I've been watching a newish series by Stephen Moffat on my local PBS station: Sherlock
It is pretty good, so I thought I would share. Sherlock is a lot like the darker side of the Doctor. In fact, he explicitly calls himself a "high functioning sociopath" at one point. (A theme Doctor Who explored quite a bit in Seasons 5 and 6). The mysteries are decent enough.
Links are around, or you can watch it on PBS (in America) or the BBC (but you probably would have heard about it by now)
