The Murder of Dr. Armando Costa

By: Welch, Mark E.

Lisbon is humming. But it isn't the music of Fado.

When eccentric detective Charles W. Radcliff III arrives in the "City of Seven Hills," he expects a retreat from the macabre. What he finds is a corpse coated in conductive cobalt-blue dust and a villa that functions more like a tuning fork than a home.

As historical tapestries vanish from the city's grandest halls, Radcliff and his stoic assistant, Reginald Pickering, uncover a terrifying truth: these stolen treasures were more than art-they were harmonic dampers designed to keep Lisbon's foundations from shaking apart.

With a fanatical historian pulling the strings of a physics-defying plot, Radcliff must race to stop a resonance sequence that threatens to collapse history itself into the Atlantic. In a race against vibrations and time, can Radcliff find the thread of truth before the city unravels?
