Nick thought of these things as he rode down there in the cars, and he prepared himself for an interesting time, chasing bogus ghosts through secret doors and panels.
But a surprise awaited him on his arrival. Colonel Richmond met him at the door, and, by Nick's request, took him at once to the room from which the articles had been stolen.
It was a modern room in a new part of the house.
Nick was entirely unprepared for this. He did not know that the colonel had built any additions to the old mansion.
Colonel Richmond spoke of this remarkable feature of the case at once.
“If this thing had happened in the old part of the house,” he said, “I shouldn't have thought that it was anything but an ordinary robbery.
“Every room there can be entered in a secret manner, and no doubt there are plenty of panels and passages which even I do not know.
“But there's nothing of the kind here. This wing was built under my eye, and from my own design. I saw the beams laid and the floors nailed down.
“There is absolutely no way to enter the room in which we now stand except by the two doors and the window.
“My nephew has told you about the robberies. You know that the doors and the windows were practically guarded all the time.
“I don't believe that any mortal being could have got in here and got out again without being seen.
“As for myself, I understand the case perfectly. My belief will seem strange to you, because you do not see with the eye of the spirit. Everything has to be done by human hands, according to your matter-of-fact notion.
“I know better; and I tell you that these jewels were taken by the spirit of my deceased aunt, and that she did it to show me that my daughter was wrongfully in possession of them.”
When a healthy, hearty old man, who seems to be as sane as anybody else in the world, stands up and talks such nonsense as this, what can one say to him?
It is useless to tell him that he is wrong about the whole matter. It is folly to attempt to reason with him.
The only way to do is to show him a perfectly natural explanation of the mystery, and simply make him see it.
That was the task which Nick had before him, and it must be owned that, at the first glance, he did not see how he was going to accomplish it.
He examined the room and satisfied himself that it had no secret entrances.
Such being the case, Nick was unable to form a theory of the robbery which would fit the facts as they had been stated to him.
After looking at the rooms, he went with Colonel Richmond to the parlor, on the ground floor, and there proceeded to question him about the mysterious occurrences.
“There have been three robberies in all,” said the colonel, “and they have been exactly alike.
“In every case my daughter has left some articles of jewelry on the dressing-table in her bed-room, and one of them has vanished. Never more than one at a time.
“Twice it happened while she was in the adjoining room. The bed-room door which opens into the hall was locked on these occasions.
“The third time she was in the hall, talking with my nephew. He was standing in the upper hall, leaning over the banister rail. They were discussing a plan for a drive out into the country. Quite a party was to go.
“Horace had just received word from a gentleman whom they had invited that he would be unable to go. He had read the note in his room, and he called downstairs to my daughter to tell her about it.
“That was how they happened to be standing in the hall. Presently she went back into her room, and almost immediately noticed that a small locket set with diamonds had been taken.
“She screamed, and Horace and I came running to her room. We searched it thoroughly.
“There was nobody there. The door between the bedroom and the sitting-room was open, but the other door of the sitting-room, which opens into the old portion of the house, was locked and bolted on the inside.
“Now, I submit to you, Mr. Carter, whether in that case any other way of entrance or exit was possible except by the windows.”
“I'm bound to admit,” responded Nick, “that if the doors were in the condition you describe, no person could have entered or left those rooms except by the windows.”
“Well, it had been raining hard, and the ground was soft. We looked carefully under all the windows.
“There was no sign of a footprint, and nobody could have walked there without making tracks. Oh, it is clear enough! Why do we waste your time in a search for invisible spirits of the dead?”
He rambled on in this way for several minutes, and Nick did not try to stop him.
The colonel was at last interrupted, however, by the entrance of his daughter.
Mrs. Pond had been out driving. She learned, on her return, that a stranger had come to the house, and she hurried into the parlor, suspecting who was there.
“I am delighted to see you, Mr. Carter,” she exclaimed. “You will clear up this abominable mystery and relieve my father's mind from these delusions.”
