But when he stumbles across one of the Seven of Spades’s horrifying crime scenes, he can’t let go, despite Levi’s warnings to stay away. The Seven of Spades is ruthless and always two moves ahead. Worst of all, they’ve taken a dangerously personal interest in Levi and Dominic. Forced to trust each other, the two men race to discover the killer’s identity, revealing hidden truths along the way and sparking a bond neither man expected. But that may not be enough to protect them.

Weirdly, people don’t react overly well when you’re caught standing over the dead body of a murderer who’d walked free. It’s not that I thought my fellow homicide detective would rejoice when he saw what I’d done, but is a pat on the back too much to ask for? Maybe a gold star at the very least? The problem is that the person who caught me is Gabriel, the only person I care for and adore… and he’s prepared to look the other way if I leave homicide and promise to never kill again.
