When the Wolves Are Silent

Sebastian St. Cyr Mysteries, Book 21

By: C. S. Harris

A brutal string of ritualistic killings terrorizes a city already shaken by economic and political turmoil in this chilling new historical mystery from C. S. Harris, USA Today bestselling author of Who Will Remember.

London, 1816: When a notorious young aristocrat is burned alive on a windswept hill popular with neo-Druids, former cavalry officer Sebastian St. Cyr, Viscount Devlin, finds himself plunged into a murder investigation shadowed by tales of ancient human sacrifices and long-buried secrets.

The victim, Marcus Toole, was the only son and heir of a prominent nobleman. His closest friend—Sebastian’s own nephew, Bayard—claims to have passed out drunk before the attack and remembers nothing. But when Sebastian and his brilliant wife, Hero, delve deeper into the sordid activities of Bayard and his friends, they come to realize that Bayard may not be as innocent as he pretends. Following a tangled trail that leads from a disaffected former soldier-turned-highwayman to a beautiful, courageous journalist and a Jamaican-born fencing master with ties to a radical political movement, Sebastian begins to suspect that Bayard and his friends are being targeted in revenge, by victims who believe they have no other recourse.

Then two more of Bayard’s friends are killed, their murders staged to echo the ritual sacrifices of the ancient Celts. With the palace shaken by the fear of riots and one horrifying death following another, Sebastian must race to stop a ruthless plot that threatens the lives of innocents and could rip his troubled nation apart.

Excellent

This is by far my favorite series and this new novel did not disappoint. I tried to drag it out because I just didn’t want it to end lol. I love how Tom Kiteley narrated and though I love Davina Porter and Jenny Sterlin I think Tom gave Sebastian the perfect voice. I can’t wait for book 22!

Excellent, narration, and historical relevance to modern US politics!!

Excellent, narration, and historical relevance to modern US politics!! I did not dislike anything, just trying to fill in the 15 Word minimum here!

Love the intricate story

This is another good book in the Sebastian series. This one is more about the state of affairs in London at the time of the murders and less about his family members.

Best in the series

This is a wonderful series and just keeps getting better and better! All the glory and horror of the regency come to life.

characters and excellent narrator

I love this series. I have really enjoyed the narrator. I look forward to (hopefully) many more books
