Again she hesitated, as though doubting the wisdom of further speech; but a brief scrutiny of Cairn's face, with deep anxiety to be read in his eyes, determined her to proceed.

"I had been asleep, and I must have been dreaming, for I thought that a voice was chanting, quite near to me."

"Chanting?"

"Yes—it was horrible, in some way. Then a sensation of intense coldness came; it was as though some icily cold creature fanned me with its wings! I cannot describe it, but it was numbing; I think I must have felt as those poor travellers do who succumb to the temptation to sleep in the snow."

Cairn surveyed her anxiously, for in its essentials this might be a symptom of a dreadful ailment.

"I aroused myself, however," she continued, "but experienced an unaccountable dread of entering my uncle's room. I could hear him muttering strangely, and—I forced myself to enter! I saw—oh, how can I tell you! You will think me mad!"

She raised her hands to her face; she was trembling. Robert Cairn took them in his own, forcing her to look up.

"Tell me," he said quietly.
