The Unsolved Swing: The Mysterious Death of J. Douglas Edgar
On the eve of golf’s golden age, J. Douglas Edgar was a legend in the making—a daring Englishman whose revolutionary swing conquered Canada’s greens and captivated the world. But on a sultry Atlanta night in 1921, his brilliance bled out under a dim streetlamp, a single, surgical wound severing his femoral artery. Was it a jealous lover’s blade? A gambler’s desperate payback? Or a hit-and-run shrouded in lies? Found dying in a pool of his own blood, Edgar took his secrets to the grave, leaving behind a puzzle no detective could solve. From the roar of the Canadian Open to the silence of an unsolved murder, this is the gripping tale of a champion whose final shot landed in shadows. Step onto the fairway of history—where every clue is a hazard, and the truth remains out of bounds.
Because every case deserves answers—and every victim deserves justice.

The Man from Nowhere: A Mick & Mack Mystery

The Man from Nowhere
Inspired by the real-life mystery of the Somerton Man: Soon to be featured on World True Crime Thursdays
A Mick & Mack Mystery: He washed up in Toronto Harbour with no name, no past, and a cipher no one could read.
No wounds. No identification. No explanation.
Just a well-dressed corpse, polished shoes… and a strange slip of paper tucked into his coat pocket. When Detectives Mick McCathie and Mack MacNeely are called to the scene, they expect a routine investigation. Instead, they find themselves unraveling a trail of coded messages, missing ships, and Cold War shadows hiding in plain sight.
As more bodies appear and clues point to a ghost network of couriers and double agents, the case begins to echo a chilling true crime from halfway across the world — the real-life Somerton Man mystery. But this time, the dead man’s message isn’t lost. It’s just waiting to be understood.With help from the enigmatic Eve Whitmore, Mick and Mack must decode the truth before a deadly secret slips out of Toronto… and into the wrong hands.
Part noir mystery, part spy thriller, The Man from Nowhere blends historical intrigue and classic detective banter in a case where even the dead have something to say — if you know how to listen.

Shadows of Violence: The Yorkshire Ripper’s Deadly Rehearsal (Part 2 of 5)
The predator stalks closer…
In the summer of 1975, northern England’s quiet corners became a testing ground for terror. Peter Sutcliffe—the man who would become the Yorkshire Ripper—was no longer a petty thief with a grudge. He was a shadow with a hammer, a blade, and a hunger growing sharper with every strike. Ontario Cold Cases - Canada’s True Crime Podcast plunges into Part 2 of its gripping five-part series, "Shadows of Violence: The Yorkshire Ripper’s Deadly Rehearsal," peeling back the blood-soaked prelude to his murderous spree.
From a crude sock-and-stone assault in Bradford’s red-light district in 1969, Sutcliffe’s rage erupted into a brutal rehearsal across West Yorkshire. Anna Rogulskyj’s skull cracked in Keighley’s alleys. Olive Smelt’s life shattered on Halifax’s dark streets. Tracy Browne, just 14, faced five savage hammer blows in Silsden’s lonely fields. Marcella Claxton crawled from Leeds’ bushes, her survival a haunting echo of his evolving cruelty. Four women, four near-deaths—each a chilling step as Sutcliffe honed his craft, inching toward the lethal plunge that would claim Wilma McCann and unleash a nightmare.
What twisted a shy loner into a predator who turned quiet lanes into killing grounds? How did tools of trade become instruments of terror? This isn’t just a tale of survival—it’s the making of a monster, strike by horrifying strike. Part 2 builds the tension, but the series spirals deeper: Part 3 unveils the murders, Parts 4 and 5 the manhunt and his end.
Subscribe now to Ontario Cold Cases—available wherever you get your podcasts—and brace yourself for a descent into darkness that’s only begun. The shadows are closing in, and the Ripper’s rehearsal is over. Are you ready for what’s next?

The Murder of Julia Wallace: An Impossible Mystery

The Murder of Julia Wallace: An Impossible Mystery
From the creators of Ontario Cold Cases – Canada’s True Crime Podcast
A locked room. A vanished killer. A crime so baffling it defies reason.
Liverpool, 1931. In a modest red-brick row house on Wolverton Street, Julia Wallace is found bludgeoned to death—her body crumpled in the parlor, a raincoat soaked in blood beneath her. Hours earlier, her husband, William Wallace, received a peculiar phone message summoning him across the city to a meeting with a man who didn’t exist… at an address that couldn’t be found.
What followed stunned the nation and confounded experts for nearly a century.
Was the mild-mannered insurance man a diabolical killer who staged the perfect alibi? Or the victim of a malevolent trap, framed by someone who knew his every move? With no murder weapon, no eyewitnesses, and a crime scene soaked in contradiction, the case became a real-life riddle that inspired mystery legends like Raymond Chandler and Dorothy L. Sayers to declare it “the impossible murder”—a crime with only two solutions, both equally unbelievable.
In this immersive true crime narrative, we delve deep into the timeline, the characters, the theories, and the chilling forensic gaps. From the shadowy figure known only as R.M. Qualtrough to the long-whispered secrets of a disgraced former colleague, we lay out the evidence and invite you to become the detective.
Nearly a century later, the question still burns: Who killed Julia Wallace?
Was it Wallace? Parry? Or someone else entirely?
Step into one of history’s most confounding cold cases—and decide for yourself.
Because every case deserves answers—and every victim deserves justice.

I Witness
Six witnesses. One robbery. A thousand contradictions.
A Mick & Mack Mystery
“Everyone’s a hero. Until the facts walk in.”
When a mid-morning bank job shakes up downtown Toronto, Detectives Mick McCathie and Mack MacNeely are sent to investigate what should be a straightforward case.
But something doesn’t sit right.
The bank manager insists he bravely negotiated with the thief.
One teller says she saved the day with a letter opener.
Another claims he nearly tackled the man himself.
Even the customers have wild tales — of chases, threats, and split-second heroics.
Everyone saw everything.
And yet… nothing adds up.
As Mick and Mack dig through the tangled web of timelines, tall tales, and self-serving statements, they begin to suspect that the real story isn’t what was said — it’s what was left out.
With sharp wit, fast banter, and a case full of colourful characters, I Witness is a classic Mick & Mack mystery where truth plays hide-and-seek… and not every hero is telling the truth.
