When the first body is found posed like scripture, the NYPD believes they're dealing with a religious extremist.
They're wrong.
The murders aren't just ritualistic - they're scholarly.
Dr. Mathias Green, a former divinity professor turned criminal profiler, recognizes the pattern immediately. Each killing follows precise theological structure. Each scene is a verse. And each message points back to a life he thought he'd left behind.
The killer calls himself Psalmist13.
And he isn't quoting scripture - he's responding to it.
As bodies begin to surface across New York City, Mathias is forced into a case that mirrors his own academic work, his past lectures, and the students who once listened too closely. With no-nonsense NYPD Captain Julia Halpern and sharp-witted tech analyst Lennox Rivera, Mathias races to interpret the next verse before it's written in blood.
But this killer isn't testing faith.
He's testing responsibility.
Because the final psalm won't just end in death -
it will expose the man who inspired it.
And the answers Mathias uncovers will not stay buried.
Book One in the Mathias Green Mysteries - a dark psychological thriller series where theology, intellect, and violence collide.
The investigation doesn't end here. In Book Two, Mathias Green faces a truth even scripture can't protect him from.
