"Oh, he's shaved that, has he?" John asked.
"He took it off in the Lab; it wasn't a real one," Joey explained.
John whistled, and grinned approvingly.
"You saw a fair lot through your keyhole! Well, I suppose it's pretty clear that our gentleman was in the habit of altering his appearance for reasons of his own. Another item in his bill. But he didn't show the usual Hun attention to detail—when he took the key out before he had finished everything, did he?"
"He thought no one would know where he was. He forgot Tiddles, I expect," Joey contributed.
John tied the last knot with a flourish, just as the Professor began to show signs of returning consciousness.
"Tiddles? Oh, the Belgian baby! Yes, I expect he forgot her. So she knew you were there."
"Yes; I think she saw my shoe sticking out of the hole I made in the roof, and fetched Frances—the pet!" Joey said. "I say, Gabrielle, do you think I'll be in a fearful row with Miss Conyngham again? for I've done dreadful things in the Lab, besides coming out all untidy."
"I doubt if you'll get it in the neck from your Miss Conyngham this time," John told her cheeringly. "But now we must attend to business. How do you find yourself now, sir? Can you get into my car, or do you want to be helped there?"
The Professor for all answer made a struggle with his hands, but the braid was strong, and John knew how to tie his knots.
