“Ah, Miss Wragge,” he repeated with increased gravity, “Miss Wragge—”

A knock at the door brought a servant with word that tea was ready, and the Colonel had sent to ask if we were coming down. The thread was broken. Dr. Silence moved to the door and signed to me to follow. But his manner told me that in any case no real answer would have been forthcoming to my question.

“And the place to dig in,” I asked, unable to restrain my curiosity, “will you find it by some process of divination or—?”

He paused at the door and looked back at me, and with that he left me to finish my dressing.

It was growing dark when the three of us silently made our way to the Twelve Acre Plantation; the sky was overcast, and a black wind came out of the east. Gloom hung about the old house and the air seemed full of sighings. We found the tools ready laid at the edge of the wood, and each shouldering his piece, we followed our leader at once in among the trees. He went straight forward for some twenty yards and then stopped. At his feet lay the blackened circle of one of the burned places. It was just discernible against the surrounding white grass.

“There are three of these,” he said, “and they all lie in a line with one another. Any one of them will tap the tunnel that connects the laundry—the former Museum—with the chamber where the mummy now lies buried.”

He at once cleared away the burnt grass and began to dig; we all began to dig. While I used the pick, the others shovelled vigorously. No one spoke. Colonel Wragge worked the hardest of the three. The soil was light and sandy, and there were only a few snake-like roots and occasional loose stones to delay us. The pick made short work of these. And meanwhile the darkness settled about us and the biting wind swept roaring through the trees overhead.

Then, quite suddenly, without a cry, Colonel Wragge disappeared up to his neck.

“The tunnel!” cried the doctor, helping to drag him out, red, breathless, and covered with sand and perspiration. “Now, let me lead the way.” And he slipped down nimbly into the hole, so that a moment later we heard his voice, muffled by sand and distance, rising up to us.

“Hubbard, you come next, and then Colonel Wragge—if he wishes,” we heard.
