To the public, he’s a hero: a killer who targets convicted paedophiles. Two men are dead already - tortured to death. Even the police don’t regard the cases as a priority. Most feel that two dead paedophiles is a step in the right direction. But to DC Maeve Kerrigan, no one should be allowed to take the law into their own hands. Young and inexperienced, Kerrigan wants to believe that murder is murder no matter what the sins of the victim. Only, as the killer’s violence begins to escalate, she is forced to confront exactly how far she’s prepared to go to ensure justice is served….

The teenage girl was the first victim. Her throat cut to the bone, she didn’t stand a chance. Her mother, at least, had time to fight back. Briefly. Called to the crime scene in leafy Wimbledon, Maeve Kerrigan’s first thought is that this is a domestic dispute gone badly. But the husband is found lying bleeding and unconscious in an upstairs room. As a criminal barrister he insists he’s the third victim rather than their prime suspect, even if he’s a man who makes enemies easily. The only other surviving family member is 15-year-old Lydia....

He meets women. He gains their trust. He kills them. That’s all Maeve Kerrigan knows about the man she is hunting. Three women have been strangled in their homes by the same sadistic killer. With no sign of a break-in, every indication shows that they let him in. But the evidence is pointing at a shocking suspect: DI Josh Derwent, Maeve’s colleague. Maeve refuses to believe he could be involved, but how well does she really know him?

COP KILLER STRIKES AGAIN! The tabloid headlines are lurid but accurate. A killer is terrorising London but this time it is the police who are the targets. And Maeve Kerrigan and her boss Josh Derwent are clueless as to why. But it will only be a matter of time before the murderer selects his next victim…

Arson, accident or murder? After a fire rips through a North London tower block, two bodies are found locked in an 11th floor flat. But is the third victim that ensures the presence of detective Maeve Kerrigan and the murder squad. It appears that controversial MP Geoff Armstrong, trapped by the fire, chose to jump to his death rather than wait for rescue. But what was such a right-wing politician doing in the deprived, culturally diverse Maudling Estate?

Leo Stone is a ruthless killer or the victim of a miscarriage of justice. A year ago, he was convicted of the murder of two women and sentenced to life in prison. But now he's free, and according to him, he's innocent. DS Maeve Kerrigan and DI Josh Derwent are determined to put Stone back behind bars where he belongs, but the more Maeve finds out, the less convinced she is of his guilt. Then another woman disappears in similar circumstances. Is there a copycat killer, or have they been wrong about Stone from the start?

Everyone's heard the rumours about elite gentlemen's clubs, where the champagne flows freely, the parties are the height of decadence...and the secrets are darker than you could possibly imagine. DS Maeve Kerrigan finds herself in an unfamiliar world of wealth, luxury and ruthless behaviour when she investigates the murder of a young journalist, Paige Hargreaves. Paige was working on a story about the Chiron Club, a private society for the richest and most privileged men in London. Then she disappeared. 

When a body is discovered at a popular Highland landmark, it seems like just another day on the job for DCI Jack Logan and his team. Except this body is missing a very vital component, and given its location - The Well of Seven Heads - it seems like someone is trying to send a message. But why? And to whom? 

When a young man is found frozen to death on a Highland street in mid-December, DCI Jack Logan initially puts it down to a Christmas night out gone tragically wrong. But, when a postmortem reveals something more sinister, Jack discovers he is dealing with a cold, calculating killer with a long line of victims, a talent for torture, and a perverse sense of justice. 

When Ella Watson, a woman of wealth and status, is brutally stabbed to death in broad daylight, it sends a shockwave through the Lake District community.

Jenny Shepherd is twelve years old and missing. Her teacher, Sarah Finch, knows better than most that the chances of finding her alive are diminishing with every day she is gone. As a little girl her older brother had gone out to play one day and never returned. The strain of never knowing what has happened to Charlie had ripped Sarah’s family apart. Now in her early twenties, she is back living at home, trapped with a mother who drinks too much and keeps her brother’s bedroom as a shrine to his memory. Then, horrifically, it is Sarah who finds Jenny’s body....

Was the biggest case of his career the worst mistake he ever made? Ten years ago, DCI Jack Logan stopped the serial child-killer dubbed "Mister Whisper", earning himself a commendation, a drinking problem, and a broken marriage in the process...When another child disappears a hundred miles north in the Highlands, Jack is sent to lead the investigation and bring the boy home. But as similarities between the two cases grow, could it be that Jack caught the wrong man all those years ago?

After a scandal forces DI Kelly Porter out of the Met, she returns home to the Lake District. Crimes in the Cumbrian constabulary tend to be minor, but Kelly begins work on a cold case that shocked the local community - the abduction and brutal murder of a 10-year-old girl.

One who has killed before - and will do so again. Kevin Flint is a young man with no friends and a reputation for being odd. He explores the hidden corners of the Lake District and likes to creep and watch. He witnesses depravity and it excites him. But will he cross the line from bystander to perpetrator?
