The Code Book. The Secret History of Codes and Code-breaking by Simon Singh. London: Fourth Estate, first published 1999. 402 pages. Has a name written inside and front cover has a small crease, otherwise good condition. I can combine P&P providing you wait for an invoice before making payment. Log into ebay.co.uk and place the items in your basket, then use the “Request Total from Seller” (do not use the Proceed to Checkout button). I will then weigh your items and send you an invoice. If you are using a mobile app, this facility is sometimes not available and you may need to log in on a desktop or laptop.
