South west train from Surbiton to Clapham junction, overground from there to Willesden Junction and then bakerloo from there to Wembley Central! Seems a bit of a faff, but only about 40 minutes from south west to north west London!
Yeah it's pretty decent all round to be fair. True about the overground, although I checked the route on Citymapper and it seems to think that the Bakerloo is slightly quicker from Willesden. Doesn't matter either way though!
Police and Intelligence in the same sentence, who are you kidding? Half the coppers I've ever known would struggle to find their own dicks in the dark!
