Following on from the launch of The Magic Key on BBC Educational television in September, OUP is publishing its second wave of picture books based on the Magic Key adventure the characters have in each episode. This section of the television show is also due to be broadcast on Children's BBC television soon. Code Calling sees the children transported to an ancient civilisation, where coded messages are all too easy to misinterpret. When Wilma assumes she knows best, it almost ends in disaster. Luckily she realizes in the nick of time that she's misread a coded message and what she thought was an impending battle turns out to be an invitation to a dance! * The Magic Key is to be a major 26 part BBC television series featuring the characters from Oxford Reading Tree. * The Oxford Reading Tree characters are recognized by children in virtually all primary schools, and know and loved by parents and children. * This is the first time BBC Education and BBC children's have jointly invested in a children's TV series.
