I didn't like this episode too much when I first saw it, but it's actually very good and well plotted. The juxtaposition of the temple story with that of an exotic dancer, some scenes of which take place in a strip club, is very clever. It also shows up how easy it is to jump to conclusions about people based on initial impressions.
When five monks are killed, initial suspicion falls on everything from the surviving monk to possible gang-related links - then onto discovery of local neighborhood kids who might blame the monks for economic losses. The story is well played out and has a calmness about it, as well as a nicely tied-up ending.
The other story concerns one of Catherine's best friends when they were both stripping together. She was murdered and the murderer caught. It's now fifteen years later and the evidence in the case is due to be destroyed. Catherine wants one last look and what she finds suggests that the case was not watertight and begins to wonder if her mentor who investigated the case missed something - or worse. A good little story too, and one which shows Catherine's character off well, especially in the final scenes.
