I shall work my way through the rest of Special Branch, as it's been years since I've watched it. Mind you, a quick run down of the back cover lists all the cop show standards: having to guard a brattish Hollywood actress from a stalker (saw that last week on by the Numb3rs), a terrorist attack in central London (de ja news), the boss being done for corruption, a body washing up that looks like a common or garden variety homicide but is anything but, etc, etc. If there are only a dozen cop show plots, then Special Branch has all of them (and what will LoM do after episode #12? Go the KGB tranny, I say).
Okay, so you had to be there, but it was such a LoM moment. Methinks TPTB have this boxset on their bookshelves, too.
