"And then?"
"I'm afraid they will try another murder. They won't trust a living soul to hold his peace under the circumstances."
"But how are they to know I saw the thing?"
"By your hand. In fact, I think they know already."
"Already?"
"Yes. There was somebody about when we were there, and he was evidently hiding."
"You heard him?"
"Yes. I didn't want to alarm you. I have reason now to be alarmed for myself. They know I am in it. We've got to think quickly and act quickly. The minute that orders come they will try to get us. As long as we stay in public places we are safe. But we must not go out alone any more."
The two went on to the hotel. Saunders glanced back as they were entering the town. His eyes covered the hedge.
"I thought so," he said. "That chap has been dodging in and out of the trees and keeping watch on us. From this point he can see right along the street to the hotel door. It's no use trying to conceal anything now. Our only safety lies in keeping in public places; but they won't strike till they get their orders."
