"Oh, no; an adjoining room would be an impossibility. Our building is an end one, standing on the corner of a short passage which leads to nothing but a narrow alley running along parallel with the back of our premises, and the glass-room covers nearly the entire roof of it. As a matter of fact, Mr. Cleek, although we call it that at the works, the term Glass Room is a misnomer. In reality, it's nothing more nor less than a good sized 'lean-to' greenhouse that the dad bought and had taken up there in sections, and its rear elevation rests against the side wall of a still higher building than ours, next door--the premises of Storminger the carriage builder, to be exact. But look here: perhaps I can make the situation clearer by a rough sketch. Got a lead pencil and a bit of paper, anybody? Oh, thanks very much, dear. One can always rely upon _you_. Now, look here, Mr. Cleek--this is the way of it. You mustn't mind if it's a crude thing, because, you know, I'm a rotten bad draughtsman and can't draw for nuts. But all the same, this will do at a pinch." Here he leaned over the table in the centre of the room and, taking the pencil and the blank back of the letter which Miss Larue had supplied, made a crude outline sketch thus: [Illustration of a group of houses] "There you are," he said suddenly, laying the crude drawing on the table before Cleek, and with him bending over it. "You are supposed to be looking at the houses from the main thoroughfare, don't you know, and, therefore, at the front of them. This tall building on the left marked 1 is Storminger's; the low one, number 2, adjoining, is ours; and that cagelike-looking thing, 3, on the top of it, is the glass-room. Now, along the front of it here, where I have put the long line with an X on the end, there runs a wooden partition with a door leading into the room itself, so that it's impossible for anybody on the opposite side of the main thoroughfare to see into the place at all. But that is not the case with regard to people living on the opposite side of the short passage (this is here, that I've marked 4), because there's nothing to obstruct the view but some rubbishy old lace curtains which Loti, in his endeavour to make the place what he calls homelike, would insist upon hanging, and _they_ are so blessed thin that anybody can look right through them and see all over the place. Of course, though, there are blinds, which he can pull down on the inside if the sun gets too strong; and when they are down, nobody can see into the glass-room at all. Pardon? Oh, we had it constructed of glass, Mr. Narkom, because of the necessity for having all the light obtainable in doing the minute work on some of the fine tableaux we produce for execution purposes. We are doing one now--The Relief of Lucknow--for the big exhibition that's to be given next month at Olympia and----The place marked 6 at the back of our building? Oh, that's the narrow alley of which I spoke. We've a back door
