Detective Karen Hart

When two young girls disappear from their primary school, the village of Heighington is put on high alert—and not for the first time. Called in to investigate, Detective Karen Hart is sure that parallels with a previous disappearance are anything but coincidental. DS Hart is still reeling from a case she tried and failed to solve eighteen months ago, when a young woman vanished without a trace. She’s no nearer to the truth of what happened to Amy Fisher, but with two children missing now, too, the stakes have never been higher.

When decomposed human remains are discovered in a suitcase behind a locked door in the home of an elderly man, Detective Karen Hart thinks the facts speak for themselves. That is, until she finds the warning: It’s time to pay for your crime. The body belongs to a former teacher, Oliver Fox, who vanished from the village thirty years earlier. Hart’s instincts tell her there is something untoward about this rural Lincolnshire community—especially when she uncovers evidence suggesting that, although Fox was a victim, he certainly wasn’t innocent.

A man is found bludgeoned to death in woodland by the village of Canwick, and the close-knit community is sent into shock. Detective Karen Hart, still haunted by the tragic loss of her husband and daughter nearby, is brought in to investigate the horrific murder. It soon becomes clear that dark secrets lie behind Canwick’s unspoiled appearance. When Hart begins to suspect that a modern-day slavery ring has been hiding in plain sight among the villagers, she faces a race to find proof before the culprits slip from her grasp.

When two teenage girls vanish without a trace from an educational retreat at Chidlow House in Lincolnshire, the students and teachers are put on high alert. Called in to investigate, Detective Karen Hart questions everyone who came into contact with the two girls, Cressida and Natasha, in the days leading up to their disappearance. Stories of Chidlow House being haunted abound, but Hart - still coming to terms with the suspicious circumstances surrounding the tragic loss of her own family - knows that while the house might be otherworldly, the crime is grimly real.

When Detective Karen Hart hears a scream echoing out of beautiful Lincoln Cathedral one snowy evening, she is the first officer on the scene. In the chapel a man lies murdered, a bloody cross carved into his forehead. A note to the police from the murderer, signed by "The Cleanser", confirms their worst fears: this sadistic slaying is the first of many. When early leads become dead ends, Karen starts to wonder if there’s a link to a rumoured conspiracy within police ranks - particularly when an abrasive new officer is assigned to the case.

When a woman is abducted from a quiet suburban street and bundled into the back of a white van, the only witness to the crime is a child with a reputation for telling tall tales. The police doubt the girl’s story, except for Detective Karen Hart, who is determined to follow her instincts—perhaps because the shy little girl reminds her of the daughter she’s still grieving. When a playing card is found at the scene, Karen finds her first clue. And when a second card is found at the home of a missing woman, Tamara, Karen finds her victim. 

Detective Karen Hart is finally getting her life back on track—enjoying her new relationship and dealing with the grief in her past. Then someone from her counselling group asks for help locating a missing friend, Phoebe Woodrow, who went out partying and never came home. Karen wonders if Phoebe’s disappearance might be related to a recent spate of women having their drinks spiked. As she digs deeper, she finds out that Phoebe’s work in medical research involved a shifty alliance with Quentin Chapman, a menacing local gangster—but it was also about to make her a fortune.

DC Sophie Jones was in the wrong place at the wrong time. Viciously bludgeoned one night in a dark alley, she is left fighting for her life in hospital, leaving no clues as to why she was there or what might have motivated the attack. For Detective Karen Hart, fiercely protective of her young protégée, this is already deeply personal: an attack on Sophie is an attack on the whole team. When a car workshop near the crime scene is linked to local mobster Quentin Chapman, the man Hart has spent years trying to bring down, it’s hard not to jump to the most obvious conclusion.

A family outing to Tattershall Castle comes to a chilling end when eleven-year-old Tommy Burton disappears without a trace in broad daylight. All that remains in his place is a small blue teddy bear. DS Karen Hart and her team are called in to investigate the unusual circumstances—but for DI Morgan the crime scene is eerily familiar.
