I was surprised and delighted to be contacted recently by Frank Quinn, the son of one of victims in the Hammersmith Nude Murders case.

This was, of course, the unsolved serial-killer investigation from the 1960s that I cover occasionally on this blog, having first written about it in The Hunt for the 60s’ Ripper.

Frank is the son of Frances Brown, who was the fifth of six women to be murdered.

The killer, who successfully eluded what was then the biggest police manhunt in history, picked up the women in his car or van, strangled them and left their bodies at public spots around west London. Dubbed Jack the Stripper by newspapers, he removed their clothing and jewellery, and sometimes their teeth, leaving few forensic clues for police.

‘The case has dominated my life,’ Frank told me. He feels it has been shrouded in mystery for too long, and is encouraged now that ‘things are coming out’.

Dark Son: The Hunt for a Serial Killer

The BBC4 documentary, Dark Son, followed up the findings in my book earlier this year. This pointed to convicted child killer Harold Jones as the man who should be considered the number-one suspect.

‘I found it an excellent documentary,’ Frank said when we spoke by phone. ‘It’s something I’ve been waiting for a long time. I never thought in my lifetime I’d ever see it happen.’

He is hoping the Met will make a serious attempt to reopen the case. In particular, he thinks they should look into Jones’s employment and driving records.

It is thought the killer may have used a grey Hillman Husky and that he worked on the Heron Trading Estate, where the bodies were stored before being dumped.

‘I’m convinced it was Jones,’ says Frank.
