Minority Report Easter Egg - Pre-Cog Detectives

In the movie "Minority Report", the three pre-cogs are named Arthur, Dashiell, and Agatha. The significance of the names of the pre-cogs is that they are all names of famous detective novels. Sir Arthur Conan Doyle, Dashiell Hammet, and Agatha Christie. I thought this was pretty cool, and its not obvious to someone who hasn't read any works of those writers.
