I repeated Kennedy's message.
"Well, that's too bad," replied Lockwood. "I've just seen Mr. Whitney, and he tells me that Kennedy and you are pretty friendly with Norton, Of course, I knew that. I saw you at the Mendozas' together the first time. I'd like to have a talk with him about that man. I suppose he has told you all his side of the story of his relations with Whitney."
I am, if anything, a good listener, and so I said nothing, not even that he had better tell it to Kennedy in the morning, for it was such a novelty to have any of these people talk voluntarily that I really didn't much care whether I believed what they said or not.
"I used to know him down in Lima, you know," went on Lockwood. "What I want to say has to do with that dagger he says was stolen. I want to tell what I know of how he got it. There was an Indian mixed up in it who committed suicide—well, you tell Kennedy I'll see him in the morning."
Lockwood rang off, and I repeated what he had told me, as Kennedy continued to adjust the apparatus.
"Say," I exclaimed, as I finished. "That was a harry's of a commission you gave Norton just now, watching the de Moches. Why, they'd eat him alive if they got a chance, and I don't know that all's like a Sunday school on his part. Lockwood doesn't seem to think so."
Kennedy smiled quietly. "That was why I asked him to do it," he returned. "I thought that he wouldn't let much escape him. They all seem so down on him, he'll have to watch out. It will keep him busy, too, and that means a chance for us to work."
He had finished setting up the machine, and now went over to another drawer, from which he took the envelope of stubs which we had taken down at Whitney's office first. Then from the pocket of his street coat he drew both the second envelope of ashes and stubs, the whole cigarette from Lockwood's case, and the stubs which both of us had saved from the cigarettes that had once belonged to Mendoza.
Carefully he separated and labelled them all, so that there would be no chance for them to get mixed up. Then he picked up one of the stubs and lighted it. The smoke curled up in wreaths between a powerful light and the peculiar instrument, while Craig peered through a lens, manipulating the thing with exhaustless patience and skill. I watched him curiously, but said nothing, for he was studying something carefully, and I did not want to interrupt his train of thought.
Finally he beckoned me over. "Can you make anything out of that?" he asked.
