This is a fantastic series for lovers of Agatha Christie and British mysteries in general. I have not read this particular book of Christie's and so am not making a comparison here as some other reviewers have. Some said that this production was too drawn out. I find that there's nothing better than a slow-paced British mystery, with finely drawn characters and evocative period details; one that takes the time to settle the viewer into to the world of those characters and build suspense. I thoroughly enjoyed every minute of it, and expect that I'll watch it again!
