Agent of the Crown

Adult - Action -  Thriller

Agent of the Crown is my adult action-thriller series, following Piety as she hunts ancient evils through our green and pleasant land.

Piety is an agent, one of the Queen’s elect, charged to defend the realm against impossible threats, and carrying the full power of the throne with her.

There is nowhere she cannot go. Nowhere where evil can hide.

For more than a thousand years, agents have guarded Britain against the infernal. The 1960s might be terribly modern, but the threat has never changed. Even in the midst of the cold war, older foes still lurk, needing older weapons to stop.

Fire and steel. Blood and duty.

Follow Piety as she roots out corruption, slays dragons and stands against the darkness.

Piety

Agent of the Crown

Book 1

Adult - Action -  Thriller

PietyMed.png

A distant island with occult secrets.

An old flame serving a dangerous master.

A plot to start a nuclear war.

In 1961, with Kennedy in the White House and the Cold War in full swing, William Fitzwilliam is sent to the remote Shetland Islands to chase down dubious reports of arcane agriculture. All in a day’s work for a junior operative in Britain’s most secret service.

Fitz expects a couple of provincial warlocks dancing under the northern lights. Instead, he lands in the middle of bloody firefights between cultists and his fellow agents, with terrifying magic being wielded by both sides.

And waiting for him in the gunsmoke is Piety. 

The girl who broke his heart, when she left to serve under Magnus: the infamous, ruthless senior agent leading this off-the-books investigation. 

Every answer Piety gives pulls Fitz deeper into the conspiracy that brought her and Magnus to Shetland, and the private war raging across the islands. 

The only thing Fitz knows for sure is that something far more sinister than occult wheat has been growing, and unless he uncovers the truth, the Cold War may be about to turn hot.

Piety's Fury

Agent of the Crown

Book 2

Adult - Action -  Thriller

FuryCoverMed.png

A missing girl with a deadly gift.

A family with a dark secret.

A threat that brings Piety home. 

It’s December, 1961. Newly promoted, and sent on her first independent assignment, Piety is ordered back to rural Antrim, to the orphanage where she grew up. 

A twelve-year-old girl has vanished from the convent. Her name is Lissy Vaughn, and she is no ordinary child: born with magic in her blood and a voice that can kill. But Piety soon discovers that someone else has been using older, darker magic to control her.

Ancient stones taken from the grave of a murdered king are found hidden in Lissy’s room, exerting malign influence while she sleeps. As Piety digs deeper, she uncovers a pattern stretching back decades. Girls who were taken, but never truly vanished. Girls who joined a new family. 

Finding Lissy is only the beginning.

Because whatever has hunted these girls for generations has now followed Piety back to her home. Suddenly, the mission is no longer just one missing girl. It’s ending the terror that’s coming for her family.

Piety's Legacy

Agent of the Crown

Book 3

Adult - Action -  Thriller

LegacyCoverMed.png

A mentor with a shadowy past.

An underworld gang wielding the power of a fallen empire.

A deadly struggle for an apocalyptic treasure.

It’s early 1962, and promotion is not sitting well on Piety. Beset by paperwork, she has taken to hunting down magical misdemeanours just to keep her edge.

 

When she follows an insignificant artefact dealer into the disused tunnels beneath London, she expects a routine arrest. Instead, she finds him brokering impossible relics: an enchanted stethoscope, and a flashbulb that can see through bank vaults.

 

The hand-off turns into a midnight gun battle under Blackfriars bridge, leaving the seller shot in the back, one henchman dead, and a buyer with glowing cat’s eyes vanishing into the Thames.

 

Pursuing the investigation leads Piety through London’s occult underworld, and towards a gang reputed for savagery building a criminal empire with plundered Aztec secrets. But they aren’t interested in banks or gold.

 

They are hunting a safe, buried somewhere under the city. A safe hidden by Piety’s former mentor, presently on trial for treason. A safe said to contain the essence of a moon goddess, and pursued by one of Piety’s fellow agents for more than a decade.

 

Enemies are swirling. Even friends are not above suspicion.

 

Whatever is truly in the safe, it contains Piety’s inheritance. Hers by right, but only if she can take it.

Piety's Depths

Agent of the Crown

Book 4

Adult - Action -  Thriller

DepthMed.png

A coal town with too many accidents.

A fist-sized diamond with an unexpected owner.

An impossible threat, born from the darkness.

It’s spring 1962, and Piety is off the grid, letting the dust settle after she earned the wrath of a fellow agent by keeping a powerful artefact out of their hands. London is far behind, and Piety is in south Wales, hunting for any problem serious enough to justify ignoring orders from headquarters.

 

Industrial unrest has been spreading through the Aber Valley, with coal miners out on strike. The unions claim it is safety concerns and miserly owners. But behind the picket-line slogans, dark rumours are swirling amongst the miners.

 

Supposedly, the colliery at Senghenydd has been reopened, a mine that was sealed fifty years ago after a massive explosion killed hundreds of miners. The old owners are long bankrupt. The lifts have long been removed, and the shaft filled with concrete. But someone has been down there, bringing something much more valuable than coal back with them.

 

Gold has been mined in Wales for centuries. But hundred-carat diamonds can’t have been created by natural means.

 

Something is lurking in the old mine. Something that survived the explosion that took four hundred lives. Something ancient and impossible, with breath that can fuse coal into diamond.

 

Piety must track down the thieves, who went to plunder the miners’ graves, follow them back to the mine to find whatever was sealed in the darkness a thousand feet below Senghenydd.

And confront what lies beneath.
