Synopsis/Details

After a horrific murder inside a church confessional, veteran detective Callahan is drawn into a case that defies logic and evidence. The victim appears to have been attacked mid-confession—by something that was never seen entering or leaving.

As similar killings emerge, each more disturbing than the last, Callahan crosses paths with Elena Cruz, a sharp, relentless journalist who believes the murders are connected by more than coincidence. Together, they uncover a terrifying pattern: each victim is forced to confess a deeply buried truth moments before their death.

What begins as an investigation turns into a descent into something far more sinister—a presence that doesn’t hunt randomly, but listens… waiting for guilt, lies, and hidden sins to surface.

As the phenomenon spreads beyond a single location, Callahan is forced to confront his own past, realizing that the only way to stop the entity may be to give it exactly what it wants: the truth.

But some truths don’t set you free.

Some get you killed.

My newest novel and screenplay, ALL IS NOT CALM, is a Christmas action thriller with a simple commercial hook: “Die Hard on a luxury cruise ship.” On Christmas Eve, a former Coast Guard commander must save his estranged wife—the ship’s captain—and hundreds of passengers when a vengeful hijacker turns the vessel into a weapon aimed at a fuel terminal.
