Pear Trees and Stately Homes

A lady phoned up yesterday.

"I've just seen your advert in History Today" (Which was over a year ago).

"I've got a copy of "Paradise and the Pear tree" what is it worth?"

Having checked that she means "Paradise and the Peri", I comment that I would need to know when it was published, and by whom to know a value.

"Well how can I know those things - I just want to know if I've made a profit."

Once we get through this one, she changes tack.

"Well in that case, can you tell me when Kingston Lacey house is open?"

Hmmm.
