“What!” gasped Mrs. Maloney, “a phenomenon?—you mean that you know what it is?”

“I am quite certain I know what it is,” he replied very low, for we heard the footsteps of Sangree approaching, “though I am not so certain yet as to the best means of dealing with it. But in any case it is not wise to leave precipitately——”

“Oh, Timothy, does he think it’s a devil——?” cried the Bo’sun’s Mate in a voice that even the Canadian must have heard.

“In my opinion,” continued John Silence, looking across at me and the clergyman, “it is a case of modern lycanthropy with other complications that may——” He left the sentence unfinished, for Mrs. Maloney got up with a jump and fled to her tent fearful she might hear a worse thing, and at that moment Sangree turned the corner of the stockade and came into view.

“There are footmarks all round the mouth of my tent,” he said with excitement. “The animal has been here again in the night. Dr. Silence, you really must come and see them for yourself. They’re as plain on the moss as tracks in snow.”

But later in the day, while Sangree went off in the canoe to fish the pools near the larger islands, and Joan still lay, bandaged and resting, in her tent, Dr. Silence called me and the tutor and proposed a walk to the granite slabs at the far end. Mrs. Maloney sat on a stump near her daughter, and busied herself energetically with alternate nursing and painting.

“We’ll leave you in charge,” the doctor said with a smile that was meant to be encouraging, “and when you want us for lunch, or anything, the megaphone will always bring us back in time.”

For, though the very air was charged with strange emotions, every one talked quietly and naturally as with a definite desire to counteract unnecessary excitement.

“I’ll keep watch,” said the plucky Bo’sun’s Mate, “and meanwhile I find comfort in my work.” She was busy with the sketch she had begun on the day after our arrival. “For even a tree,” she added proudly, pointing to her little easel, “is a symbol of the divine, and the thought makes me feel safer.” We glanced for a moment at a daub which was more like the symptom of a disease than a symbol of the divine—and then took the path round the lagoon.

At the far end we made a little fire and lay round it in the shadow of a big boulder. Maloney stopped his humming suddenly and turned to his companion.
