M.A. Mollenkopf

Retired U.S. Army Warrant Officer and cybersecurity specialist, I write stories where logic tangles with technology and motive wins or loses the day. If you like Sherlock-style deduction welded to near-future tech (and a dash of spacefaring wonder), you’re in the right place.

I always wanted to be an astronaut and became an instant, lifelong SF fan after discovering Robert Heinlein’s Space Cadet.

The Fantasy Casino Murders has launched!

November 23, 2025

Jack Stewart is back in a brand-new tech-noir mystery set in the glittering Fantasy Casino on the edge of Wellspoint, Ohio. As he hunts a killer manipulating the casino’s data driven systems, Jack is forced to confront the darkness he’s been holding at bay.

Jack Stewart began as a man seeking justice in a world of shadows. Yet, the more I wrote, the more he revealed a darker truth, a stark departure from the man he once was. He wrestles with a darkness within, a volatile nature he struggles to keep in check. Jack’s struggle echoes the legend of Jekyll and Hyde, a constant battle to contain the violent force that threatens to erupt, a force that could harm the very people he’s sworn to protect.

This launch marks the next chapter in the Jack Stewart Mysteries—a gritty story of a man fighting the monster within, bound to a brilliant young computer forensics analyst, Sarah, whose insight may be the only thing standing between Jack and a complete descent into darkness.
