Fox and Foes

My latest piece has gone up here: http://www.firstofthemonth.org/fox-and-foes/

It begins:

Imagine that you are writing a book which opens with your central character, “a powerful, 6’2″, finely dressed man of proud stature and handsome face,” leaping “like a lion” from a bus to save a woman from two knife-wielding thugs. Imagine that, within the next page, you have further described your protagonist as “a musician, and artist… quick in mind and step… (with) and unusual grace of movement… magnetic charm,” and a “creamy” skinned Afro-American, bearing a “noteworthy resemblance” to Clark Gable.
Imagine that your book is a first-person narrative, whose central character is describing himself.
Imagine, further, that your narrative is non-fiction, is, in fact, autobiography. Would it not occur to you, unless you were blinded by pathological narcissism, that this description of yourself might weaken your claim to credibility?
And that this lack of credibility might undermine the purpose of your book, which is to convince others that you are innocent of the murders for which you are serving three life sentences in Alcatraz?
