I've been puzzling over H constantly. I mean why are they called H? If it were Osborne, Thurwell or Fairbanks why the H? But of course it would be too obvious to have someone whose name begins with H.... Is it Sunday yet?
They’re not called H. The code name H came from Dot’s dying declaration but at the end of season 5 they decided he actually meant H in morse code which is 4 dots - Steve says something like “four dots, four caddies, four corrupt officers. Hilton, Gill, Hargreaves and one more”
Which is completely bloody stupid, but that’s what the plot says. Also Gill wasn’t a police officer so it doesn’t actually work, and it’s weird that he referred to them as “four caddies”, since none of the people uncovered had anything like Dot’s role. Hargreaves was blackmailed, I think they had something over Hilton too (can’t remember if this was confirmed?) and with Gill Ted said that her retainers must have come with strings, and that she was seduced by the glamour 🙄
But yeah, that’s where we are with “the fourth man”.
I’m trying to remember how Corbett and McQueen came to use the name H - was it Steve that mentioned it first? Or maybe Gill told him in their pre-recruitment chat?
