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....

More blood is spilled, more families shattered and more people are left to suffer with the consequences of their decisions.

During a summer heatwave, teenagers are going missing. Junior officer Alex Finn takes the case and fears that the disappearances are linked.

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.
