I haven't had the pleasure of viewing it, has it been on long?
It's been running once a year,for about 12 episodes each year,on A&E.
It's available for sale on DVD through the BBC website,but I got the DVD's from my public library and they are better than the A&E productions because they are not chopped for commercials.
If you ever get a chance to see it I know you'll enjoy it.
