I believe my publisher has shown a great deal of faith in me over a lot of years but I'm not prepared to be so arrogant to say that the long-term literary value of my work would compensate them for a financial failure.
I did criminal defense work part-time, and that paid the bills for representing abused and neglected children... and for defending in juvenile court those kids the 'child protective system' had missed when it had the chance.
Anyone who says, 'Books don't change anything,' or - more commonly - that crime fiction is the wrong genre for promoting social change - should take a closer look.
I don't even use italics or boldface; that's clutter, not clarity. Fancy fonts are fine for blogs, just as calligraphy is fine for diaries. But when you're writing for anyone other than yourself, you want to get as universal as possible.
