Publio shook his head mutely, his tongue frozen to his palate. He could not speak.

One of the Khitans caught up a silken cover from a couch and threw it over the corpse. Then they melted behind the tapestry, but before the tallest man disappeared, he murmured: 'Talk to this man who comes, and send him away quickly. If you betray us, neither he nor you will live to reach that door. Make no sign to show him you are not alone.' And lifting his staff suggestively, the yellow man faded behind the hangings.

Publio shuddered and choked down a desire to retch. It might have been a trick of the light, but it seemed to him that occasionally those staffs moved slightly of their own accord, as if possessed of an unspeakable life of their own.

He pulled himself together with a mighty effort, and presented a composed aspect to the ragged ruffian who burst into the chamber.

'We have done as you wished, my lord,' this man exclaimed. 'The barbarian lies dead on the sands at the water's edge.'

Publio felt a movement in the arras behind him, and almost burst from fright. The man swept heedlessly on.

'Your secretary, Tiberio, is dead. The barbarian slew him, and four of my companions. We bore their bodies to the rendezvous. There was nothing of value on the barbarian except a few silver coins. Are there any further orders?'

'None!' gasped Publio, white about the lips. 'Go!'

The desperado bowed and hurried out, with a vague feeling that Publio was both a man of weak stomach and few words.

The four Khitans came from behind the arras.
