The Case of the Missing Toys
Toronto, December 1945
It was supposed to be a simple holiday season—until a heartless thief made off with a shipment of toys destined for the children of Victoria Hospital. With Christmas just days away, the city’s cheer is under threat, and Toronto’s top detective duo, Mick McCathie and Mack MacNeely, are called in to save the day.
What starts as a case of stolen toys spirals into a whirlwind of chaos involving shady informants, frantic chases through Kensington Market, and a Santa Claus with a criminal past. From the twinkling lights of Eaton’s Christmas windows to the smoky haze of Rosie “Reds” DeLuca’s bar, Mick and Mack follow the trail of a bumbling thief with a surprising motive. Along the way, they’ll cross paths with colorful characters, dodgy leads, and plenty of snow-covered misadventures.
Will Toronto’s finest detectives crack the case and bring back the missing gifts in time to save Christmas? Or will the city’s children wake up to empty stockings on Christmas morning?
With humor, heart, and a sleighful of holiday twists, The Case of the Missing Toys is a festive mystery that will warm your heart—and keep you guessing—until the very last snowflake falls.

The Silent Shadows: The Suzanne Miller Mystery
In the quiet streets of London, Ontario, Suzanne Miller lived a life defined by devotion—her love for her three children, her modest home near the army barracks, and the steady rhythm of her days. But on September 15, 1974, a routine Sunday drive shattered the calm forever.
Suzanne vanished without a trace, leaving behind a family consumed by worry and a community gripped by fear. Days later, her blue Datsun was discovered abandoned, a silent witness offering no answers. And then, a month later, the unthinkable: Suzanne’s body was found in a remote wooded lot near the Thames River, her life stolen by a brutal act of violence.
The mystery only deepened. Who was the balding man at her visitation, reeking of alcohol and claiming to be “a friend”? What secrets did her spotless car conceal? And why, nearly five decades later, has justice remained elusive?
The Silent Shadows: The Suzanne Miller Mystery plunges into one of Ontario’s most chilling cold cases, weaving together heartbreaking details, elusive leads, and the relentless search for answers. With a $50,000 reward still on the table and a killer who may finally be ready to confess, the story of Suzanne Miller continues to haunt the city she called home.
