This was an engaging and enthralling mystery series, with many unexpected developments along the way. Jennifer Ehle was excellent in the title role, and provided the program with a lot of momentum. The entire cast was good, with perhaps the exception of Adrian Dunbar, and the material that they had to work with was first class. Anyone looking for a screen adaptation of the novel will be disappointed, as Alan Beasdale has taken major liberties with his source material - but in my opinion, his version is better than the original. A worthwhile experience - hang in for the whole of the series for an enjoyable time!
