"And a few of you need to read Wanderings with Werewolves more carefully - I clearly state in chapter twelve that my ideal birthday gift would be harmony between all magic and non-magic peoples - though I wouldn't say no to a large bottle of Ogden's Old Firewhisky!" - Gilderoy Lockhart (CS6)
Supposedly autobiographical tales of bravery and skill out in the dangerous world.
One of the many required textbooks for Defence Against the Dark Arts in Harry's second year (CS4). Perhaps the encounter which Lockhart claimed to have had with the Wagga Wagga werewolf is described in this book.
Part of the answer to question 54 on the first quiz the second year students take in Gilderoy Lockhart's class (Lockhart's ideal birthday gift) can be found in chapter twelve of Wanderings with Werewolves (CS6).
