Uneasy Lies the Crown

In Uneasy Lies the Crown, the thrilling new mystery in Tasha Alexander's bestselling series, Lady Emily and her husband Colin must stop a serial killer whose sights may be set on the new king, Edward VII.
On her deathbed, Queen Victoria asks to speak privately with trusted agent of the Crown, Colin Hargreaves, and slips him a letter with one last command: Une sanz pluis. Sapere aude. "One and no more. Dare to know."
The year is 1901 and the death of Britain's longest-reigning monarch has sent the entire British Empire into mourning. But for Lady Emily and her dashing husband, Colin, the grieving is cut short as another death takes center stage. A body has been found in the Tower of London, posed to look like the murdered medieval king Henry VI. When a second dead man turns up in London's exclusive Berkeley Square, his mutilated remains staged to evoke the violent demise of Edward II, it becomes evident that the mastermind behind the crimes plans to strike again.
The race to find the killer takes Emily deep into the capital's underbelly, teeming with secret gangs, street children, and sleazy brothels—but the clues aren't adding up. Even more puzzling are the anonymous letters Colin has been receiving since Victoria's death, seeming to threaten her successor, Edward VII. With the killer leaving a trail of dead kings in his wake, will Edward be the next victim?
