Inspector, James Xavier and others in “Descent”

With all due respect, doctor, I still can't believe with this sinister going's on whitechapel are the work of a man in his 60's. I mean be serious, Dr. Xavier!

You must believe me, inspector! Dr. Nathaniel Essex is responsible for all these crimes!

Every person has seen his butcher agrees that he's the younger man. And, I can't credit a man of science with these... inhuman atrocities!

Essex isn't human, inspector! Not anymore. And after tracking round the world for half my life! I begin to think he never was.

Whoa!

Hey! Move this wagon out of the way!
