Gadding with Ghouls is a book written by Gilderoy Lockhart. The book was a required textbook during the 1992–1993 school year.[1]
While getting Lockhart to give her permission to get a book in the Restricted Section, Hermione Granger revealed that there is a mention of slow-acting venoms in this book. Later that year, Harry expressed his desire to throw his copy of this book at Lockhart's face for his insistence that Rubeus Hagrid was guilty of opening the Chamber of Secrets.
