“I’m glad of that at least,” said Van Bleit.

“There were other matters contained in the letter besides his recall which concern you,” Simmonds added. “He wishes to see you on the subject.”

“You may tell him from me,” Van Bleit answered rudely, “that his postal communications, as his movements, have not the slightest interest for me.”

He started to walk again. Simmonds, wholly unmoved, walked beside him.

“You speak without knowledge, Mr Van Bleit,” he said. “The instructions contained in this imperative and important letter concern you very particularly. Colonel Grey has a further proposal to lay before you, which you will be well advised to consider. Failing a satisfactory issue to these final negotiations, he is instructed to place the matter in the hands of the police and return to England.”

Van Bleit, his assurance notwithstanding, was taken aback. He had not foreseen this move, and was totally unprepared for it. It was merely bluff, he told himself, and really believed it was so; but at the back of the belief lurked the fear that his victim might have grown reckless, and, with the courage that is sometimes born of despair, be prepared to face the worst.

“Faugh!” he exclaimed impatiently. “That’s an old dodge.” But his voice had lost its confidence and resumed its natural bullying tones. “Go and tell your chief to do his worst, and be damned to him!”

“Go and tell him yourself,” returned Simmonds. “You could at least then hear what he has to say.”

“And how do I know you are not up to some treachery?” demanded Van Bleit, his suspicions at once on the alert.

“I suppose it is natural you should judge other men by your own standard,” Simmonds answered indifferently. “If you are afraid we may arrange a trap, why not go and see him to-night when he is unprepared for your visit?”
