“Baas?”

“Did you hear what Hans Vermaak was saying just now?”

“Part of it, sir.”

“Why do you think he wanted us not to go back by way of Klip Poort?”

“I don’t know, sir.”

That Gideon Roux and his confederate were aware that he shared their secret he now believed. They must have waited to watch him, and have seen him come out of the cave; and with this idea the full force of Vermaak’s warning came home to him.
