When Robin was in her final year of junior school, a local woman was kidnapped. Stephanie Slater was twenty-five, an estate agent, taken from a house she’d been showing in Great Barr, only a few miles away in the north of the city. It became a major national news story, one of the biggest manhunts in British history. Christine and Dennis whispered about it in the other room, waited ’til she’d gone to bed to watch the news, but the details had been in the air, all anyone could talk about: the ransom money snatched from a railway bridge, the coffin-sized box inside a green wheelie bin in which Slater had been locked in darkness for eight days, told that if she moved she’d be electrocuted. After she was released, she described how she’d talked to Michael Sams, and kept talking, so he’d be forced to understand that she was a person, a human being. Her bravery and presence of mind probably kept her alive.

Michael Sams, badger-faced, wooden-legged Michael Sams – by the following year, when Robin started at the grammar school and met Corinna, he’d become a playground bogeyman, the shadowy figure who offered you the bag of sweets, who shoved you into the back of a van as you walked home from the corner shop at twilight. Michael Sams’ll get you.

And then, two years later, barely fifty miles away in Gloucester, came Fred and Rose West.

She and Rin were twelve turning thirteen by then: prime-time adolescence. It had gone on for weeks, the systematic taking-apart of the house at Cromwell Street where, over decades, Fred and Rose had together raped, tortured and killed young women, including their own daughters. White forensic suits on the news, day after day, week after week, another set of remains and another and another, in the garden, in holes dug in the cellar floor. Again her parents had tried to shield her but away from Dunnington Road, she and Rin had followed the news with a horrified fascination, reading the papers, watching the news at Rin’s place when Di was at work and Will, babysitting, was doing his homework in the other room. There were few stories, thank god, as depraved as that. Rose was found guilty on ten counts of murder; Fred, charged with twelve, never stood trial. He committed suicide while on remand at Winson Green, HMP Birmingham, just a handful of miles up the road. Robin remembered: it was New Year’s Day.

Two of the biggest crime stories of the decade, both local, both sexual violence against young women, a double whammy that happened just as she and Corinna became aware of the news, aware that they were – or soon would be – young women, and that monsters were not just in books but opening their car doors to offer you a lift in the rain.
