At the heart of San Marino's most vibrant music festival, the unthinkable happens: DJ Ecciti, the star of the show, collapses on stage, turning a night of celebration into one of chaos and mystery.

Luigi Ferro is engaged by the festival's organizer, amidst the frustration with the local gendarmerie's slow progress, to untangle a web of deceit and danger.

As Ferro delves into the glittering world of music and fame, he encounters a trio of suspects—a rival DJ, a spurned lover, and a shady promoter—each harboring motives as complex as the tunes that electrify the festival air. But as seductive distractions and misleading clues cloud his path, Ferro must navigate through a maze of hidden relationships and secret deals that could be the key to solving the case.

Set against the backdrop of San Marino's scenic beauty, "The Rhythm of Death" is a story where the melody of mystery deepens, danger dances in the shadows, and for Luigi Ferro, every beat could be a clue leading to the shocking revelation.
