Review of The Chocolate Box

I've watched nearly every episode of the Poirot series as well as some of the film versions and have loved most of them, but this episode stunned me with its rich, authentic period settings, Suchet's ability to portray the young and the mature Poirot equally convincingly, the graceful, unobtrusive background music -- all in all, I kept thinking I was watching a full-budget movie. I simply loved it and will watch it again to enjoy again the exquisite care for detail that make this such a fine series and this a particularly fine episode. I had just one quibble, that bothered me only because the episode is otherwise so perfect. A jeweled lapel pin worn by Poirot that features in the background story appears to have violet flowers in most scenes, but in a flashback when he first receives it, the flowers look decidedly pink or coral. If anyone can explain this discrepancy, I'd appreciate it, just so I can say, "Utterly perfect"!
