In a slightly louder tone John repeated his remark. This time the vacant expression faded slowly from the large, pale eyes, and Andrew Henderson moved his head weakly.

Seeing the indication of consciousness, John carefully measured out a dose of medicine, and, stooping over the pillows, passed one arm under his uncle's neck.

Andrew Henderson submitted without objection, but as his head was raised and the medicine held to his lips, he seemed suddenly to realize the position, to comprehend that it was his nephew who leaned over him. With a spasmodic movement he turned towards John, his lips twitching with some inward and newly aroused excitement.

"The Book, John!" he said, sharply—"the Book!"

John remained quite composed. With a steady hand he balanced the spoon of medicine that he still held.

"Your medicine first, uncle," he said, quietly. "We'll talk about the Book after."

But the old man's calm had been disturbed. With unexpected strength he raised one thin hand and pushed the spoon aside, spilling the contents on the bed.

"How can I leave it?" he exclaimed. "How can I go and leave the Book unguarded?" Again his lips twitched and a feverish brightness flickered in his eyes as they searched his nephew's face.

"When I go, John," he added, excitedly, "the Book may be in your keeping for hours—perhaps for a whole night. I know the Arch-Councillor will answer my summons immediately; but it is possible he may be delayed. It may be the ordination of the Unknown that I should Pass before he arrives. If this is so, I want you to guard the Book—but also I want you to guard my dead body. Let no one touch it until he comes. The key of the safe is here—" He fumbled weakly for the thin chain that hung about his neck. "No one must remove it—no one must touch it until he comes—" His voice faltered.

With a calm gesture John forced him back upon the pillows, and quietly wiped up the medicine.
