Gregory Harris books in order

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...

Colin Pendragon's reputation as a brilliant detective is undisputed in Victorian London. But when murder strikes inside the closed ranks of Her Majesty's Guard, he must penetrate a wall of silence and secrecy to discover the dark truth...

After a captain in Her Majesty's Guard and his young wife are brutally murdered in their flat, master sleuth Colin Pendragon and his partner Ethan Pruitt are summoned to Buckingham Palace. Major Hampstead demands discretion at all costs to preserve the reputation of the Guard and insists Pendragon participate in a cover-up by misleading the press.

In response, Pendragon makes the bold claim that he will solve the case in no more than three days' time or he will oblige the major and compromise himself. Racing against the clock--and thwarted at every turn by their Scotland Yard nemesis, Inspector Varcoe--Pendragon and Pruitt begin to assemble the clues around the grisly homicide, probing into private lives and uncovering closely guarded secrets. 

As the minutes tick away, the pressure--and the danger--mounts as Pendragon's integrity is on the line and a cold-blooded killer remains on the streets. . .

Victorian London's private detective Colin Pendragon learns that the cost of wealth can indeed be dear as he investigates the grisly fate of a well-heeled financier. . .

When wealthy Edmond Connicle suddenly disappears, his distraught wife enlists the services of master sleuth Colin Pendragon and his loyal partner, Ethan Pruitt. Already on the case, however, is Scotland Yard's Inspector Varcoe. He suspects the Connicles' West African scullery maid of doing in her employer, especially when a badly burned body is discovered on the estate grounds with a sack of Voodoo festishes buried beneath it.

But all is not as it seems, and as more bodies are found, the pressure mounts on Varcoe, forcing him to forge an uneasy alliance with his nemesis, Pendragon. At the same time, Mrs. Connicle's fragile mental state appears increasingly more precarious. Could madness, not black magic, be at the root of these murders? To untangle the twisted truth, Pendragon and Pruitt must penetrate the hidden lives of the elite and expose the malevolent machinations of a ruthless killer. . .

Master sleuth Colin Pendragon and his trusted partner, Ethan Pruitt, leave their familiar cosmopolitan London for rural Sussex County, where the bucolic peace has been shattered by the murder of a monk…

At the request of his father, Pendragon and Pruitt travel to the town of Dalwich, where a gruesome crime has desecrated the hallowed halls of Whitmore Abbey. The abbott has been slaughtered in his cell with multiple stab wounds and his tongue cut out. Although Father Demetris, the local bishop's associate, has faith that the killer must be an outsider from the village, Pendragon considers no man above suspicion--including the brooding brothers of the order.

But before Pendragon and Pruitt can make much progress in their investigation, a second corpse is found--a barmaid who has been mutilated in the same way as the monk. Now they must determine if there is a connection between the butchered Benedictine and the victim from the village. Whether the killer comes from within the walls of Whitmore Abbey or without, it will be up to Pendragon and Pruitt to illuminate--and unravel--a deadly mystery before more lives are lost…

In Victorian London, there exists no greater investigative team than master sleuth Colin Pendragon and his loyal partner, Ethan Pruitt. But it will take all their powers of deduction to determine if a fatal fall was a result of misery or murder ...

Adelaide Endicott—elderly sister of Lord Thomas Endicott, a senior member of Parliament—has plummeted to her death from the third-floor window of her bedroom at Layton Manor. Did she take her own life—or was she pushed? Although Scotland Yard believes it is a clear case of suicide, Adelaide’s sister Eugenia is convinced otherwise ...

Intrigued by the spinster’s suspicions, Pendragon and Pruitt look into the victim’s troubled mental state while simultaneously exploring who might have had a motive to push Adelaide to her death. As they begin to uncover a family history involving scandalous secrets, abuse, and trauma, mounting evidence suggests that there is evil lurking behind the closed doors of Layton Manor, and that it is of utmost urgency to expose it before another tragedy occurs.

Of all the ghastly crimes in Victorian London, none are as infamous—or unsolvable—as those of Jack the Ripper... 

The murder scene is chillingly familiar. A young prostitute has been slaughtered in her flat on Framingham Street in the East End. It’s not the first time Scotland Yard has seen a murder like this. But with the help of Colin Pendragon and his loyal partner Ethan Pruitt, they hope it will be the last...

Word of the Ripper-esque crime has begun to spread across London, sparking a fresh wave of fear, dread, and panic. Two prostitutes have already been killed. But when a third victim is claimed, Colin and Ethan are forced to explore every possibility—from the opium dens of Whitechapel to the darkest corners of the London morgue. For Colin, the answer will prove to be as elusive—and deadly—as the Ripper himself...
