In Anne Cleeland's engaging and original new mystery series, two of Scotland Yard's most gifted detectives navigate the darkest corners of London to solve a murder that will blur every line between right and wrong. . .

Despite their investigative prowess, Chief Inspector Michael Sinclair, Lord Acton, and rookie detective Kathleen Doyle stir more than a few feathers at CID Headquarters when their relationship comes to light. But office politics quickly become trivial when a rash of underworld murders shatters London's normally austere façade. With a growing list of successfully solved cases to her name, the ever-dauntless Doyle shakes off the gossip and sets out to investigate the escalating turf war.

As the body count climbs, Doyle uncovers a seedy world where fractious members of the Russian mafia and an Irish terrorist group are fighting for control of a lucrative underground business. But their crooked deals and volleying acts of revenge are almost too much for Scotland Yard to keep up with, and when Doyle notices that Acton seems unusually troubled by the crimes, she begins to wonder what sparked the conflict in the first place.

Perhaps there's nothing more to the murders than under-the-table business dealings gone awry. Or perhaps a single act of vigilante justice fanned the flames that ignited a vicious turf war. As Doyle and Acton fight not to become the next victims, they'll find that the truth may be best left unspoken, and retribution may be best left to fate. . .
