They drank mixed vermouth. Sir Alfred picked up an evening paper from his side.

“Any news?” he asked.

“Nothing fresh,” Granet replied. “The whole worlds excited about this submarine affair. Looks as though we’d got the measure of those Johnnies, doesn’t it?”

“It does indeed,” Sir Alfred agreed. “Two submarines, one after the other, two of the latest class, too, destroyed within a few miles and without a word of explanation. No wonder every one’s excited about it!”

“They’re fearfully bucked at the Admiralty, I believe,” Granet remarked. “Of course, they’ll pretend that they had this new dodge or whatever it may be, up their sleeves all the time.”

Sir Alfred nodded.

“Well,” he said, “come in to dinner, young fellow. You shall entertain me with tales of your adventures whilst you compare our cuisine here with your own commissariat.”

They passed on into the strangers’ dining-room, a small but cheerful apartment opening out of the general dining-room. The head-waiter ushered them unctuously to a small table set in the far corner of the room.

“I have obeyed your wishes, Sir Alfred,” he announced, as they seated themselves. “No one else will be dining anywhere near you.”

Sir Alfred nodded.
