“And how did you discover that?” the other inquired sceptically. “Told you, I suppose?”

“Not much,” Van Bleit answered craftily. “But I keep a watch on the Colonel’s doings, and I know fairly accurately all the visitors he receives at the bungalow. It was the greatest surprise in the world to me when I tracked Grit Lawless there. I watched him unseen go in and out on three separate occasions. He has passed me so close that by stretching out a hand he could have touched me, and bade me good-night in response to my ‘Good-night, baas,’ taking me for the Kaffir I disguised myself to represent. He is very wide awake is Grit Lawless, but I’m wider awake still. I’ve followed him up to the stoep of the bungalow and heard him greet the old man, unconscious of a listener. He can’t kid me. The only thing that puzzles me is his absconding with that she-devil. It’s just possible that he has had a split with the Colonel. But that doesn’t make him any friend of ours, you understand. Grit is cunning enough to play the game off his own bat. I’m not for trusting any man. We’ll go, but we’ll need to be wide awake.”

Denzil looked at the speaker admiringly. He was cunning himself; it was due to his fertile brain that the letters had fallen into Van Bleit’s hands, otherwise he would never have participated in the profits; but his cunning was not equal to the Dutchman’s, nor his courage. He was a nervous little fellow, and would gladly have parted with the letters for the handsome sum offered by the other side. He was always keenly alive to the danger of his profession as blackmailer. It was only his fear of Van Bleit that kept him in subjection. And he was sorely afraid that Van Bleit would overreach himself and land them both some day into difficulties with the law.

“Why go,” he asked sensibly, “if you don’t trust the man?”

Van Bleit shrugged his huge shoulders.

“It suits me to go somewhere,” he answered. “And I’d like to test the fellow.”

“You’re more than a match for him,” Denzil remarked tentatively.

Van Bleit smiled drily.

“I daresay, Dick,” he said. “But I’ve a fancy for your company... I shouldn’t like the Colonel to get worrying you just now.”

“You mean,” Denzil said stiffly, “that you distrust me?”
