Set against the fog-shrouded backdrop of turn-of-the-century London, Gregory Harris's new historical mystery series introduces tenacious sleuth Colin Pendragon, and a case that illuminates the darkness lurking in the heart of one of England's most noble families.

When a carriage bearing the Arnifour family crest--a vulture devouring a slaughtered lamb--arrives at the Kensington home of Colin Pendragon, it is an ominous beginning to a perplexing new case. Lady Arnifour's husband has been beaten to death and her niece, Elsbeth, left in a coma. Is the motive passion, revenge, or something even more sinister? Police suspicions have fallen on the groundskeeper and his son, yet the Earl's widow is convinced of their innocence.

Even as Colin and his partner Ethan Pruitt delve into the muddy history of the Arnifour family, a young street urchin begs their help in finding his missing sister. Ethan, regrettably familiar with London's underbelly, urges caution, yet Colin's interest is piqued. And in a search that wends from the squalid opium dens of the East End to the salons of Embassy Row, the truth about these seemingly disparate cases will prove disquieting, dangerous, and profoundly unexpected. . .
