I remembered that I was alone with him in there, miles from everywhere. When standing, he towered high above me, a veritable giant, and I knew that, if he chose to attack me, he must overcome me with the greatest ease. At all costs I must pacify him.

“Perhaps now,” I said calmly, “you think there is more in my theory than at first appeared. Listen to me, Mr Whichelo,” I went on, forcing my courage, “from what I have said, and hinted, you probably guess that I know—well—something. It remains for you to decide whether we are to be friends—or not. Personally, I am willing to be friendly with you. Thorold and I are friends, and have been for years.

“You!” he gasped, surprised.

“Yes, but don’t interrupt me,” I said. “You and he brought the body to light and intended to smuggle it out of the house in a packing-case.”

I stopped. Then, with my eyes still set on his, I said—
