Simon Shuker's Code-Cracker Volume Six is now available, and although Volume Three has sold out, we still have limited quantities of the other four books in the series, so be in quick!

You should be able to buy the sixth volume from the same place you bought the other books: to help you here is the list of shops that have previously purchased copies. If the books aren't in your local store, they can order in copies - the distributor details are available here. Have fun!
