He shook his head. “I’m sorry,” he said, “but I am not as eagle-eyed as you two. I saw nothing suspicious.”

“But I saw him watching us several times,” insisted Paul.

“I saw him only once,” added Jack.

“Well, you two may be right and I wrong,” commented the third companion.

“Who do you think it could be?” asked Jack. “And what do you think his purpose is?”

“How should I know?”

“Do you think it is that man I followed last night?”

Paul hesitated for a moment then shook his head. “No, and I will tell you why. The person you followed last night was tall and gaunt. This individual appeared to me to be about average height and robust. I could tell that from the shadow.”

“Shall I turn around and see if we are being followed?” asked Ken.

“No, don’t do that,” warned Paul. “He might catch on that we know we are being followed. I have a better plan.”
