Dyson made his way slowly along, mingling with the crowd on the cobble-stones, listening to the queer babel of French and German, and Italian and English, glancing now and again at the shop windows with their levelled batteries of bottles, and had almost gained the end of the street, when his attention was arrested by a small shop at the corner, a vivid contrast to its neighbours. It was the typical shop of the poor quarter; a shop entirely English. Here were vended tobacco and sweets, cheap pipes of clay and cherrywood; penny exercise books and penholders jostled for precedence with comic songs, and story papers with appalling cuts showed that romance claimed.its place beside the actualities of the evening paper, the bills of which fluttered at the doorway.

Dyson glanced up at the name above the door, and stood by the kennel trembling, for a sharp pang, the pang of one who has made a discovery, had for a moment left him incapable of motion.

The name over the shop was Travers. Dyson looked up again, this time at the corner of the wall above the lamppost, and read in white letters on a blue ground the words “Handel Street, W. C.”

and the legend was repeated in fainter letters just below. He gave a little sigh of satisfaction, and without more ado walked boldly into the shop, and stared full in the face of the fat man who was sitting behind the counter. The fellow rose to his feet, and returned the stare a little curiously, and then began in stereotyped phrase— “What can I do for you, sir?”

Dyson enjoyed the situation and a dawning perplexity on the man’s face. He propped his stick carefully against the counter and leaning over it, said slowly and impressively— “Once around the grass, and twice around the lass, and thrice around the maple-tree.”

Dyson had calculated on his words producing an effect, and he was not disappointed. The vendor of the miscellanies gasped, open-mouthed like a fish, and steadied himself against the counter. When he spoke, after a short interval, it was in a hoarse mutter, tremulous and unsteady.

“Would you mind saying that again, sir? I didn’t quite catch it.”

“My good man, I shall most certainly do nothing of the kind. You heard what I said perfectly well. You have got a clock in your shop, I see; an admirable timekeeper, I have no doubt. Well, I give you a minute by your own clock.”

The man looked about him in a perplexed indecision, and Dyson felt that it was time to be bold.

“Look here, Travers, the time is nearly up. You have heard of Q, I think. Remember, I hold your life in my hands. Now!”

Dyson was shocked at the result of his own audacity. The man shrank and shrivelled in terror, the sweat poured down a face of ashy white, and he held up his hands before him.

“Mr. Davies, Mr. Davies, don’t say that—don’t for Heaven’s sake. I didn’t know you at first, I didn’t indeed. Good God! Mr. Davies, you wouldn’t ruin me? I’ll get it in a moment.”

“You had better not lose any more time.”

The man slunk piteously out of his own shop, and went into a back parlour. Dyson heard his trembling fingers fumbling with a bunch of keys, and the creak of an opening box. He came back presently with a small package neatly tied up in brown paper in his hands, and still, full of terror, handed it to Dyson.

“I’m glad to be rid of it,” he said. “I’ll take no more jobs of this sort.”

Dyson took the parcel and his stick, and walked out of the shop with a nod, turning round as he passed the door. Travers had sunk into his seat, his face still white with terror, with one hand over his eyes, and Dyson speculated a good deal as he walked rapidly away as to what queer chords those could be on which he had played so roughly. He hailed the first hansom he could see and drove home, and when he had lit his hanging lamp, and laid his parcel on the table, he paused for a moment, wondering on what strange thing the lamplight would soon shine. He locked his door, and cut the strings, and unfolded the paper layer after layer, and came at last to a small wooden box, simply but solidly made. There was no lock, and Dyson had simply to raise the lid, and as he did so he drew a long breath and started back. The lamp seemed to glimmer feebly like a single candle, but the whole room blazed with light—and not with light alone, but with a thousand colours, with all the glories of some painted window; and upon the walls of his room and on the familiar furniture, the glow flamed back and seemed to flow again to its source,.the little wooden box. For there upon a bed of soft wool lay the most splendid jewel, a jewel such as Dyson had never dreamed of, and within it shone the blue of far skies, and the green of the sea by the shore, and the red of the ruby, and deep violet rays, and in the middle of all it seemed aflame as if a fountain of fire rose up, and fell, and rose again with sparks like stars for drops.

Dyson gave a long deep sigh, and dropped into his chair, and put his hands over his eyes to think.

The jewel was like an opal, but from a long experience of the shop windows he knew there was no such thing as an opal one quarter or one eighth of its size.
