Favourite male character.
That's pretty much impossible to answer, there's so many of them.
As good as every character Dick Francis wrote, but stand-out ones are Sid Halley, Roland Britten, Philip Nore and Kit Fielding. Of course Tony Hill from Val McDermid's crime series. Dyan Ardais and Lew Alton of the Darkover series. Camber MacRorie, Rhys Thyrin, Allister Cullen, Duncan McLain and Denis Arilan from the Deryni series. Elijah Bailey from Asimov's Robots. Or how could I leave out lovely Colonel Brandon? Or Sidney Carton? Poor Edward Johnson?
The list is quite long ;) Much longer than this.
