Well .. that just jumped onto the site as I was writing it out .. go figure.
Brit .. I rewatched Unforgotten again and counted up the sub plots ( or red herrings ) plots by another name. Counted 4 in all.
1. Focused on a worker at de gaulle Airport in France .
2. Young drug addicted couple .. he's also a purse snatcher.
3. Old guy who got the bad medical report , who likes playing ping pong .
4. Middle aged couple looking for backers in their restaurant business.
Nothing ( at this point ) ties any of the 4 to the body in the chimney found in London . The first Ep. just introduced us to them. Second Ep. should start filling out more .. hopefully start unwrapping the red herrings from the leads.
Liked the interviews with the director and cast at the end .. same for Van der Valk.
