A mysterious stranger visited a story called Tom Brown's Schooldays. That meant a mission for me. I'm Jam Rodger, and I'm a Guardian: it's my job to stop people from spoiling stories. I went to Tom Brown's Schooldays, and hid in the study of a bully called Flashman. I overheard him plotting with the stranger to cause trouble for a girl called Alice. But there were three girls called Alice – in Alice in Wonderland, The Children of the New Forest, and The Treasure Seekers. Could I guard them all?
