‘Viola’ was his Nonna’s maiden name—an homage to his Italian roots. Toni’s mother was born in a small village near Cassino, in southern Italy. The story she told of being hidden with her siblings inside wine barrels in an old pigsty during the German occupation of Italy, was the inspiration behind the original draft of The Cause Of All Fear.

Meroni - The Rome Trilogy is a character-driven crime thriller series featuring Detective Luca Meroni: a failed footballer and disgraced undercover cop. Following a botched assignment in Bari, a series of brutal investigations in the Eternal City test Meroni’s loyalty, resilience, and fractured grip on reality. A gripping series for readers who crave edgy thrillers and relish the dark pulse of international crime noir.
