WHAT THE DEVIL KNOWS – C.S. Harris (Released April 6th, 2021)

Book Description:

Sebastian St. Cyr thought a notorious serial killer had been brought to justice until a shocking series of gruesome new murders stuns the city in this thrilling historical mystery from the USA Today bestselling author of Who Speaks for the Damned.

It’s October 1814. The war with France is finally over and Europe’s diplomats are convening in Vienna for a conference that will put their world back together. With peace finally at hand, London suddenly finds itself in the grip of a series of heinous murders eerily similar to the Ratcliffe Highway murders of three years before.

In 1811, two entire families were viciously murdered in their homes. A suspect–a young seaman named John Williams–was arrested. But before he could be brought to trial, Williams hanged himself in his cell. The murders ceased, and London slowly began to breathe easier. But when the lead investigator, Sir Edwin Pym, is killed in the same brutal way three years later and others possibly connected to the original case meet violent ends, the city is paralyzed with terror once more.

Was the wrong man arrested for the murders? Bow Street magistrate Sir Henry Lovejoy turns to his friend Sebastian St. Cyr, Viscount Devlin, for assistance. Pym’s colleagues are convinced his manner of death is a coincidence, but Sebastian has his doubts. The more he looks into the three-year-old murders, the more certain he becomes that the hapless John Williams was not the real killer. Which begs the question–who was and why are they dead set on killing again? 

My Thoughts: 4/5 stars

This is the sixteenth, yes you read that correctly, entry in the Sebastian St. Cyr series and I’m impressed with how well the series has been continuing! At some point you would think it would feel overly repetitive but I’ve been thoroughly impressed with the ones I’ve read (started with thirteen). WHAT THE DEVIL KNOWS brings us another set of killings and a new mystery to be solved involving a potential copy cat or even worse, the real killer that was never caught.

Three years ago a series of gruesome murders occurred and a young man was arrested. Sentenced to prison, John Williams then hung himself, but the murders stopped so that means they must have had their man. Well, present day, the lead investigator into John Williams is found killed in the same horrible way as the original killings. Is this the work of a copycat? Sebastian St. Cyr is on the case and the more he digs into the case and present day killings, he quickly begins to realize that they may have had the wrong man and the real killer is now at large once more.

Not only do we get the great murder investigation but we get a nice dose of historical fiction as well. Harris always does such an incredible job setting the scene and bringing us to the early 1800’s London. If you’re looking for a new historical fiction/crime fiction series to start, I highly recommend picking up one of the Sebastian St. Cyr books. They can be read as standalone novels, so you can really start with whichever synopsis catches your eye!
