So when I was taken to meet the man who was on speaking terms with the great lion Aslan, I subconsciously expected him to be wearing silver armour and carry a sword.
“But he was the antithesis of what I had imagined ”“ a stooped, balding, professorial gentleman with unbelievably shabby clothes and nicotine-stained fingers.
