First-year detective Kathleen Doyle is a plucky Irish redhead of humble origins and modest means. Chief Inspector Michael Acton is her antithesis: a British lord turned cop. He's tall, handsome, and enigmatic--to a fault. He also has a knack for solving London's most high-profile crimes. Acton selects Doyle out of the newbie squad to partner with him on a series of investigations because she always knows when someone is lying--a trait that comes in handy when interviewing suspects and witnesses. Acton and Doyle are sent to investigate the murder of a trainer at a racetrack, and soon new killings related to the first start unfolding, dragging the two investigators into ever more perilous situations. But the real danger is the unlikely attachment that develops between the ultrareserved, aristocratic chief inspector and his spirited, working-class sidekick...a relationship that will raise plenty of eyebrows--and hackles--among their colleagues at the Yard.
