“Come out again,” said Bill helpfully.

“Yes; but which end?”

Bill sat up with a start.

“By Jove, you mean that he will go out at the far end by the bowling-green?”

“Don’t you think so? Just imagine him walking across the lawn in full view of the house, at midnight, with a body in his arms. Think of the awful feeling he would have in the back of the neck, wondering if anybody, any restless sleeper, had chosen just that moment to wander to the window and look out into the night. There’s still plenty of moonlight, Bill. Is he going to walk across the park in the moonlight, with all those windows staring at him? Not if he can help it. But he can get out by the bowling green, and then come to the pond without ever being in sight of the house, at all.”

“You’re right. And that will just about give us time. Good. Now, what’s the next thing?”
