"Wilson liked poetry, but he absorbed it secretly, like a drug. ... His taste was romantic. For public exhibition he had his Wallace. He wanted passionately to be indistinguishable on the surface from other men: he wore his moustache like a club tie--it was his highest common factor, but his eyes betrayed him--brown dog's eyes, a setter's eyes, pointing mournfully towards Bond Street." (12)

That passionate interest is so far from what I am interested in personally that I can't understand it, but it's such a wonderful description of this character. What kind of mustache does he have, what "club" does he belong to? What is a nondescript mustache in British West Africa in the 1940s?
