Return to Groosham Grange is a fantasy novel written by English author Anthony Horowitz and the second novel in the Groosham Grange series. It was first published in 1999 under the name The Unholy Grail, but was then reissued in 2003 under the new name, Return to Groosham Grange. This change in the title was done to help link the two books together. Return to Groosham Grange serves as a direct sequel to Groosham Grange and mainly revolves around a plot concerning a secret agent of the Bishop of Bletchley trying to destroy Groosham Grange once and for all. A second sequel was planned, but Horowitz changed his mind after the success of the Harry Potter series. Plot After initially hating Groosham Grange when David arrived almost a year ago, he has decided to accept it. David now realizes that he belongs to this school and has a new goal. He wants to win the school's top prize, The Unholy Grail. Throughout the year, David had worked hard to earn the most points so he could walk away with the Grail. But three months ago, Vincent King - a new student, had joined the school. Vincent being adaptive, quickly earned points and then stood second in line behind David to win the prize. Seeing Vincent as a rival, David had an instantaneous dislike to the new boy, even though Vincent became very popular. Finally, when the year was coming to an end and only one test was left (i.e. "Advanced Cursing"), David is relieved to hear that he still has a 30-point lead over Vincent. One day, David witnesses Vincent exiting a tall tower. When David tries to enter the tower, he is spotted by Gregor, the school porter and is thus forced to return to his classes. Convinced that Vincent is up to something, David wants to know what is inside the tower. Being held up by Gregor causes David to be late in class and he loses three points, which gives him a 27-point lead over Vincent. Afterwards, David starts a fight with Vincent and loses nine more points. But that night, David awakens and notices that Vincent's bed is empty. In the hallway, he thinks he sees Vincent sneak into Mr. Fitch and Mr. Teagle's office. When David enters the room, no one is there except Mr. Fitch and Mr. Teagle who are sleeping on the bed.
