Zorro S01E16 - Whereabouts

Sebastian Moreno, an author from Spain, arrives in the pueblo to write the story of Zorro and his true identity. He soon witnesses the hero saving Victoria and some guests from two robbers; he ignores how close he is while he is Don Alejandro's guest at the de la Vega hacienda, but accidentally triggers the secret mechanism of the fireplace door, luckily seen by Diego in time to stop him entering. The alcalde makes sergeant Mendoza follow Moreno everywhere for weeks, to no avail.
