Now re-married - to the woman he was having an affair with while still married to Alice - Ben's life is once again spiraling out of control, and he's become heavily indebted to an unscrupulous criminal who is baying for Ben's blood.

When Ben's estranged twin sister, a police detective, unexpectedly returns to his life, asking too many questions for comfort, it becomes clear that without action, Ben's life will soon reach a crisis point from which there will be no return.

In order to avoid falling further into the mire, Ben must examine the past if he is to survive the present - but just how much pressure can one man take before he breaks?

Fixated on her estranged sister’s death, a woman heads to the Spanish coast to conduct her own investigation—but will the truth bring her peace?

Ever since her sister, Anya, was murdered in Sotogrande, a playground for the rich, Natasha’s life has gone off the rails. After three months of poring over the details of what happened, Natasha travels to the scene of the crime where she hopes to unravel the truth—about her sister’s death and life. With no job, how did Anya end up in a multimillion-Euro apartment in one of the most exclusive areas on the continent?

The police have no suspect. Publicly, they claim the killing was likely gang-related. But their key person of interest, a local with links to organized crime, is also now dead. His fingerprints were found in Anya’s luxury apartment—but so too were the fingerprints of several others, all of whom could be suspects.

But how were these people linked to Anya? And which of them is responsible for her murder?
