Between Heaven and Hell. Pride - atthew Lewis

A Vatican Cardinal has been found dead before a Bernini sculpture - arranged with the patience and precision of someone making an argument they are entirely certain of. Beside his hand: a square of aged vellum. One word in Latin.
Superbia. Pride.
Detective Sonya Logan has forty-eight hours before Rome becomes a diplomatic incident. What she finds is not a crime of passion. It is a lecture - constructed by someone who has spent decades studying how sin expresses itself in human psychology, and who has identified the Cardinal as his most compelling subject.
The killer attended the Interpol briefing. He left his academic fingerprint at the scene for the only reader he believed capable of finding it.
He was right.
Working alongside Mason - an ex-priest turned investigative journalist who speaks Augustine from memory and reads crime scenes like sermons - Sonya follows a trail of vellum and iron gall ink through the eternal city. What she discovers is more unsettling than a single murder: a curriculum. Seven sins. Seven European cities. Seven lessons already planned.
Rome is only the first.
Between Heaven and Hell: Pride is the opening novel in an eight-book series where faith, desire, and moral reckoning collide across the cities of Europe - one sin, one city, one lesson at a time.
