Anna and Reid weren't meant to be, apparently. She's a fiery American journalist; he's a stoic British detective - it was nice while it lasted, and then it really wasn't.

And Anna is over it now anyway. She's on the scent of a career-making story - a suspicious death amongst the cloistered elite world of Cambridge University, with a slice of police corruption too.

It's just, the more she investigates, the more there's only one person she wants to talk to about it. She starts writing Reid a long sprawling email - it's not like she's ever planning to send it.

Until suddenly, she's in desperate trouble. The problem with chasing a killer is that sometimes, you run right into them.

And the only detective she can trust with her life, is the one who broke her heart...

Someone in your family isn't who they say they are... Aisling's two sons, Ethan and Finn, mean everything to her. Ever since becoming estranged from her own parents, though, she's always felt like a piece of her is missing. Desperate to find answers - about her family, and herself - Aisling uploads her DNA to an ancestry website, and is thrilled when it finds a match.

But instead of finding answers, she comes face to face with a detective. Aisling's DNA is a match for a recent crime scene - the latest in a string of murders by a dangerous serial killer, known as 'the bonfire killer'. And the police have three lead suspects: her father, or one of her two sons. Aisling would do anything for her family - but can she protect a killer?

Louise wakes up. Her head aches, her mouth is dry, her memory is fuzzy. But she suspects she's done something bad. She rolls over towards her husband, Niall. The man who, until recently, made her feel loved. But it's not Niall who's lying beside her. In fact, she's never seen this man before. And he's dead . . . As Louise desperately struggles to piece her memories back together, it's clear to Detective Jonah Sheens and his team that she is their prime suspect - though they soon find she's not the only one with something to hide. Did she do it? And, if not, can they catch the real killer before they strike again?

Detective Jonah Sheens is enjoying a moment of peace and quiet, when a teenage girl wanders out of the wood.

She's striking, with flame-red hair and a pale complexion.

She's also covered in blood.

She insists she's fine. It's her sister he needs to worry about.

Jonah quickly discovers that Keely and her sister, Nina, disappeared from a children's home a week ago. Now, Keely is here - but Nina's still missing.

Keely likes to play games. She knows where her sister is - but before she tells, she wants Jonah's full attention.

Is she killer, witness, or victim? And will Jonah find out what Keely's hiding, in time to save Nina?

Aidan Poole logs onto his laptop late at night to Skype his girlfriend, Zoe.

So why is he so hesitant to call the police? When his messages finally reach them, DCI Jonah Sheens and his team take the case. And discover the body...
