"Well, Hilda, the whole affair has been very simple, and there was not the least occasion for being anxious. I simply wanted to keep it quiet because I felt that you would raise all sorts of objections to the plan. We had, as you know, thought over a great many methods by which we might overhear a conversation between John Simcoe and the man on Pentonville Hill. But it seemed next to be impossible that it could be managed there. Suddenly the idea came into my brain that, as a servant at Simcoe's lodgings in Jermyn Street, I might have an excellent chance."
Hilda gave an exclamation of horror.
"My dear Netta, you never can really have thought of carrying this out?"
"I not only thought of it, but did it. With a little management the girl there was got hold of, and as it fortunately happened that she did not like London and wanted to take a country situation, there was very little difficulty, and she agreed to introduce me as a friend who was willing to take her place. Of course, it took a few days to make all the arrangements and to get suitable clothes for the place, and these I sent by parcel delivery, and on the morning of the day that the girl was to leave presented myself at the house. The man and his wife were good enough to approve of my appearance. They had, it seemed, three sets of lodgers, one on each floor; the man himself waited upon them, and my work was to do their rooms and keep the house tidy generally."
Again Hilda gave a gasp.
"There was nothing much in that," Netta went on, without heeding her. "I used to do most of the house work when we were in Germany, and I think that I gave every satisfaction. Of course the chief difficulty was about my deafness. I was obliged to explain to them that I was very hard of hearing unless I was directly spoken to. Mr. Johnstone always answered the bells himself when he was at home. Of course, when he was out it was my duty to do so. When I was downstairs it was simple enough, for I only had to go to the door of the room of which I saw the bell in motion. At first they seemed to think that the difficulty was insuperable; but I believe that in other respects I suited them so well that they decided to make the best of it, and when her husband was out and I was upstairs Mrs. Johnstone took to answering the door bells, or if a lodger rang, which was not very often, for her husband seldom went out unless they were all three away, she would come upstairs and tell me. Johnstone himself said to me one day that I was the best girl he had ever had, and that instead of having to go most carefully over the sitting rooms before the gentlemen came in for breakfast, he found that everything was so perfectly dusted and tidied up that there was really nothing for him to do.
"But oh, Hilda, I never had the slightest idea before how untidy men are! The way they spill their tobacco ash all over the room, and put the ends of their cigars upon mantelpieces, tables, and everywhere else, you would hardly believe it. The ground floor and the second floor were the worst, for they very often had men in of an evening, and the state of the rooms in the morning was something awful. Our man was on the first floor, and did not give anything like so much trouble, for he almost always went out in the evening and never had more than one or two friends in with him. One of these friends was the man we saw with him in the Row, and who, we had no doubt, was an accomplice of his. He came oftener than anyone else, very often coming in to fetch him. As he was always in evening dress I suppose they went to some club or to the theater together. I am bound to say that his appearance is distinctly that of a gentleman.
"I had taken with me two or three things that I foresaw I should want. Among them was an auger, and some corks of a size that would exactly fit the hole that it would make. Simcoe's bedroom communicated with the sitting room, and he always used this door in going from one room to the other; and it was evident that it was only through that that I could get a view of what was going on. I did not see how I could possibly make a hole through the door itself. It was on one side, next to that where the fireplace was, and there was a window directly opposite, and of course a hole would have been noticed immediately. The only place that I could see to make it was through the door frame. Its position was a matter of much calculation, I can assure you. The auger was half an inch bore. I dared not get it larger, and it would have been hopeless to try and see anything with a smaller one, especially as the hole would have to be four or five inches long. As I sometimes went into the room when they were together, either with hot water or grilled bones, or something of that sort, I was able to notice exactly where the chairs were generally placed. Simcoe sat with his back to the bedroom door, and the other man on the other side of the hearthrug, facing him. I, therefore, decided to make the hole on the side nearest to the wall, so that I could see the other man past Simcoe. Of course I wanted the hole to be as low as possible, as it would not be so likely to be noticed as it would were it higher up. I chose a point, therefore, that would come level with my eye when I was kneeling down.
"At about four o'clock in the afternoon they always went out, and from then till six Johnstone also took his airing, and I went upstairs to turn down the beds and tidy up generally. It was very seldom that any of them dined at home; I, therefore, had that two hours to myself. I got the line the hole should go by leaving the door open, fastening a stick to the back of a chair till it was, as nearly as I could judge, the height of the man's face, tying a piece of string to it and bringing it tight to the point where I settled the hole should start, and then marking the line the string made across the frame. Then there was a good deal more calculation as to the side-slant; but ten days ago I boldly set to work and bored the hole. Everything was perfectly right; I could see the head of the stick, and the circle was large enough for me to get all the man's face in view. Of course I had put a duster on the ground to prevent any chips falling onto the carpet.
"I was a little nervous when I set to work to drill that hole; it was the only time that I felt nervous at all. I had beforehand drilled several holes in the shelves of cupboards, so as to accustom myself to use the auger, and it did not take me many minutes before it came through on the other side. The corks were of two sizes; one fitted tightly into the hole, the other could be drawn in or out with very little difficulty. I had gone out one day and bought some tubes of paint of the colors that I thought would match the graining of the door frame. I also bought a corkscrew that was about an inch and a half shorter than the depth of the hole. It was meant to be used by a cross-piece that went through a hole at the top. I had got this cross-piece out with some trouble, and tied a short loop of string through the hole it had gone through. I put the corkscrew into one of the smaller corks and pushed it through until it was level with the frame on the sitting-room side, and found that by aid of the loop of string I could draw it out easily. Then I put one of the larger corks in at the bedroom side of the hole and pushed it in until it was level with that side. Then I painted the ends of the corks to resemble the graining, and when it was done they could hardly be noticed a couple of feet away.
