Fans of the drama were also quick to express their praise and admiration for Herman Knippenberg, now retired, and his efforts to bring Charles to justice.
"A life's work to get justice for those young people who sadly perished at the hands of this couple. Finding out at the end the stories of the real people involved made it more humbling. Well done. #TheSerpent," wrote a viewer.
Another said: "#HermanKnippenberg incredible resilience, truly heroic in his forensic fight for justice and to save lives #TheSerpent @BBCiPlayer @mammothscreen."
Charles Sobhraj was played by Tahar Rahim
The eighth episode jumped forward in time by a number of decades to 2003. At the time, Charles took the decision to return to Nepal – a decision which many believe was to boast his presence to authorities – before it became evident to Herman and the police that they finally had enough evidence to capture him once again.
The finale also explained what happened to Marie Andree-Leclerc, who returned to the Quebec shortly before her death from cancer in 1984, Ajay, who was never seen again, and their neighbours Nadine and Remi, who relocated to Thailand.
