Sally and Joni head to Brussels on a mission to follow one of the strangest leads in the case: a mysterious coin cabinet inside Belgium’s Royal Library. As they dig through archives, flea markets, and fragile connections to Rick Blum’s past, they begin to uncover more about his aliases, his dealings, and possible links to stolen coins and foreign bank accounts. But a visit with one of his former victims — and a quiet moment of compassion — reminds them why they’re really here.
