"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.
