    Welcome to My World

    I’ve been telling stories for as long as I can remember. A surprising number of them have made it into print—fifteen novels so far, which still surprises me a little when I say it out loud. I live in the woods nears Stockton, New Jersey, a small borough on the Delaware River. The kind of place that inspires mysteries, thrillers and horror in the towns and countryside.

    My longest-running series is The Kyle Callahan Mysteries—character-driven, funny in places, dark in others, and rooted in lives you might never expect to be troubled by murder. I also write the Marshall James Thrillers series and the Maggie Dahl Mysteries, each with their own voice and world.

    More recently I’ve been working in horror and psychological thriller—territory I find endlessly compelling. And my forthcoming (September, 2026) Devil’s Wood is a supernatural thriller set in nearby Lambertville, drawing on modern small town life and ancient horror.

    Through Your Write Path, I offer workshops and coaching for writers at every stage—beginners who’ve never shown anyone their work, experienced writers who’ve hit a wall, people who want to tell the story of their own lives. “Every life is a story, and each of us is the storyteller.”

    My imprint Vivid Press publishes annotated editions of public domain classics—recent titles include Carmilla, The Willows, and Gaston Leroux’s The Mystery of the Yellow Room. Stories matter.

    Look around, you’ll find much more here, and thanks for stopping by. – Mark

    True Crime Tuesdays on the Fearsome Fiction Podcast: Axe Murders and Mirrors

    True Crime Tuesdays on Fearsome Fiction: Axe Murders and Mirrors

    On the night of June 9th, 1912, eight people went to sleep in a small farmhouse in Villisca, Iowa. Six of them were children. By morning, all eight were dead — killed with an axe as they slept, in a crime so deliberate the killer stopped to cover every mirror in the house before he left. More than a century later, despite two trials, a confessed minister, a state senator with a grudge, and a theory that reaches all the way to a serial killer riding the rails, nobody has ever been convicted.

    This week on True Crime Tuesdays, we walk through the Villisca ax murders — the victims, the suspects, and the eerie detail that still brings visitors to the restored murder house today, some of whom don’t make it until morning.
