Writers talk about who they “see” as their characters when they are creating. When I am writing Holmes, I see different actors as Holmes, depending upon the story. But every time, it is Clive Merrison I hear as the great detective.
Merrison, with Michael Williams as Watson, performed radio dramas of the entire Canon. They are among the best Holmes productions in any media, headed up by Bert Coules. Non-Canonical tales were then recorded, with Andrew Sachs replacing Williams, who had passed away.
Bert wrote 221 BBC, a book about the series, which Wessex Press re-released in a much-revised and expanded edition. It’s a good read.
I enjoy radio dramas and as far as Holmes goes, I don’t expect to see this one surpassed.
