A spine-tingling account of the man behind the World's End murders

On October 15 1977, Christine Eadie and Helen Scott left the World's End pub after a fun-filled night with two men in their arms. They had their whole lives ahead of them. They had nothing to fear and everything to look forward to.

Their naked bodies were discovered the following day. They were found six miles apart from each other. No attempt had been made to conceal their bodies, and both girls had been beaten, gagged, tied, raped and strangled.

The case attracted widespread media attention and despite the Police's best efforts, they were unable to identify a culprit. Within the next six months, the investigation was scaled down. The World's End killers were still at large. Free to continue terrorizing the streets of Scotland.

Thanks to the advances in DNA profiling, investigators were able to link the murders of Christine Eadie and Helen Scott to an Angus Sinclair, who was known to the Police.

Sinclair had pleaded guilty to culpable homicide of an eight-year-old girl when he was just 16 and was serving a life sentence for the murder of another 17-year-old girl. It is not known how many victims suffered at the hands of Sinclair. He is thought to have killed at least another four women but it could have been twice that amount.

Best-selling author Ryan Green assumes the role of Angus Sinclair and attempts to fill in the blanks on one of Scotland's most notorious serial killers. Sinclair is a shocking true story about lust, manipulation, dominance and extreme violence.
