“Be ready to slip out, sir. I’ll follow, but this brute must not come. He must be locked in this place.”

“Yes; I understand,” groaned the old man, who was trembling, and looked a pitiable spectacle, with his white face, and his evening dress covered with lime and whitewash.

“Down, Bruno! Watch?” roared George, as he unlocked the outer door and drew out the key.

The dog growled but obeyed, the door was opened enough to let the lawyer pass through, and as he did the cries without sounded terrible, and nearly maddened the dog, who once more sprang at the door. But George seized him by the collar, dragged him back, there was a brief struggle, and he managed to hurl him into a corner, and slip through the door, locking it as he banged it to, and then placing the key in his pocket, he ran through the baize door to where a terrible struggle was going on between Saul Harrington and the doctor, while Mrs Hampton and Gertrude were making the place echo with their appeals for help.

Stirred to the heart by the position in which he saw his old friend, Mr Hampton had rushed to his assistance, but Saul Harrington in his wild fit of delirium made naught of their joint efforts, and was in the act of dashing them off as George Harrington appeared at the study door, and confronted the wretched maniac, who leaped at him with a howl that did not seem human.

There was a desperate struggle for a minute, during which George strove hard to throw Saul Harrington, who fixed his teeth in George’s collar as he grasped him like a vice; and it was only by a sudden wrench that the young man saved his throat. He leaped here and there, and at last, in a despairing effort, George threw all his strength into the lifting of his adversary, but overbalancing himself in the act, they both fell with a crash, and Saul leaped up and darted through the door.

Sick and giddy, George Harrington rose painfully to his feet, and staggered to the door, for a wild cry rang through the house.

“Gertrude!” he groaned, and he made for the passage, only to be driven back by Saul, who passed him and tore through the baize door, which banged to behind him.

“Can you help?” said George hoarsely. “We must master him somehow.”

“Yes, yes,” came from the two old men; and together they followed him as he laid his hand upon the door, panting heavily for breath.
