Speculation intensified with the July 2005 publication of "Half-Blood Prince" and the detailed post-publication interview given by Rowling to Mugglenet and The Leaky Cauldron. Notably, DumbledoreIsNotDead.com sought to understand the events of the sixth book in a different way. (Rowling later confirmed, however – on 2 August 2006 – that Dumbledore was, in fact, dead, humorously apologising to the website as she did so.) A collection of essays, "Who Killed Albus Dumbledore?: What Really Happened in Harry Potter and the Half-Blood Prince? Six Expert Harry Potter Detectives Examine the Evidence", was published by Zossima Press in November 2006. Contributors included the Christian author John Granger and Joyce Odell of Red Hen Publications, whose own website contains numerous essays on the Potterverse and fandom itself.
