Dyson was shocked at the result of his own audacity. The man shrunk 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 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. He looked at the stone again, with a feeling that was almost awe, and placed it gently on the table under the lamp, and watched the wonderful flame that shone and sparkled in its centre, and then turned to the box, curious to know whether it might contain other marvels. He lifted the bed of wool on which the opal had reclined, and saw beneath, no more jewels, but a little old pocket-book, worn and shabby with use. Dyson opened it at the first leaf, and dropped the book again appalled. He had read the name of the owner, neatly written in blue ink:—

STEVEN BLACK, M.D.,
