"Well," said Captain Bob, rising, "I think it's the weather that has given you the hump, old chap. Still raining," and he glanced at the windows. "What do you say to a game of billiards? I'll play you three hundred up if you like."

"With all my heart," replied Van Drissel, getting up with a limp and opening the door for Mrs. Dashwood, and the two officers went into the billiard-room, whence they were no more seen for a couple of hours.

"Hard luck," said Bob Dashwood at last, as the Belgian missed an easy shot. "And you've left them for me, too. I'm afraid your leg is worrying you."

"Oh, that is nothing," replied his companion with a wry smile, as he limped towards the scoring board. "You only want five to win."

"And there they are," said Bob apologetically, as the white ball followed the red into a pocket. "But, you know, you're playing a very good game."

"It is nice of you to say so," replied the Belgian. "Unhappily, I have so much time for practice these days," and he lit a cigarette. "There is not much news in the papers this morning."

"The calm before the storm, my boy," smiled the captain with a twinkle of his grey eyes. "There will be some big news directly. By Jove! you ought to see the munitions they're piling up behind us. It is incredible! The worst of it is, our sector simply swarms with spies, and the beggars get to know everything almost as soon as we know it ourselves; in fact, sometimes before.

"They're very slick," the captain went on. "As a matter of fact, Germans often come over into our lines in British uniforms, and they are so thundering clever that you can't tell the difference. Why, not long ago, I yarned for half an hour with a major of the R.E., as I thought—didn't tell him much, luckily, but we hadn't parted five minutes when he was 'wanted,' and there was no end of a hunt, but he managed to get clear, and a genuine English major was within an ace of being shot in mistake for him if he hadn't been recognised by one of the staff in time."

"Ah, there you are," said Van Drissel. "When do you think Sir Douglas Haig will make a move?"

"Almost directly," said Captain Bob. "The day before I was wounded I had it on first-rate authority that—— Hallo! here's my young brother. Excuse me, Van Drissel," and without further ceremony he darted into the hall as a lad in the uniform of the O.T.C., who had just got out of a taxi, flew up the steps three at a time and dashed in with a shout.
