Robertson, Imogen

For readers of historical fiction looking for a complex story, this is a sure bet and most likely the next big hit of any book discussion group.

Dramatic intrigue and painstaking detail combine smoothly in this robust historical thriller. While this is the fourth series entry (after the CWA Ellis Peters Historical Award nominee Island of Bones), Robertson does a particularly good job of filling in the backstory for new readers. Sure to be a treat for Anne Perry fans; try also with forensic investigation readers who like an ensemble cast.

The author has done her research (with two pages of historical notes as proof), and the authentic details and dialog transport readers back to 1781 London. However, the many references to the previous book make it essential that new readers start with that one. Fans of such historical mystery authors as Anne Perry and Charles Finch will delight in this new series.

Robertson's series debut offers an intriguing premise, but the story is marred somewhat by overwrought prose and villains who all tend to verge on caricature. For fans of historical thrillers and libraries with a healthy amount of wiggle room in their budgets.
