The Oblong Box

In 1865 Africa, Sir Edward Markham is violently scarred and disfigured during a voodoo ritual. Traumatized and desperate for a cure, he is taken back to England by his elder brother Julian Markham, who imprisons him in an attic to keep his disfigurement a secret. Driven mad by his confinement and believing that his brother is hiding more from him, Edward plots escape with the help of a servant named N'Galo. Their attempt culminates in Edward's apparent death, but Julian is reluctant to bury him without verifying his condition. A corrupt and ambitious doctor, Dr. Neuhartt, sees an opportunity and steals Edward's supposedly dead body for his own experiments, discovering that Edward is still alive.

Freed from captivity but driven by vengeance and guilt, Edward adopts a hooded cloak to conceal his appearance and begins to exact revenge on those who wronged him, leading to a string of murders. His actions bring turmoil and fear to London, attracting the attention of both the law and his brother Julian. As Edward's lethal campaign continues, more is unearthed about the dark secrets within the Markham family and the true nature of Edward’s curse. Julian's growing desperation to control the situation results in catastrophic encounters that threaten both their lives. As tensions reach a boiling point, revelations unfold that alter the course of everyone's fate involved in the deadly game of deception and retribution.
