Messrs. Swinburne and Black,
My research has shown that your shop has a copy of a book that I'm looking for. The book is the Compendium Spiritum, by A. Wilkes. If you do indeed have this book, I would like to purchase it from you. If not, do you have an idea as to where I could find it? It's very important that I find this book as soon as possible.
Thank you for your time.
Sincerely,
Padma Patil
