Arthur Clyde

Arthur Clyde also known as The Killer was the main antagonist of the first four installments of the Murder series. Before his initial death and revival, he was Ravélei Halla-Clyde's husband and Brad Clyde's legal father. He learned from his therapist, Greg Hudson, that his son had been switched at birth with another baby, Braedon Harris; learning this started his initial killings.

Following the birth of his son, Arthur began suffering from various mental disorders, including black outs and memory loss, the stress of fatherhood weighing heavily on his mental health. Initially, after killing several people including Ravélei, Greg, and two of Brad's best friend, Ellis Jones and Karla Tate, he was shot and killed by Officer Danny Chung. His body, left outside while a storm approached the area, was struck by lightning and reanimated him into an even stronger killing-machine.

He was portrayed by October Amat.

Description
Arthur is described as "tall, dark, mysterious in all the wrong ways." He is seen as a loving husband and a proud soon-to-be father during the reveal of his backstory. Following his journey into parenthood, his mental health began to deteriorate over time, eventually causing several mental disorders to form. Upon learning that his wife and therapist kept his son's true identity from him, he snapped and murdered them both - thus starting his many years of killings and indirectly causing many deaths.
