During the Troubles the IRA set up a unit to find informers within its organisation.
Informally called the ‘nutting squad’, it was led by Freddie Scappaticci, the son of an Italian immigrant who grew up in the Markets area of Belfast.
He used kidnap, torture and murder to flush out alleged informers.
But Scappaticci, one of the highest ranking men in the IRA, was himself an informer in the pay of British intelligence, operating under the codename Stakeknife.
Last week, the news broke that the former IRA man had died several days earlier.
During his final years, he was being investigated by Operation Kenova, an inquiry set up in 2016.
Its findings are due out later this year. But how will his death impact the inquiry and the families of his victims who are still seeking justice?
