She heard no sound of voices; it did not sound as though anybody were inside, and sure enough when she opened the door she found nobody in the room but John.
He grinned at her in a friendly fashion. "Where's Gracie?" he asked.
"I don't know," Joey said. She took some credit to herself for not adding, "I don't care."
John laughed. "Well, come and talk to me till she comes along."
Joey established herself on a chair by his sofa. "What do you do when you're a snotty?" she asked. "We know more about the Army, you see."
"Keep a look out when the deck's all ice, mostly," John said. "Of course, sometimes there was a scrap—not half often enough, though—and when you get your signal you've to be jolly quick or the other chap snaffles it all!"
"How do you signal?" Joey asked.
"Wireless mostly. Of course you have to know all kinds of signals. Can you read Morse?"
"No, I can't."
"I'll teach you—it's as easy as winking."
