"I can walk all right now," he muttered. "My God, we'll give these fellows hell for this!"

They made their very difficult way across a plot of ground from which a row of dilapidated cottages had been razed to the ground. The fog still hung around them and seemed to bring with it a curious silence, although the dying traffic from one of the main thoroughfares reached them in muffled notes. Lutchester climbed to the top of a pile of rubbish and then, turning around, held out his hand.

"Up here," he directed.

Graham struggled up until he stood by his companion's side. The latter stood quite still, listening for a moment. Then he climbed a little higher and swung around, holding out his hand once more.

"I'm on top of the wall," he said. "Come on."

Graham's knees were shaking, but with Lutchester's help he staggered up and reached his side. On the pavement below a man in chauffeur's livery was standing, holding out his hands, and by the side of the curbstone a closed car was waiting. Somehow or other the two reached the pavement. Lutchester almost pushed his companion into the limousine and stepped in after him. The chauffeur sprang to his seat and the car glided off. Graham just realised that there was a woman by his side whose face was vaguely familiar. Then the waves broke in upon his ears once more.

"I was right, then, it seems," Pamela observed approvingly. "You were just the man for this little affair."

Lutchester sighed.

"Unfortunately," he confessed, "a messenger boy would have been as effective. I stumbled over to the chapel—rubber shoes, you observe," he remarked, pointing downwards—"and soon discovered that blinds had been let down all round and that there were people inside. There was just a faint chink in one, and I caught a glimpse of several men, your friend Oscar amongst them. Having," he went on, "an immense regard for my personal safety, I was hesitating what means to adopt when the lights were lowered, and it seemed to me that the men were disappearing."

"Do go on," Pamela murmured. "This is most exciting."
