There is a wonderful scene in which a world weary Barnaby says that he can't stand villages. I have to say I would go along with that. The body count alone would rather put one off.
That aside, this series perfectly captures the many subtle levels of village life, from the curtain twitching to the rivalries. There are times when it does rather overdose on the bucolic detail, but generally the observations are spot on.
The plots and sub plots are generally well worked out, with just enough twist to keep you guessing but not too frustrated through to the end. Well worth a look for the whole package.
