"I don't know, but I think it's possible. I may be wrong, in which case I'll eat my disbelief, and go about henceforward swearing there are such things as ghosts."

"Yes, that's all very well," objected Celia, "but why on earth should anyone want to make ghost-noises and things at us? And who could have done it? Neither of the Bowers would, and how could anyone else get into the house without us knowing?"

"Easily," said Charles. "There's more thann one way in, besides windows."

"That quite decides me," Mrs. Bosanquet announced. "No one is a greater believer in fresh air than I am, but if I am to remain in this house, I shall sleep with my windows securely bolted."

"I still don't quite see it," Margaret said. "I suppose it would be fairly easy to get into the house, but you haven't explained why anyone should want to."

"Don't run away with the idea that I'm wedded to this notion!" Charles warned her. "I admit it sounds farfetched, but it has occurred to me that someone for reasons which I can't explain - may be trying to scare us out of this place."

There was a short silence. Celia broke it. "That's just like you!" she said indignantly. "Sooner than own you've been wrong all these years about ghosts you make up a much more improbable story to account for the manifestations. I never heard such rot in all my life!"

"Thank you, darling, thank you," Charles said gravely.

"Hold on a minute!" interrupted Margaret. "Perhaps Chas is right."

Celia almost snorted. "Don't you pay any attention to him, my dear. He'll tell us next it's the man who wanted to buy the Priory from us trying to get us out of it."
