colonel introduced Nick by his right name.
“Here is an extraordinary thing, Mr. Carter,” he said. “We now have proof positive that this affair is not the work of mortal hands.”
“What is that?” asked Nick.
“The jewels have appeared!”
“Where?”
“In Mrs. Stevens' house. They have been mysteriously transported there without human aid.”
“I should be glad to have that proven,” said Nick.
“It shall be,” said the colonel. “Tell your story, Mrs. Stevens, if you please.”
“It is very simple,” she said. “This noon, when I returned to my room after lunch, I found upon my dressing-table certain pieces of jewelry which I recognized as having belonged to the late Miss Lavina Richmond.
“I knew them well. Nothing that I can imagine could have surprised me more than to find them there. I have no explanation to offer. I can't explain how it happened.”
Nick could explain it very easily, at least so far as the appearance of the jewels in that particular place was concerned. It looked like a natural development of the plot. But his face expressed no emotion as he asked:
“Who had access to that room?”
“Nobody,” replied Mrs. Stevens. “It was locked.”
“Is it customary for you to lock your bed-room door when you go to lunch?”
“No; it is quite unusual. But we have a new servant in the house, and, as I had considerable money in the room, I took that precaution.
“All the doors were locked. I had the key to one of them. The others were on the inside of the locks.
“When I went to lunch the jewels were not there. When I returned they were there. That is all that I know about it. Here they are.”
She drew from her pocket as she spoke a small cardboard box.
The woman was making heroic efforts to be calm, but it seemed as if she might either faint or go into hysterics at any moment.
Was she playing a game that was too hard for her?
That was the question for Nick to answer; and yet, when he looked at this gentle, refined woman, he hardly had the heart to suspect her of any dishonesty.
“I will show you the jewels,” she said, struggling to command her voice, “you can then see whether they are all here.”
Her trembling hands could hardly find the string which was tied about the box.
While she pulled at it she kept talking as if she must do it to relieve her overburdened mind. She described the articles of jewelry which were in the box.
“They are the very ones,” said the colonel.
As he uttered the words the string was loosened, and the cover fell off the box.
There was a sharp cry. It came from Mrs. Pond, who, with Horace, had approached during this scene.
“Why, there's one of my diamond pins!” she exclaimed. “How on earth did it come to be there?”
Well, if Mrs. Pond was surprised, she wasn't a bit more so than Nick Carter.
The pin referred to was the one which had been stolen from the cushion in Mrs. Pond's dressing-room not ten minutes before.
“Why, this is impossible,” cried Mrs. Pond. “I left that pin with the two others like it in my room.”
Without saying another word, she turned and ran into the house.
Almost immediately her voice was heard in the hall.
“It's gone!” she cried. “It's been taken out of my bedroom.”
She appeared at the door with a very white face.
But her excitement was nothing to that of Mrs. Stevens.
Nick dropped the role of detective and assumed that of doctor in less than a second.
When he had saved Mrs. Stevens from an attack of hysterics, he said:
“I was aware that that pin had been taken. It was done while I was in your room, Mrs. Pond. The circumstances were exactly the same as those attending the other robberies.”
“But I did not put it in the box,” exclaimed Mrs. Stevens. “It was not among the jewels which I found.”
She turned to Colonel Richmond. Her face was ghastly pale.
“I have scorned your belief,” she said; “but now I am convinced. No mortal being could have done this
