‘Oh, I don’t know, Dad,’ she replied sweetly. ‘I had got interested in it, and I thought I would see it out myself. Well, as I was saying, Mr. Babylon,’ she continued, addressing her remarks to Felix, with a dazzling smile, ‘that noise went on for quite a long time. At last it stopped, and the figure reappeared from under the wall, crossed the yard, climbed up the opposite wall by some means or other, and so over the railings into Salisbury Lane. I felt rather relieved then, because I knew he hadn’t actually broken into the hotel. He walked down Salisbury Lane very slowly. A policeman was just coming up. “Goodnight, officer,” I heard him say to the policeman, and he asked him for a match. The policeman supplied the match, and the other man lighted a cigarette, and proceeded further down the lane. By cricking your neck from my window, Mr Babylon, you can get a glimpse of the Embankment and the river. I saw the man cross the Embankment, and lean over the river wall, where he seemed to be talking to some one. He then walked along the Embankment to Westminster and that was the last I saw of him. I waited a minute or two for him to come back, but he didn’t come back, and so I thought it was about time I began to make inquiries into the affair. I went downstairs instantly, and out of the hotel, through the quadrangle, into Salisbury Lane, and I looked over those railings. There was a ladder on the other side, by which it was perfectly easy--once you had got over the railings--to climb down into the yard. I was horribly afraid lest someone might walk up Salisbury Lane and catch me in the act of negotiating those railings, but no one did, and I surmounted them, with no worse damage than a torn skirt. I crossed the yard on tiptoe, and I found that in the wall, close to the ground and almost exactly under my window, there was an iron grating, about one foot by fourteen inches. I suspected, as there was no other ironwork near, that the mysterious visitor must have been sawing at this grating for private purposes of his own. I gave it a good shake, and I was not at all surprised that a good part of it came off in my hand, leaving just enough room for a person to creep through. I decided that I would creep through, and now wish I hadn’t. I don’t know, Mr Babylon, whether you have ever tried to creep through a small hole with a skirt on. Have you?’ ‘I have not had that pleasure,’ said little Felix, bowing again, and absently taking up a bottle which lay to his hand.
