellow's voice. He came near to bursting a blood vessel in an endeavor to scream "come in" through the stifling gag. After a moment the man knocked again, quite loudly and again called the boy's name. Receiving no reply he turned the knob, and at the same instant a sudden recollection filled the tutor anew with numbing terror—he had, himself, locked the door behind him when he had entered the room.

He heard the servant try the door several times and then depart. Upon which Mr. Moore swooned.

In the meantime Jack was enjoying to the full the stolen pleasures of the music hall. He had reached the temple of mirth just as Ajax's act was commencing, and having purchased a box seat was now leaning breathlessly over the rail watching every move of the great ape, his eyes wide in wonder. The trainer was not slow to note the boy's handsome, eager face, and as one of Ajax's biggest hits consisted in an entry to one or more boxes during his performance, ostensibly in search of a long-lost relative, as the trainer explained, the man realized the effectiveness of sending him into the box with the handsome boy, who, doubtless, would be terror stricken by proximity to the shaggy, powerful beast.

When the time came, therefore, for the ape to return from the wings in reply to an encore the trainer directed its attention to the boy who chanced to be the sole occupant of the box in which he sat. With a spring the huge anthropoid leaped from the stage to the boy's side; but if the trainer had looked for a laughable scene of fright he was mistaken. A broad smile lighted the boy's features as he laid his hand upon the shaggy arm of his visitor. The ape, grasping the boy by either shoulder, peered long and earnestly into his face, while the latter stroked his head and talked to him in a low voice.

Never had Ajax devoted so long a time to an examination of another as he did in this instance. He seemed troubled and not a little excited, jabbering and mumbling to the boy, and now caressing him, as the trainer had never seen him caress a human being before. Presently he clambered over into the box with him and snuggled down close to the boy's side. The audience was delighted; but they were still more delighted when the trainer, the period of his act having elapsed, attempted to persuade Ajax to leave the box. The ape would not budge. The manager, becoming excited at the delay, urged the trainer to greater haste, but when the latter entered the box to drag away the reluctant Ajax he was met by bared fangs and menacing growls.

The audience was delirious with joy. They cheered the ape. They cheered the boy, and they hooted and jeered at the trainer and the manager, which luckless individual had inadvertently shown himself and attempted to assist the trainer.

Finally, reduced to desperation and realizing that this show of mutiny upon the part of his valuable possession might render the animal worthless for exhibition purposes in the future if not immediately subdued, the trainer had hastened to his dressing room and procured a heavy whip. With this he now returned to the box; but when he had threatened Ajax with it but once he found himself facing two infuriated enemies instead of one, for the boy had leaped to his feet, and seizing a chair was standing ready at the ape's side to defend his new found friend. There was no longer a smile upon his handsome face. In his gray eyes was an expression which gave the trainer pause, and beside him stood the giant anthropoid growling and ready.

What might have happened, but for a timely interruption, may only be surmised; but that the trainer would have received a severe mauling, if nothing more, was clearly indicated by the attitudes of the two who faced him.


It was a pale-faced man who rushed into the Greystoke library to announce that he had found Jack's door locked and had been able to obtain no response to his repeated knocking and calling other than a strange tapping and the sound of what might have been a body moving about upon the floor.

Four steps at a time John Clayton took the stairs that led to the floor above. His wife and the servant hurried after him. Once he called his son's name in a loud voice; but receiving no reply he launched his great weight, backed by all the undiminished power of his giant muscles, against the heavy door. With a snapping of iron butts and a splintering of wood the obstacle burst inward.

At its foot lay the body of the unconscious Mr. Moore, across whom it fell with a resounding thud. Through the opening leaped Tarzan, and a moment later the room was flooded with light from a dozen electric bulbs.

It was several minutes before the tutor was discovered, so completely had the door covered him; but finally he was dragged forth, his gag and bonds cut away, and a liberal application of cold water had hastened returning consciousness.

"Where is Jack?" was John Clayton's first question, and then; "Who did this?" as the memory of Rokoff and the fear of a second abduction seized him.

Slowly Mr. Moore staggered to his feet. His gaze wandered about the room.
