[Harry and Marcus are distracting Mrs. Wilberforce while Louis deals with the Major on the roof] Mrs. Louisa Wilberforce: It won't do any harm to tell you now that Major Courtney has gone to the police. They'll be here shortly. [there is a loud crash from outside] Mrs. Louisa Wilberforce: Oh! Whatever is that? Harry: I expect something fell off the roof, mum. Mrs. Louisa Wilberforce: The roof? Harry: Probably a... chimney-pot. Mrs. Louisa Wilberforce: A chimney-pot? Professor Marcus: See who it is, Harry [pushes Harry out the door]

It won't do any harm to tell you now. Major Courtney has gone for the police. They'll be here shortly. Oh, whatever's that? I expect something fell off the roof. Maybe a chimney pot. The roof! A chimney pot. See who it is, Harry. We'll talk about this when the police get here. It's long past my bedtime, and I've had a most exhausting day. Well, where is he? Where is the major? Is he up there still?
