Yet his spring was an instant delayed and in that instant Ryder spoke again.

"Look, now at the wall behind you," he said quickly.

Yussuf looked. And as he turned his bullet head Ryder jumped close and brought his iron down upon it with a sickening force he thought scarcely short of murder.

To his amazement the black did not fall, but staggered only, and Ryder had need to send the knife spinning from his grasp and strike again before the eunuch's knees sagged and his huge bulk sank at Ryder's feet.

This time Ryder took no chance with a shammed unconsciousness. He snatched down bits of leather from the wall and bound the man's hands and feet in tight security and seeing that he was breathing, although heavily, he thrust a gagging handkerchief into his mouth.

Then he dragged the heavy body towards a pile of hay he saw in a vacant stall and concealed it effectively but not too smotheringly—although Yussuf, he felt, would be no grievous loss to society.

Vaguely in the back of his consciousness he had been aware of the excited plunge of the horse and then of a low, soothing murmur of speech, and now he turned to find Aimée holding the bridle and stroking the quivering creature with gentle, fearless hands.

"Is he dead?" she asked quietly of the eunuch.

"Stunned," said Ryder, meaning reassurement and was startled by the passion of her cry, "Oh, I could kill them all—all!"

"I will—if they try to stop us," he promised grimly, forgetful of that oath to Aziza.
