“Yes, I see. But why were you so certain of the particular place?”

“Well, he had to mark the particular place by some book. I thought that the joke of putting The Narrow Way just over the entrance to the passage might appeal to him. Apparently it did.”

Bill nodded to himself thoughtfully several times. “Yes, that’s very neat,” he said. “You’re a clever devil, Tony.”

Tony laughed.

“You encourage me to think so, which is bad for me, but very delightful.”

“Well, come on, then,” said Bill, and he got up, and held out a hand.

“Come on where?”

“To explore the passage, of course.”
