One night. Two cases. Three deadly secrets.

Dennis Canning has been murdered. Decades ago, he destroyed an entire family—has someone now taken revenge? DI Sheridan Holler believes so, but everyone has an alibi.

Then a brutal attack leaves a colleague fighting for her life in hospital. The investigation points to one suspect, but Sheridan can't prove it. Time is running out, and the evidence she needs is just out of reach.

Desperate and haunted by the ticking clock on both cases, Sheridan crosses a line she never thought she would. She turns to someone she shouldn't trust—someone who can help her get the proof she needs, no matter the cost to her conscience or even her career.

As the cases intertwine and dark secrets surface, Sheridan discovers that some alibis are too perfect—and some crimes are decades in the making. But when you break the rules, the consequences might destroy you.
