From IMDB:

Detective Superintendent Steve Fulcher intends on catching a killer of a missing woman, even if that may cost him his career and reputation.

From Amazon Prime you can stream the 6 episodes of this true  one season British TV crime story. Each episode lasts about 45 minutes.

Using carefully researched material, this series documents a true, riveting, and frustratingly sad case in which DS Steve Fulcher of the Wiltshire police district successfully finds a serial killer only to have his career destroyed because he made a brave and clever decision that did not completely follow guidelines.

Do not be put off by the word “documentary” because this series is a very well done enactment that is anything but a presentation of dry facts.  All the characters come to life in moments of grief, anger, loneliness and love.   Wiltshire police department concern with public relations is maddening and, thanks to this series, fully exposed.

Once again there are many familiar British actors:

• For me the biggest surprise was the appearance of the actor Joe Absolom who plays the serial killer Christopher Halliwell.  You may recognize him as the young man Al Large who was the son of the very LARGE Bert Large in Doc Martin.  He seems so much older in “Confession” and plays the part of a clever, intelligent but stricken serial killer very well.
• Siobhan Finneran (who plays Elaine Pickford) played Clare Cartwright in the wonderfully unhappy series Happy Valley. Her acting resumé is enormous.
• Imelda Staunton (who plays Karen Edwards) is another seasoned British actor with a huge resumé.  Her role as the abortionist Vera Drake was remarkable.

Sorry for the “Do Not Miss” inflation, but DO NOT MISS!
