EE British Academy Film Awards - Red Carpet ArrivalsNever mind staring at a block of ice for an hour (*cough*GameofLame*cough*), this is how you get fans involved in a big announcement.

J.K. Rowling has close to 10 million Twitter followers, and she gave them a Hermione-level riddle to solve to get the title of her next Cormoran Strike book. This was after making it clear she would not be holding a ("bloody") referendum to decide the title of the next "Fantastic Beasts" movie, although that title is currently being decided by others.

A fan asked if she had any news on the next Strike novel, to follow "The Cuckoo's Calling," "The Silkworm," and "Career of Evil," all written under Rowling's pseudonym, Robert Galbraith. Rowling answered, "It isn't finished, though well underway!" Another fan asked for a hint on what the novel will be called, and that's when she started this hangman game:

As you can imagine, fans had A LOT of fun coming up with guesses, and while most were wrong, a winner was eventually declared.

Then someone got it:

Congratulations to that quick-thinking fan! But what does "Lethal White" mean as a title for the detective series? As Moviepilot speculated, "A quick Google search reveals that lethal white is actually a rare but serious genetic mutation found in horses, which can cause foals to die very early on in their lives. Sure it's very specific, and unlikely to be related because Strike and Robin mainly frequent urban areas rather than the countryside. Then again, Rowling's other Strike novels feature animals in their titles. Plus, the titular Cuckoo and Silkworm were crucial to their respective plots, so we definitely can't rule this link out completely."

Fans can look forward to more details on that book, and -- apparently -- the title of the next "Fantastic Beasts" movie, whenever they make a decision.
