“Is the Camp asleep?” the doctor asked presently, whispering.
“Sangree is,” replied the clergyman, in a voice equally low. “I can’t answer for the women; I think they’re sitting up.”
“That’s for the best.” And then he added: “I wish the fog would thin a bit and let the moon through; later—we may want it.”
“It is lifting now, I think,” Maloney whispered back. “It’s over the tops of the trees already.”
I cannot say what it was in this commonplace exchange of remarks that thrilled. Probably Maloney’s swift acquiescence in the doctor’s mood had something to do with it; for his quick obedience certainly impressed me a good deal. But, even without that slight evidence, it was clear that each recognised the gravity of the occasion, and understood that sleep was impossible and sentry duty was the order of the night.
“Report to me,” repeated John Silence once again, “the least sound, and do nothing precipitately.”
He shifted across to the mouth of the tent and raised the flap, fastening it against the pole so that he could see out. Maloney stopped humming and began to force the breath through his teeth with a kind of faint hissing, treating us to a medley of church hymns and popular songs of the day.
Then the tent trembled as though someone had touched it.
“That’s the wind rising,” whispered the clergyman, and pulled the flap open as far as it would go. A waft of cold damp air entered and made us shiver, and with it came a sound of the sea as the first wave washed its way softly along the shores.
“It’s got round to the north,” he added, and following his voice came a long-drawn whisper that rose from the whole island as the trees sent forth a sighing response. “The fog’ll move a bit now. I can make out a lane across the sea already.”
“Hush!” said Dr. Silence, for Maloney’s voice had risen above a whisper, and we settled down again to another long period of watching and waiting, broken only by the occasional rubbing of shoulders against the canvas as we shifted our positions, and the increasing noise of waves on the outer coastline of the island. And over all whirred the murmur of wind sweeping the tops of the trees like a great harp, and the faint tapping on the tent as drops fell from the branches with a sharp pinging sound.
We had sat for something over an hour in this way, and Maloney and I were finding it increasingly hard to keep awake, when suddenly Dr. Silence rose to his feet and peered out. The next minute he was gone.
Relieved of the dominating presence, the clergyman thrust his face close into mine. “I don’t much care for this waiting game,” he whispered, “but Silence wouldn’t hear of my sitting up with the others; he said it would prevent anything happening if I did.”
“He knows,” I answered shortly.
“No doubt in the world about that,” he whispered back; “it’s this ‘Double’ business, as he calls it, or else it’s obsession as the Bible describes it. But it’s bad, whichever it is, and I’ve got my Winchester outside ready cocked, and I brought this too.” He shoved a pocket Bible under my nose. At one time in his life it had been his inseparable companion.
“One’s useless and the other’s dangerous,” I replied under my breath, conscious of a keen desire to laugh, and leaving him to choose. “Safety lies in following our leader—”
“I’m not thinking of myself,” he interrupted sharply; “only, if anything happens to Joan tonight I’m going to shoot first—and pray afterwards!”
Maloney put the book back into his hip-pocket, and peered out of the doorway. “What is he up to now, in the devil’s name, I wonder!” he added; “going round Sangree’s tent and making gestures. How weird he looks disappearing in and out of the fog.”
“Just trust him and wait,” I said quickly, for the doctor was already on his way back. “Remember, he has the knowledge, and knows what he’s about. I’ve been with him through worse cases than this.”
Maloney moved back as Dr. Silence darkened the doorway and stooped to enter.
“His sleep is very deep,” he whispered, seating himself by the door again. “He’s in a cataleptic condition, and the Double may be released any minute now. But I’ve taken steps to imprison it in the tent, and it can’t get out till I permit it. Be on the watch for signs of movement.” Then he looked hard at Maloney. “But no violence, or shooting, remember, Mr. Maloney, unless you want a murder on your hands. Anything done to the Double acts by repercussion upon the physical body. You had better take out the cartridges at once.”
His voice was stern. The clergyman went out, and I heard him emptying the magazine of his rifle. When he returned he sat nearer the door than before, and from that moment until we left the tent he never once took his eyes from the figure of Dr. Silence, silhouetted there against sky and canvas.
And, meanwhile, the wind came steadily over the sea and opened the mist into lanes and clearings, driving it about like a living thing.
It must have been well after midnight when a low booming sound drew my attention; but at first the sense of hearing was so strained that it was impossible exactly to locate it, and I imagined it was the thunder of big guns far out at sea carried to us by the rising wind. Then Maloney, catching hold of my arm and leaning forward, somehow brought the true relation, and I realised the next second that it was only a few feet away.
“Sangree’s tent,” he exclaimed in a loud and startled whisper.
I craned my head round the corner, but at first the effect of the fog was so confusing that every patch of white driving about
