A quick trawl of some of the greyer websites I use from time to time quickly produces what I want: contact details for an arms merchant who isn't too fussy about inspecting, or even asking for, documentation or licences relating to either his merchandise or his clientele. Online, it seems ideal, but when I arrive at the address, I'm unimpressed.

The proprietor has, apart from a serious case of halitosis, a gold tooth. Why I have no idea. It glints from among a sundry dental collection in black, brown and yellow. Apart of course from the three which are missing altogether from the front. Maybe he lost them in a fight. Or perhaps they ran for cover from their horrible housing.
