A case comes crashing into Detective Inspector Dan Rowntree's life, demanding his attention and driving him to desperation.

Detective Eva Roberts, however, is drawn in for reasons both personal and professional.

Rowntree's plea is simple: find his brother before time runs out. Roberts agrees to help, not out of choice, but out of obligation.

They're tied together by a complex web of friendship, debt, and loyalty - a bond that can prove both a strength and a weakness.

As they dig deeper, the narrative of Rowntree's case begins to unravel.

Witnesses falter under intense scrutiny.

Somebody is hell-bent on concealing the past.

Their search leads them into the heart of South London, where deceit and ruthlessness govern the rules of a treacherous underworld.

Infiltrating this dark world may be their only chance at uncovering the truth.

• To tread this perilous path, Roberts and her partner Bradley must cross into a world of violence and betrayal.

• Loyalty and trust hang precariously in the balance.

• The secrets they uncover threaten to shatter more than just the case that brought them here.

• Their partnership will be pushed to the limit - and beyond.

Surviving the dangers - and revealing the hidden truth - will require a monumental effort from Roberts and Bradley.

"Absolutely brilliant!" and a testament to a gripping narrative that refuses to release its grip.
