It's been a very long time since I've found anything inside one of my books. This one was one of those rare instances that I came across while I was actually reading the book. Tucked into page 79 of my copy of Murder by Request by Beverley Nichols was this:
Transcription: "Dear Major Steeves, Thank you for you order and hope the book is to your satisfaction. I would also like to thank you for your service to the country. Yours sincerely, B Storey
Send cheque (in another handwriting) -- I'm guessing Major Steeves wrote that.
Remember the days when a bookseller would you send a book prior to your paying for it? I met only one person in my lifetime who would agree to searching for a book and send it to a customer trusting that payment would follow.
There is nothing noteworthy on page 79 of the book where I found the note.
