“At last I took this box from a drawer of my dressing-table and put the jewels into it.

“Then I called to the servant who was in the dining-room, and asked her to see that the carriage was got ready, for though it is a long drive, I had resolved to make it, because I felt safer in that way.”

“Did you go out of your room to call the girl?”

“Only into the hall.”

“Who could have got into your room while you were out?”

“Nobody.”

“Where was your daughter?”

“In her own room.”

“How do you know?”

“I called to her after I had dressed, and she answered me.  I told her that I was going to drive over here, and she was very much surprised.  I did not tell her why.”

“Did you meet anybody on the way over who spoke to you or came to the side of the carriage?”

“Nobody.”

“That is all I wish to ask.”

In fact, Nick had no more questions.  He was really at a loss for an explanation of this strange occurrence.

If the pin had been taken from the room, by a person concealed in the house, it might have been possible that that person had escaped from the grounds unseen, and had given it to Mrs. Stevens.

There was hardly time for such a trick to have been done, but in so strange a case every possibility was to be considered.

If such a thing had been done, it must have been very near to the house.

The thief must have known when Mrs. Stevens was coming, or she must have waited for him just outside the colonel’s grounds.

There was a place where the road was heavily fringed with trees, not more than a hundred yards from the colonel’s gate.

The trick must have been done there, if at all.

Nick resolved to settle this small point, if possible, immediately.

It was of no use to ask the man who had driven Mrs. Stevens’ horse.  Of course, he would lie, if there was any need of it.

So Nick excused himself from the group on the pretext that he was going to search Mrs. Pond’s rooms again.

He remembered that just after Mrs. Stevens had arrived, a wagon belonging to the colonel had driven into the grounds.  He quietly looked up the two servants who had been in this wagon.  They told him that they remembered seeing Mrs. Stevens drive up.

She had passed them on the road.  They had had her carriage in sight for a mile before it turned into Colonel Richmond’s grounds.

Her horse had been driven at a good pace.  It had not stopped.  Nobody had approached the carriage.

Nick was convinced that the men were telling the truth.

Then how had Mrs. Stevens obtained that pin?

Her possession of the other articles might be explained, but the pin was a “stickler.”
