Selección Terror: ¿Quién mutiló a Evelyn?

This pulp horror serial, "¿Quién Mutiló a Evelyn?" (Who Mutilated Evelyn?), presents a mystery-thriller featuring Rosemary, a piano teacher who arrives in Mattersson seeking employment. Warned by journalist Leo Murray that the employer, Ronald Wynn, is a suspected murderer of the Greene family, she accepts the position anyway. When dismembered body parts arrive at Wynn's mansion—a woman's legs and arms, freshly severed—Rosemary witnesses Wynn's violent reaction. Police arrest him, finding evidence connecting him to four Greene siblings' deaths by shotgun. Wynn confesses and receives a death sentence. Subsequently, Wynn names Rosemary his heir to a $200 million fortune, contingent upon two conditions: she must witness his execution by gas chamber on the twentieth of next month, and live in the Mattersson house for three months. Leo Murray relays these bizarre terms, puzzling both characters as Rosemary suspects hidden motives behind this unexpected inheritance.
