This two-part true crime documentary unveils the shocking 33-year investigation that ultimately brought the depraved murderer David Fuller to justice. Exposing his dark sexual secrets, the case earned him the chilling moniker "The Monster in the Morgue."

It all began on June 23, 1987, when Wendy Knell was found brutally beaten to death, sparking a manhunt. Just five months later, Caroline Pierce went missing from the same neighbourhood in Tunbridge Wells, UK. Detectives suspected the same man was responsible for both crimes.

For three decades, the victims’ families and friends lived in fear as the killer evaded capture, all while continuing his twisted crimes behind closed doors.

Then, in 2020, the unimaginable happened. David Fuller was finally arrested, but the hunt for a double murderer was only the beginning. The investigation into his horrific crimes—far more prolific than anyone could have imagined—was just starting to unfold.
