"May I have a cigarette out of that case over there?" he asked, indicating a box of them on a table.
"Why--that is Mr. Lockwood"s," she replied. "He left it here the last time he was here and I forgot to send it to him. Wait a minute. Let me get you some of father"s."
She left the room. The moment the door closed Kennedy reached over and took one from the case. "I have some of Lockwood"s already, but another won"t matter, as long as I can get it," he said. "I thought it was her father"s. When she brings them, smoke one with me, and be careful to save the stub. I want it."
A moment later she entered with a metal box that must have held several hundred. Kennedy and I each took one and lighted it, then for several minutes chatted as an excuse for staying. As for myself, I was glad enough to leave a pretty large stub, for I did not like it. These cigarettes, like those Whitney had offered us, had a peculiar flavour which I had not acquired a liking for.
"You must let me know whether anything else develops from the meeting in the tea room," said Kennedy finally, rising. "I shall be at the laboratory some time, I think."

THE INTERFEROMETER
Norton was waiting for us at the laboratory when we returned, evidently having been there some time.
"I was on my way to my apartment," he began, "when I thought I"d drop in to see how things are progressing."
"Slowly," returned Kennedy, throwing off his street clothes and getting into his laboratory togs.
"Have you seen Whitney since I had the break with him?" asked Norton, a trifle anxiously.
I wondered whether Kennedy would tell Norton what to expect from Whitney. He did not, however.
"Yes," he replied, "just now we had an appointment with Senora de Moche and some others and ran into him at the hotel for a few moments."
"What did he say about me?" queried Norton.
"He hadn"t changed his mind," evaded Kennedy. "Have you heard anything from him?"
"Not a syllable. The break is final. Only I was wondering what he was telling people about me. He"ll tell them something--his side of the case."
"Well," considered Kennedy, as though racking his brain for some remark which he remembered, while Norton watched him eagerly, "I do recall that he was terribly sore about the loss of the dagger, and seemed to think that it was your fault."
"I thought so, I knew it," replied Norton bitterly. "I can see it coming. All the trustees will hear of my gross negligence in letting the Museum be robbed. I suppose I ought to sit up there all night. Oh, by the way, there"s another thing I wanted to ask you. Have you ever done anything with those shoe-prints you found in the dust of the mummy case?"
I glanced at Kennedy, wondering whether he felt that the time had come to reveal what he had discovered. He said nothing for a moment, but reached into a drawer and pulled out the papers, which I recognized.
"Here they are," he said, picking out the original impression which he had taken.
"Yes," repeated Norton, "but have you been able to do anything toward identifying them?"
"I found it rather hard to collect prints of the shoes of all of those I wished to compare. But I have them at last."
"And?" demanded Norton, leaning forward tensely.
"I find that there is one person whose shoe-prints are precisely the same as those we found in the Museum," went on Kennedy, tossing over the impression he had taken.
Norton scanned the two carefully. "I"m not a criminologist," he said excitedly, "but to my untrained eye it does seem as though you had here a replica of the first prints, all right." He laid them down and looked squarely at Kennedy. "Do you mind telling me whose feet made these prints?"
"Turn the second over. You will see the name written on it."
"Lockwood!" exclaimed Norton in a gasp as he read the name. "No--you don"t mean it."
"I mean nothing less," repeated Kennedy firmly. "I do not say what happened afterwards, but Lockwood was in the Museum, hiding in the mummy case, that night."
Norton"s mind was evidently working rapidly. "I wish I had your power of deduction, Kennedy," he said, at length. "I suppose you realize what this means?"
"What does it mean to you?" asked Kennedy, changing front.
Norton hesitated. "Well," he replied, "it means to me, I suppose, what it means to any one who stops to think. If Lockwood was there, he got the dagger. If he had the dagger--it was he who used it!"
The inference was so strong that Craig could not deny it. Whether it was his opinion or not was another matter.
"It fits in with other facts, too," continued Norton. "For instance, it was Lockwood who discovered the body of Mendoza."
"But the elevator boy took Lockwood up himself," objected Craig, more for the sake of promoting the discussion than to combat Norton.
"Yes--when he "discovered" the thing. But it must have been done long before. Who knows? He may have entered. The deed might have been done.
He may have left. No one saw him come or go. What then more likely to cover himself up than to return when he knew that his entrance would be known, and find the thing himself?"
Norton"s reasoning was clever and plausible. Yet Kennedy scarcely nodded his head, one way or the other.
"You were acquainted with Lockwood?" he asked finally. "I mean to say, of course, before this affair."
"Yes, I met him in Lima just as I was starting out on my expedition. He was preparing to come to New York."
"What did you think of him then?"
"Oh, he was all right, I suppose. He wasn"t the sort who would care much for an archaeologist. He cared more for a prospector going off into the hills than he did for me. And I--I admit that I am impossible.
Archaeology is my life."
Norton continued to study the prints. "I can hardly believe my eyes,"
he murmured; then he looked up suddenly. "Does Whitney know about this--or Lockwood?"
Kennedy shook his head negatively.
"Because," pursued Norton, "an added inference to that I spoke of would be that the reason why they are so sure that they will find the treasure is that they are not going on tradition, as they say, but on the fact itself."
"A fair conclusion," agreed Craig.
"I wish the break could have been postponed," continued Norton. "Then I might have been of some service in my relation to Whitney. It"s too late for me to be able to help you in that direction now, however."
"There is something you can do, though," said Craig.
"I shall be delighted," hastened Norton. "What is it?"
