I'm about to start reading a book about "The World's End Murders" anyone who's Scottish, will have heard of the infamous case and the fact it took several decades and two trials to convict Angus Sinclair of Murdering Christine Eadie and Helen Scott.
The name Angus Sinclair probably isn't as well known as other Scottish serial killers, Ian Brady, Dennis Neilson, Robert Black, Peter Manuel and Peter Tobin.
However Sinclair has been convicted of killing four women and girls and is suspected of killing many more.
If the evil bastard had been kept locked up for life for his first murder in 1961 (He raped and killed a seven year old girl) a lot of heartache could have been prevented.
