Murdoch in Wonderland

At a costume party held in honor of the late Lewis Carroll, a woman is found murdered and all clues point to a man dressed as the Mad Hatter. It seems obvious that the "Hatter" is the killer, however this is not welcomed news as this part was played by Murdoch himself. With Murdoch being the "Alice In Wonderland" prime murder suspect, it’s up to his team to prove that their favorite detective is not the killer...but can they really be sure?
