Secrets in the Shadows… Danger in the Light
Toronto, 1946. In the midst of a frigid January night, a desperate man bursts into the precinct, clutching a battered briefcase and claiming to hold proof of a Soviet spy ring entrenched in the city. Before detectives Mick McCathie and Mack MacNeely can piece together the cryptic documents, the informant vanishes—leaving behind a trail of coded messages, mysterious maps, and a list of names tied to key institutions.
As Mick and Mack dig deeper, they uncover chilling connections to Dominion Engineering, a reclusive physics professor, and an ominous project codenamed "Evergreen." Their pursuit takes them to the opulent King Edward Hotel, where a glamorous charity ball conceals shadows of conspiracy. With a Soviet defector seeking refuge and whispers of betrayal at the highest levels of Canadian law enforcement, the stakes rise to a fever pitch.
But danger has already caught up with them. Cornered in a darkened hotel kitchen by cold-eyed Russian agents, Mick and Mack must fight to survive—and to expose a plot that threatens not just Toronto but the balance of power in a rapidly changing world.
Will Mick and Mack uncover the truth before it’s too late? Or will they fall victim to a deadly game of espionage and deceit?
Shadows Over Toronto pulls readers into a gripping noir mystery filled with tension, danger, and intrigue.

The Vatican's Lost Daughter: The Enduring Mystery of Emanuela Orlandi - Part 1
In the heart of Rome, where secrets whisper from ancient stones, 15-year-old Emanuela Orlandi vanished into the night. A daughter of Vatican privilege, her disappearance on June 22, 1983, spiraled into an international enigma.
The Vanishing: Emanuela steps out from her music lesson, her last moments marked by a suspicious job offer and a conversation at a bus stop. Then, silence.
The Hunt: Pope John Paul II's plea for her return echoes through the world, but the truth is cloaked in darkness. Terrorists claim her abduction, demanding a killer's release, yet the narrative unravels, leaving a maze of motives—could it be organized crime, a serial killer, or a Vatican scandal too dark to unveil?
The Enigma: Decades later, the case remains a haunting melody, with each investigation ending in the same, frustrating silence. Calls from 'Pierluigi', 'Mario', and 'the American' weave a web of deceit. A chilling recording hints at torture, but the voice... is it Emanuela's?
The Cover-Up? With each year, the Vatican's silence grows louder. Was this disappearance a distraction from something far more sinister within the Holy See? As the Orlandi family battles for answers, the truth seems an ever-elusive specter, hidden perhaps in the Vatican's deepest vaults.
Dive into a story where faith meets conspiracy, where every lead is a dead end, and every silence a scream. Uncover the layers of intrigue in this chilling true crime saga that challenges the sanctity of one of the world's most sacred institutions.
Will the truth ever come to light, or will Emanuela Orlandi remain the Vatican's Lost Daughter?

Murder Before Midnight
On a snowy New Year’s Eve in 1945, Toronto’s elite gather in the grand ballroom of the Royal York Hotel, where the dazzling music of Mart Kenney and His Western Gentlemen fills the air. Beneath the glitter and celebration, trouble stirs when notorious fixer Jimmy Callahan drops dead, a champagne flute shattered at his side. Poisoned, it seems—but by whom?
Detective Mick McCathie and his partner, Mack MacNeely, are called to untangle the mystery before the clock strikes twelve. As the duo navigates the glittering crowd, they uncover secrets of smuggling, wartime profiteering, and a missing diamond necklace. Their investigation tightens around a host of suspects: a glamorous singer with a troubled past, a wealthy industrialist with too much to lose, and a small-time crook with everything to hide.
As the countdown to midnight begins, Mick and Mack race to stop a deadly scheme that could cost more lives. From the shimmering ballroom to the icy rooftop, where a final confrontation awaits, the detectives face a dangerous game of deception and betrayal.
Will they uncover the truth before the last note of “Auld Lang Syne” plays, or will the murderer escape into the night? One thing is certain: this New Year’s Eve, the party won’t end without a price.
Murder Before Midnight: A gripping noir mystery filled with suspense, danger, and two detectives who won’t stop until justice is served.
