DI Alex Finn

When a high-rise development in South London catches fire mid-construction, a close-knit team of fire fighters tackle the blaze. The building should be empty, but they find a man, unconscious, next to several cases of money. The fire crew make a fateful decision: leave the man, take the money, quit the service and never speak of this again. But five years later one of them is set alight at his own wedding. Soon after, a second is found in the burnt-out remains of his Maserati. It appears that someone knows what they did. And there are still three firemen left to go....

It felt like any other evening before Karl and his daughter were ambushed by a figure in a blank mask. A knife is put to her throat and Karl is forced to make an impossible decision. Stay and die, or walk away and take this thug's word that they will both live. It's not long before more seemingly unconnected and innocent people across London are offered a deal in exchange for their life. More blood is spilled, more families shattered and more people are left to suffer with the consequences of their decisions.

Sadie Nicholls has been found dead, brutally and strangely murdered, in her South East London flat. Her little boy is missing. DI Alex Finn and DC Mattie Paulsen know that, in the case of a missing child, it's the first 24 hours that count. They don't have many left to find out where Sadie's son might be and the identity of her killer. Why would anyone want a struggling single mother, loved by many, dead?

An ordinary day. An ordinary street. A gruesome delivery waiting on the doorstep that's going to set off an spine-chilling chain of events.

During a summer heatwave, teenagers are going missing. Junior officer Alex Finn takes the case and fears that the disappearances are linked. In a race against the clock to find and rescue the children alive, Finn and his team are only partially successful. Two of the children are saved, but they were too late for Oliver. And the killer got away. DI Alex Finn is still tormented by the cases of his youth - none more than so than the 2009 kidnappings. And it seems someone else has not forgotten either.
