1x01 Case Histories Part 1
1x02 Case Histories Part 2
Adaptation of Kate Atkinson's novel -- she's having a good month! Pretty decent, though the best thing about it was the cute little dog owned by the sisters... so why did they kill him off?! Poor doggy.
For the interested, the official BBC site (linked above) has a tonne of articles about the series, many more than they normally bother with.
