Option 1 -> The inheritance (a sword and books) had no financial value; Hughie lived on money from his aunt instead.
Option 2 -> Hughie tried various professions but failed at all of them; the inheritance played no role in his career attempts.
Option 3 -> He hung the sword over his mirror as decoration and placed the books on a shelf between casual reading materials, showing he valued them only aesthetically.
