American Quartet (Fiona Fitzgerald Mysteries, #1)

Fiona Fitzgerald Mystery #1: Detective Fiona Fitzgerald is an unlikely force for justice in Washington D.C's predominantly male police force. As a prominent senator's daughter and top investigator in the homicide division of the Metropolitan Police Department, Fiona maneuvers between two vastly different worlds, moving quickly from opulent State galas to gritty crime scenes. Born into the elite social circles of the nation's capital, and with privileged access to what lurks behind the pristine façade of the political establishment, Fiona is determined to expose the chicanery buried under prim rose bushes and concealed within the highest echelons of the American political aristocracy.
When a string of inexplicable murders rocks the hallowed streets of central D.C., Detective Fitzgerald finds herself charging through the shadows of a mysterious conspiracy. Fiona's reputation and career blunder, however, through an investigation with no leads. At the brink of her professional demise, an encounter with the eccentric yet charismatic Thaddeus Remington III at his museum-like mansion sends Fiona fluttering through a whirlwind of clues and revelations. Where once the desperate detective rummaged through traceless footsteps of a triple murderer, the key to solving her case is now whispered to her from the bloodstained graves of fallen Presidents.
Fiona stands ready with her unlikely yet determined partner Jefferson at her side. Her finger firmly on the trigger as an assassination plot, decades in the making, is about to change history.
