What is the ruby redfort code?

Each code needs a keyWord to decipher it. The keyWord in the first book is double and the one in the second book is whale. To use the keyWord, you need to use a Caesar shift. For example, if my keyWord was book then the first letter would use a Caesar shift where A became B and B became C etc; the second letter would use a Caesar shift were A becomes O and so on. It is easiest to go to rubyredfort.com and go to Ruby's room and to the code-breaking section where it will show you how to work it out, and if you get really stuck you can use the code-breaker app they have.
