He attacked her before evading capture
Chronology
Delia Balmer, an agency nurse, met Sweeney, who confessed to killing his ex-girlfriend.
Based on a true crime story
Balmer rebuilt her life to confront Sweeney seven years later after he was arrested for another murder..
The bodies were dumped in canals in Rotterdam (not Amsterdam) and London
I'm not usually a big fan of these TV four-part dramas that seem to be in vogue at present as they often veer into the absurd but decided to give this a go as it was based on true events and was most certainly not disappointed.
Overall, it was a bit clunky, had to cover a long time period and some of the other acting of the minor characters was a tad wooden but it did not spoil my enjoyment
Anna Maxwell Martin's performance as the key character was exceptional and even though she was the 'victim' she came across as an extremely difficult person to like and didn't do much to help herself.
I thought it was excellent TV and despite my negative opinion of Balmer, Sweeney is the unequivocal monster here
It'll be interesting to watch the documentary with the real Delia Balmer to see if she comes across as prickly and abrasive as portrayed in the dramatisation – which she was even before her ordeal.
