Art on the Underground

Art on the Underground want to use extracts from my novels Frantic and Crushed in a book called "Piccadillyland", which will be distributed at both ends of the Piccadilly line (Heathrow Terminal 1,2 & 3, Cockfoster and Uxbridge) between June and December. Extracts from my books were chosen because I happened to mention several Piccadilly tube stations in my prose. Somebody who works for London Underground must have read my books thoroughly to discover this information, info which I had completely forgotten I had written! The book will contain extracts from 120 authors, so I presume they all wrote about stations on the Piccadilly line ..... I would love to know which employee on the London Underground has taken time out to read all these books.
