"To do with a future regeneration of myself having too much to drink and dictating half a dozen sonnets that he shouldn't have during the post-production party for Much Ado About Nothing. A little quoting is a dangerous thing." The Doctor sighed. "And let's not even go into the whole business with the Fourth Murderer in Macbeth."
Ace frowned. "What fourth murderer?"
"Precisely."
