The Summoner

Book One

When a United States diplomat disappears in front of hundreds of onlookers while attending a religious ceremony in Zimbabwe, Diplomatic Security special agent Dominic Grey, product of a violent childhood and a worn passport, is assigned to investigate.

Aiding the investigation is Professor of Religious Phenomenology Viktor Radek, as well as Nya Mashumba, the local government liaison.

What Grey uncovers is a terrifying cult older than Western civilization, the harsh underbelly of a country in despair, a priest seemingly able to perform impossibilities, and the identity of the newest target.


The Egyptian

Book Two

At a mausoleum in Cairo’s most notorious cemetery, a mercenary receives a package containing a silver test tube suspended in hydraulic stasis.

An investigative reporter tracking rogue biomedical companies is terrified by the appearance of a mummified man outside her Manhattan apartment.

A Bulgarian scientist who dabbles in the occult makes a startling discovery in his underground laboratory.

These seemingly separate events collide when Dominic Grey and Viktor Radek, private investigators of cults, are hired by the CEO of an Egyptian biomedical firm to locate stolen research integral to the company’s new life extension product. However, after witnessing the slaughter of a team of scientists by the remnants of a dangerous cult thought long abandoned, Grey and Viktor turn from pursuers to pursued.

From the gleaming corridors of visionary laboratories to the cobblestone alleys of Eastern Europe to a lost oasis in the Sahara, Grey and Viktor must sift through science and myth to uncover the truth behind the Egyptian and his sinister biotech—before that truth kills them.

The Diabolist

Book Three

Globe-hopping detectives Dominic Grey and Professor Viktor Radek have a distinct specialty: they investigate matters that involve mysterious or unexplained phenomena. Crimes that other agencies can’t or won’t touch.

When a controversial religious leader is immolated in the Mission District of San Francisco, the local police chalk it up to a bizarre suicide. Yet witnesses claim a mysterious robed figure set fire to the priest. When a cult leader in Paris dies under similar circumstances, Interpol asks Grey and Viktor for help.

Convinced the culprit is a charismatic New Age prophet who has become an Internet sensation, Grey and Viktor undergo a perilous journey into the world of the occult as they try to penetrate the prophet’s inner circle. Along the way, they realize the prophet has ties to Viktor’s past, and that a far more sinister plan is afoot—a plan that, if successful, will shake the world to its core.

From the catacombs of Paris to London’s nefarious East End, from the haunted walls of York to a lost fortress in the Sicilian wilderness, Viktor and Grey’s latest case plunges them into a vortex of modern-day black magic, ancient heresies, and the most dangerous place of all: the cobwebbed corners of their own pasts.

The Shadow Cartel

Book Four

The sins of the past always return…

The General. A name whispered in hushed tones among the criminal underworld, from Miami to Buenos Aires. A name even the drug cartels fear.

Yet the General is a man without a face. There are no fingerprints on file, no known base of operations, not even a biographical sketch. He operates in the shadows, but somehow controls a vast criminal empire.

And he has never made a direct incursion onto U.S. soil—until now.

In Miami, disgraced DEA agent Fred Hernandez is called to investigate a bizarre crime scene, where the bodies of four drug dealers are sprawled around an iron cauldron. Even stranger is the mysterious ‘blue lady’ that a drug-addled witness claims killed the men.

Lana Valenciano, an ambitious CIA operative, informs Agent Hernandez that the murders might be connected to a legendary South American criminal known as the General. Lana claims the General has become a threat to national security—but has no idea how to find him.

The government’s best hope? Private investigators Dominic Grey and Viktor Radek, who might be the only people alive with the skills to unravel the General’s tangled web.

Thrown together on a covert manhunt, Grey and the two agents delve into the darkest reaches of international drug trafficking, only to unearth a sinister chapter in the history of the CIA that has spilled into the present—and put them in the crosshairs of an underworld puppeteer with a frightening reach.

The Resurrector

Book Five

Finalist for International Thriller Writers Award

A modern day Dr. Frankenstein, probing the secrets of life and death.

A secret society spawned by the greatest evil the world has ever known.

Two men racing against the clock to stop the spread of a horrific virus.

On three different continents, a mysterious illness has baffled scientists and incited worldwide panic. When a tattoo steeped in Aryan mysticism is found on one of the victims, a South African boy who walked into his township a month after his own funeral, Interpol turns to Professor Viktor Radek and Dominic Grey for help.

After racing from Atlanta to Rekyjavik to Cape Town, Grey and Viktor come to believe the deadly virus is connected to a resurgence of a legendary arm of the Nazi party. A global organization whose leader might be a notorious brain surgeon rumored to have performed illicit tests during Apartheid, and who might be continuing his experiments from a sun-drenched manor in the Western Cape.

As the victims of the virus mount and the chance for a cure fades, the world’s only hope to prevent a catastrophe beyond imagining rests in the hands of a broken warrior and a relentless professor, facing the darkest of forces.

The Reaper’s Game


Is it murder from beyond the grave . . . or the final ruse of a twisted serial killer?

Three years ago, a deranged murderer dubbed the Halloween Killer butchered half a dozen people in New Orleans. He was caught and sentenced to die. Just before his execution, the Halloween Killer vowed to take revenge on the district attorney who put him behind bars.

Less than a week after the lethal injection, Sebastian Gichaud, a wealthy playboy grieving over the death of his mother, throws on a black cloak and hacks the prosecutor to death with a giant scythe.

Not only did Sebastian appear to be fulfilling the serial killer’s last wish—he claimed that he was the Halloween Killer.

Now, as the anniversary of the grisly murder approaches, Sebastian is facing trial. No one will touch the case. In a desperate attempt to save his son, Sebastian’s father hires Viktor Radek, professor of religious phenomenology, to investigate.

If Sebastian is guilty, Viktor wonders, then why are he and his associate Dominic Grey being warned off the case? And why did the Halloween Killer visit a series of reincarnation experts before his death?

None of Professor Radek’s doubts might matter, because he and Grey face the impossible task of convincing an Orleans Parish jury that Sebastian Gichaud is either a prisoner in his own mind—or possessed by the spirit of the Halloween Killer.

The Family

Book Six

Will the source of an ancient mystery finally be revealed?

On a cobblestone street in Prague, a murder victim is found with two puncture wounds resembling bite marks on her wrist. The cause of death is ruled as exsanguination—severe blood loss.

Worried the chilling crime will ignite a media firestorm, the Czech police call on Professor Viktor Radek, renowned professor of phenomenology. Like the authorities, Viktor arrives at the only rational conclusion: the murderer is mimicking a vampire.

Yet during the investigation, Viktor uncovers a suspect with a connection to the Order of the Dragon, an ancient organization dedicated to keeping the Ottomans out of Europe. An organization whose membership once included Vlad the Impaler, long thought to be the historical basis for Bram Stoker’s infamous count.

In a dual-timeline narrative that keeps the reader guessing at every turn, Grey and Viktor follow a trail of clues across Central and Eastern Europe that draw them deeper and deeper into a mystery involving the origins of the vampire mythology, as well as a modern-day crime family with secrets they will go to great lengths to keep hidden. Secrets that might be more terrifying than Viktor and Grey could ever have imagined—and which draw them ever closer to a seemingly impossible realization.
