JTT - it was a fella called John Stalker, who was Deputy Chief Contsbale of Greater Manchester. What a name for a policeman. Anyway, he was getting too close to the truth, obver in Nirthern Irekland, so he got framed by his colleagues for associaiting with someone who was framed and jailed for corruption - and later cleared.

His career as a policeman was wrecked, but he's highly regarded. Here's a page about him, but it doesn't mention much about the Northern Ieland business, because it's meant to get him bookings as an after-dinner speaker, and I suppose a whiff of controversy might get in the way there.
