The protagonist of Chaff is a nameless mercenary.

He receives his orders through steganographic messages sent through the fluorescent tubes and price tags in his local supermarket.

He lives on Wisconsin Avenue in Washington, USA.

He drives a silver 2025 Ford Narcissus.

He's coloured. ("She was sixteen or seventeen, slender, dark-eyed, coffee-coloured, with a faint Latino accent. She could have been my sister.")

He's murdered people with counterfeit Mother before - we witness him killing a girl with it after successfully selling it as 'Southern Rainbow'.

He works for the Drug Enforcement Administration - or at least pretends to as his cover.
