The sisters agreed it sounded perfect and exactly the restorative holiday they needed. But within a month of arriving, under the supervision of Doctor Linda Burfield Hazzard, Claire and Dora began to realise the frightening truth – they were not patients but prisoners at the isolated sanitorium.

I order another bourbon, neat. This is the drink that will flip the switch. I don’t even know how I got here, to this place, to this point. Something is happening to me lately. I’m drinking too much. My sheets are soaking wet when I wake up from nightmares of decaying corpses. I order another drink and swig it, trying to forget about the latest case I can’t shake. Crime solving for me is more complex than the challenge of the hunt, or the process of piecing together a scientific puzzle. The thought of good people suffering drives me to the point of obsession.

In November 1987, a young couple on an overnight trip to Seattle vanished without a trace. A week later, the bodies of Tanya Van Cuylenborg and her boyfriend Jay Cook were found in rural Washington. It was a brutal crime, and it was the perfect crime: With few clues and no witnesses, an international manhunt turned up empty, and the sensational case that shocked the Pacific Northwest gradually slipped from the headlines.

Worshippers stream out of an Midwestern synagogue after sabbath services, unaware that only a hundred yards away, an expert marksman and avowed racist, antisemite and member of the Ku Klux Klan, patiently awaits, his hunting rifle at the ready. A riveting, cautionary tale rooted in history that continues to echo today, The Killer's Shadow is a terrifying and essential exploration of the criminal personality in the vile grip of extremism and what happens when rage-filled speech evolves into deadly action and hatred of the “other" is allowed full reign.

Roger and Penny Scaggs seemed a poster couple for family values. Evangelical Christians living in booming Austin, Texas, in the mid-1990s, they were respected leaders in their church and community. As Roger diligently worked his way up the high-tech corporate ladder, Penny kept a pristine home and coached similarly devout young women on how to be perfect wives. But on a windy March evening, this godly woman met the devil head-on.

Sharon Marshall was a brilliant and beautiful student whose future was filled with promise—until her murderous, fugitive father drew her into a lifetime of deception that became one of the most baffling cases in the annals of American true crime.

It was a crime that shocked the country. On March 21, 2011, two young saleswomen were found inside a lululemon athletica store in Bethesda, Maryland, one of the nation's wealthiest suburbs. Jayna Murray, thirty, was dead—stabbed, slashed, and struck more than 300 times. Brittany Norwood, twenty-eight, was alive—tied up on a bathroom floor, her clothing ripped, her face bloodied.

But in the summer of 1982 his wife Lynette disappeared and not long afterwards Dawson married a much younger woman, a former student. Less than a decade later this young woman escaped the marriage and went to the police to record her suspicions that Dawson had been involved in Lynette's disappearance.

Over the last decade, a single innovation has massively fueled digital black markets: cryptocurrency. Crime lords inhabiting lawless corners of the internet have operated more freely—whether in drug dealing, money laundering, or human trafficking—than their analog counterparts could have ever dreamed of.
