You read and read and read about the Victorian era. Who was in government? What was the social status of the country? Why was Holmes a bohemian? Then you start to read Doyle and you sort of sniff it through. After a great deal of study, things begin to happen. Like hands. What does he do with his hands? How would he move? And you whisper, whisper, whisper because you have to find the voice. You keep whispering so the imagination keeps going. When you think you’ve got him - or he’s enough in you - you speak. It’s an enormously exciting process.
