"It's impossible for me to be wrong. I could never mistake the sound of the wireless for anything else."
"And it's there on the roof of this château, which belongs to us by right of occupancy, chattering away to German forces elsewhere!" said Carstairs in an indignant whisper.
"It's doing a lot more than chattering," said Wharton. "They wouldn't install a wireless on the roof of a house at this time of the night, merely for a little idle summer conversation. You saw that a prince and generals came here, and undoubtedly they ordered it done."
"Whatever they're talking about," said Carstairs, "it's not likely they're talking about us, so now is our chance to slip away."
"I'm not going to leave the château just now," said Wharton.
"Then what are you going to do?"
"I'd like to see the wireless on the roof and the man who is working it."
John glanced at Wharton. The light was very dim, but he noticed a spark in Wharton's eye, and he knew that something unusual was working in the back of his head.
"I think I'd like to have a look at the roof myself," he whispered.
"If you chaps are bent on going up there," said Carstairs, "I'm bound to go with you. But we'd better keep our automatics in our hands."
