"It must be a good window," said the young man.
"It is a magical window," said the old one.
"I have only ten shillings on me, but I have fifteen-and-six at home."
The old man thought for a while.
"Then twenty-five-and-sixpence is the price of the window," he said.
It was only when the bargain was completed and the ten shillings paid and the strange old man was coming for his fifteen-and-six and to fit the magical window into his only room that it occurred to Mr. Sladden's mind that he did not want a window. And then they were at the door of the house in which he rented a room, and it seemed too late to explain.
The stranger demanded privacy when he fitted up the window, so Mr. Sladden remained outside the door at the top of a little flight of creaky stairs. He heard no sound of hammering.
And presently the strange old man came out with his faded yellow robe and his great beard, and his eyes on far-off places. "It is finished," he said, and he and the young man parted. And whether he remained a spot of colour and an anachronism in London, or whether he ever came again to Baghdad, and what dark hands kept on the circulation of his twenty-five-and-six, Mr. Sladden never knew.
Mr. Sladden entered the bare-boarded room in which he slept and spent all his indoor hours between closing-time and the hour at which Messrs. Mergin and Chater commenced. To the Penates of so dingy a room his neat frock-coat must have been a continual wonder. Mr. Sladden took it off and folded it carefully; and there was the old man's window rather high up in the wall. There had been no window in that wall hitherto, nor any ornament at all but a small cupboard, so when Mr. Sladden had put his frock-coat safely away he glanced through his new window. It was where his cupboard had been in which he kept his tea-things: they were all standing on the table now. When Mr. Sladden glanced through his new window it was late in a summer's evening; the butterflies some while ago would have closed their wings, though the bat would scarcely yet be drifting abroad—but this was in London: the shops were shut and street-lamps not yet lighted.
Mr. Sladden rubbed his eyes, then rubbed the window, and still he saw a sky of blazing blue, and far, far down beneath him, so that no sound came up from it or smoke of chimneys, a mediaeval city set with towers; brown roofs and cobbled streets, and then white walls and buttresses, and beyond them bright green fields and tiny streams. On the towers archers lolled, and along the walls were pikemen, and now and then a wagon went down some old-world street and lumbered through the gateway and out to the country, and now and then a wagon drew up to the city from the mist that was rolling with evening over the fields. Sometimes folks put their heads out of lattice windows, sometimes some idle troubadour seemed to sing, and nobody hurried or troubled about anything. Airy and dizzy though the distance was, for Mr. Sladden seemed higher above the city than any cathedral gargoyle, yet one clear detail he obtained as a clue: the banners floating from every tower over the idle archers had little golden dragons all over a pure white field.
