“Stella Mendoza—not a bad girl and not a good girl,” he said. “I’ve been wondering why Penne always gave us permission to use his grounds for shooting, and now I know. I tell you that that house holds a few secrets!”

Michael smiled faintly.

“One, at least, of them will be revealed to-night,” he said. “I am going to explore Griff Towers, and I do not intend asking permission of Sir Gregory Penne. And if I can discover what I believe is there to be discovered, Gregory Penne will sleep under lock and key this night!”
