From Jerusalem to Rennes-le-ChĂąteau, France, and from Rome to Buenos Aires, Father Michael Dominic and his friends take on a new adventure as they discover clues in old Nazi diaries that lead them to the most sacred artifact imaginable: the legendary Veil of Veronica, the cloth on which Christ cleansed his face on the road to Crucifixion, and which imparted his holy visage, showing what many believe to be the face of the Son of God.

Michael and Hana must track down clues in the form of three fragments of a mystifying puzzle in order to find the veil.

A Vatican Secret Archive Thriller – Book 1

During the Vatican’s papal conclave of 1740, violinist Antonio Vivaldi is given a devastating secret by his dying mentor, Cardinal Pietro Ottoboni, the man favored to be elected Pope before he was poisoned. Fearful of the Italian Camorra, Vivaldi hides the secret in a special cipher in his music—a cipher revealing a breathtaking centuries-long operation of art theft from the Vatican Museum and forgery of its priceless paintings.

Almost three hundred years later, the encoded music is discovered by Father Michael Dominic, Prefect of the Vatican Secret Archive, who tries decoding the cipher with the help of journalist Hana Sinclair and her former teacher, music cryptologist Dr. Livia Gallo. Dominic, Hana, and their Swiss Guard companions Karl Dengler and Lukas Bischoff, meet up in the enchanted city of Venice during Carnivale celebrations to further investigate Vivaldi’s coded music with the help of the maestro’s descendant, Contessa Donatella Vivaldi—whose palazzo on the Grand Canal holds many secrets of its own.

The notorious Italian Mafia organization known as the Camorra tries everything in its power to stop Dominic and his friends from digging deeper into their secret forgery operation. But now Dominic and his team are joined by former French commando Marco Picard, whose tactics are a stubborn match for the brutal ways of the Camorra.

A Vatican Secret Archive Thriller – Book 2

In 1982, Roberto Calvi, known as “God’s Banker,” was discovered hanging under London’s Blackfriars Bridge. What wasn’t found was the briefcase he was known to have had with him the night before, reportedly stuffed with explosive documents blackmailing some of the most powerful people in Italy, and perhaps more.

When the briefcase mysteriously reappears in the Vatican Archives, Father Michael Dominic and his team—Hana, Marco, Karl, Lukas, the feisty Pauline nun Sister Teri, and Dominic’s new assistant, Ian—are up against two powerful and enigmatic organizations, Opus Deus and the secret, outlawed Masonic Lodge P2, who savagely fight for control of the briefcase and its secrets. Their goal? To carry out one of the most dangerous conspiracies the Church has ever faced—all happening during an unexpected conclave to elect a new pope.

From Rome, Italy, to Geneva, Switzerland, join Dominic and friends as they fend off plotters, kidnappers, and blackmailers who have threaded their way into Vatican politics for decades, in a conspiracy known as The Opus Dictum.

The Petrus Prophecy

A Vatican Secret Archive Thriller – Book 3

Father Jonah Barlow is dead. The respected Jesuit scholar of apocalyptic studies might have died from a fall in his apartment . . . or was he pushed? All that is known for sure is that the provocative manuscript he was working on—a book that promised to reveal the upcoming fulfillment of ancient and recent prophecies, including the ghastly and shocking Third Secret of Fátima—is missing.

Two female detectives—one from Chicago, the other from Rome—take on the investigation as a possible homicide, turning to Vatican archivist Father Michael Dominic for his help, since Barlow sent the young priest the only other copy of the manuscript.

Meanwhile, a sinister ancient order known as the Knights of the Apocalypse seem to be using the predictions of the manuscript to create fear and chaos as the prophecies appear to be coming fulfilled. Is the end of the world imminent?

From Chicago to Jerusalem to Scotland, from Rome to the ancient island nation of Malta, join Father Dominic, journalist Hana Sinclair, their trusted team of Swiss Guards, a French commando, and the two detectives as they solve the bewildering puzzles of the Petrus Prophecy.

A Vatican Secret Archive Thriller – Book 4

A 700-year-old body is discovered in a hidden crypt buried deep beneath the burnt embers of Notre-Dame Cathedral in Paris during reconstruction after its disastrous fire. Presumed to be that of a bishop from the fourteenth century, two parchment scrolls had been secretly sewn into the man’s preserved garments—documents that could spell a royal upheaval for modern-day France.

While the country is in great political turmoil—with rival factions laying claim not only to the presidency, but to the republic’s royal heritage—the French government calls on the Vatican’s own Father Michael Dominic to extract and learn what secrets the parchments may hold. But when they lead him to the tomb of Pope Clement V, the priest discovers yet another set of shocking documents with hints of a vast treasure the pope had buried before he died in 1314. When a prominent figure seizes the seat of government by force, it’s now up to Michael, Hana, and Marco—along with their trusted Swiss Guards—to act.

A Vatican Secret Archive Thriller – Book 5

In an epic struggle of faith, knowledge and power, the discovery of a mysterious silver scroll in the Judean Desert pits rival factions against one another in a thrilling race to uncover the secrets it holds.

Two young Israeli boys discover an ancient red clay jar in a hidden cave tucked away in the Judean Desert near Qumran. Inside the jar are several scrolls written by the Essenes two thousand years earlier, before the Great Jewish Revolt, including one legendary scroll engraved on silver that speaks of what may be the great Lost Treasures of Solomon buried around Jerusalem—consistent with the predictions of the fabled Copper Scroll discovered in 1947 near the Dead Sea. But one of the overlooked parchments turns out to be far more pivotal to Christianity than anything ever before discovered—a startling manuscript written by St. Paul himself that could rewrite religious history.

Father Michael Dominic and his friends are called to Jerusalem to inspect the silver scroll, but others are trying to get to the precious manuscripts first—members of a little known sect called the Mithraists, the chief rival to Christianity up to the fourth century . . . a wealthy Texas televangelist . . . an Egyptian antiquities broker . . . Israeli Mossad agents . . . and a cast of rogues each out for themselves.

Follow the adventures of Father Dominic and his loyal team from Rome to the Holy Land—through the colorful bazaars of Cairo to the ancient holy sites of Jerusalem and Jordan—in this engaging, historical international thriller.

Non-Fiction Works

Based on stunning new details discovered in the personal journals and archives of former Kansas Bureau of Investigation Director Harold R. Nye—and corroborated by letters written by Richard Hickock, one of the killers on Death Row—And Every Word Is True lays out a fresh, meticulously researched perspective on the 1959 Kansas Clutter family murder case made famous by Truman Capote in his bestselling masterwork In Cold Blood.

In Cold Blood by Truman Capote

And if you have yet to read In Cold Blood, I highly recommend it as a companion to And Every Word Is True:

On November 15, 1959, in the small town of Holcomb, Kansas, four members of the Clutter family were savagely murdered by blasts from a shotgun held a few inches from their faces. There was no apparent motive for the crime, and there were almost no clues.

In one of the first non-fiction novels ever written, Truman Capote reconstructs the murder and the investigation that led to the capture, trial, and execution of the killers, generating both mesmerizing suspense and astonishing empathy. In Cold Blood is a work that transcends its moment, yielding poignant insights into the nature of American violence.
