Sherlock star Martin Freeman will unveil his own sleuthing skills in ITV’s new detective drama A Confession.

Here’s everything you need to know…

What is A Confession about?


The series tells the real-life story of Detective Superintendent Steve Fulcher, who deliberately breached police procedure and protocol to catch a killer in a move that ended up costing him his career and reputation.

A Confession, which is set in Wiltshire, sees Fulcher delve into the disappearance of 22-year-old Sian O’Callaghan in 2011, who never arrived back at her boyfriend’s house where she was due to stay after a night out clubbing.

The investigation soon involves Karen Edwards, a mother whose daughter Becky also disappeared years before, and the two cases become connected, leading police to local taxi driver Christopher Halliwell.

However, in trying to rescue both girls, Fulcher breaks numerous protocols when interviewing the suspect.

“I found this is a fascinating story to tell on a number of levels,” said writer Jeff Pope. “On one hand it is a brilliant piece of detective work, but in order to find both girls Fulcher felt he had to deny Halliwell his rights as a suspect.

“It brings into question how we want our police to behave when someone goes missing. Should Fulcher have been praised as a courageous officer fighting for the life of a girl, or lose his career for riding rough shod over the law?”
