This is seriously one of the best plotted murder mystery shows if all time whether American or British! I have seen every episode at least 10 times and most of the time even in the 10th I can't remember whodunnit. So it really annoys me when people refer to this show as predictable and lightweight. Sure we know it's ridiculous that where everywhere Jessica goes there's a murder. But we'll if there wasn't there'd be no 12 season gem of Angela Lansbury's brilliant show.
