Yes—Checkley was looking at that window. No doubt of that at all. He was not able to disguise his astonishment: he no longer pretended to hide himself. For he saw, sitting in the window, the young lady whom he believed to be an accomplice in the crime; and standing over her, with an expression of fatherly affection, was none other than Mr. Dering himself.

Yes— Mr. Dering. Most wonderful! What did it mean? Had Mr. Dering resolved to clear up the mystery of Edmund Gray? Had he penetrated the Chambers and found there—not Edmund Gray—but Elsie Arundel?

'My friend,' said the Policeman, standing before him so that the view of the window was intercepted, 'you seem interested over the way.'

'I am. I am. Oh! yes. Much interested.'

'Well—don't you think you've looked at that old gentleman long enough? Perhaps he wouldn't like so much looking at. There's a young lady, too. It isn't manners to be staring at a young lady like a stuck pig.'

'No—no, Policeman— I've seen enough—thank you.'

'And, still talking in a friendly way, do you think Mr. Edmund Gray over there would like it if he knew there was a detective or a spy watching every evening on the other side of the Square? What's the little game, guv'nor? Anything in our line? Not with that most respectable old gentleman, I do hope—though sometimes—— Well—what is it? Because we can't have you goin' on as you have a been goin' on, you know.'

'Policeman'—Checkley pulled him aside and pointed to the little group at the window—'you see that old gentleman there—do you know him?'

'Certainly. Known him ever since I came to the Inn—two years ago. The people of the Inn have known him for ten years, I believe. That's Mr. Edmund Gray. He's not one of the regular residents, and he hasn't got an office. Comes here now and then when he fancies the place—Mr. Edmund Gray, that is. I wish all the gentlemen in the Inn were half as liberal as he is.'

'Oh! it's impossible! Say it again, Policeman. Perhaps I'm a little deaf—I'm very old, you know—a little deaf perhaps. Say it again.'
