Review of the previous season.

Sherlock (Jonny Lee Miller) is suffering from post-concussion syndrome following a blow to the head in the previous season. At a meeting, he meets Michael Rowan (Desmond Harrington), another addict who thanks him, and credits Sherlock's words for keeping him sober. Then he offers to help Sherlock - and by the end of the episode we find out that Michael is a serial murderer. I realized immediately that he would be the boogeyman for the whole season. While I was right, he shows up less than I thought, but enough to cause all our main characters a lot of grief.

Not the best season (1 and 2 hold those titles) but not too bad, although it did feel a bit like going through the motions.
