Joyce Fegan: Will Sophie Toscan du Plantier and other murdered Irish women ever get justice?

Pierre-Louis Baudey-Vignaud as a child with his mother Sophie Toscan du Plantier. With so many eyes now on Sophie's case, one would assume there would be some chink or break in the case, because if we aren't watching or listening to these documentaries for justice, then what are we watching them for?

The unsolved murder of a woman just outside her own home 25 years ago is the subject of two highly publicised documentaries released in the space of 10 days. The mystery still captures the public’s imagination after all these years and leads to extensive coverage about the case.
We will sit as armchair detectives, speculating and analysing all available evidence, but will Sophie Toscan du Plantier, who was brutally killed at the end of her lane, and whose body was left out in the winter cold for 24 hours afterwards, ever receive justice?
