A scratch indeed!

In an instant his subtle mind followed the trail unerringly. The trick of a false diamond which he and Abulfazl had urged upon Akbar had been played here. But how? Who was the culprit? His knowledge of humanity, of the world and its ways, instantly exculpated the Englishman from implication in the theft. But had he been careless? That was a point for inquiry; but now, this instant moment, what was to be done? what had best be done?

"Sit silent on yonder stool and work out thy problem, fool!" he said in a whisper to William Leedes, who stood gaping, ready to burst out into speech when it came back to him, "and leave me to work out mine. This is no diamond. 'Tis a false gem made, I swear by Pooru; but to whose order? And for what purpose?"

He paced the little workshop, every fibre of his keen wit vibrating to the tense pressure of his thought. Then he laid his hand suddenly on the amazed jeweller's shoulder.

"When didst thou leave it--only for a moment? Speak truth."

But William Leedes brain had already begun to work slowly.

"Diswunt!" he said mechanically, "he showed me."

The next minute they stood looking round the painter's empty studio. Through the corbeilled balcony they could see the miracle of dawn being enacted, but in the wide, cool, airy room was nothing.

"What did he show thee?" asked Birbal menacingly. For answer William Leedes threw back the door. It fell into its place with a clang of chain upon staple, leaving disclosed no hunting scene; that had been fiercely rubbed off, leaving gray clouds upon the whitewashed wood; but on this indefinite background, limned in with large lines and splashes of a curious scarlet was the figure of a woman. A woman standing, her feet moving in a rhythmic dance, her scarf floating in serpentine curves.

"Siyah Yamin!" cried Birbal under his breath, and stooped to read a legend, dashed in roughly--with the brush, apparently, that still stood half immersed in a bowl, where lingered dregs of the same curious ghastly crimson scarlet pigment with which the portrait was limned.
