"But the two men who concealed the body! Will you describe them?"

I did so, and he wrote at my dictation, afterwards remarking—

"We must find them." And calling in one of his sub-inspectors, he gave him instructions for the immediate circulation of the description to all the police-stations in the county, saying the two men were wanted on a charge of willful murder.

When the official had gone out again and we were alone, Mackenzie turned to me and asked—

"What induced you to search the wood? Why did you suspect a second crime?"

His question nonplused me for the moment.

"Well, you see, I had identified the young man Olinto, and knowing him to be married and devoted to his wife, I suspected that she had accompanied him here. It was entirely a vague surmise. I wondered whether, if the poor fellow had fallen a victim to his enemies, she had not also been struck down."

His lips were pressed together in distinct dissatisfaction. I knew my explanation to be a very lame one, but at all hazards I could not import Muriel's name into the affair. I had given her my promise, and I intended to keep it.

"Then the body is still in the glen, where you left it?"

"Yes. If you wish, I will take you to the spot. I can drive you and your assistant up there."
