's?"

"I have. And what is more, I can identify her," I replied. "Her name is
Armida, and she was wife of the murdered man Olinto Santini."

"Then both husband and wife were killed?"

"Without a doubt--a double tragedy."

"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."

"Certainly. Let us go," he exclaimed, rising at once and ringing his
bell.

"Get three good lanterns and some matches, and put them in this
gentleman's trap outside," he said to the constable who answered his
summons. "And tell Gilbert Campbell that I want him to go with me up to
Rannoch Wood."

"Yes, sir," answered the man; and the door again closed.

"It's a pity--a thousand pities, Mr. Gregg, that you didn't stop those
two men who buried the body."

"They were already across the stream, and disappearing into the thicket
before I mounted the rock," I explained. "Besides, at the moment I had
no suspicion of what they'd been doing. I believed them to be stragglers
from a neighboring shooting-party who had lost their way."

"Ah, most unfortunate!" he said. "I hope they don't escape us. If
they're foreigners, they are not likely to get away. But if they're
English or Scots, then I fear there's but little chance of us coming up
with th
