Sinner Take All (1936) Timeline Explained – Every Event in Order

MacKelvey killed the Lampier family to seize control of their lucrative publishing businesses. He confesses that he needed more money to placate his wife Alicia and that eliminating the Lampiers would give him access to their business empire. The inheritance clause in Aaron Lampier's will, which split the estate equally among the children with charities as fallback, created a situation where killing all heirs would leave the fortune unclaimed, allowing MacKelvey to move in and take control.

Foreshadowing: Earlier, MacKelvey dispatches Ernie to find Lorraine, giving him direct access to investigate the family while positioning himself as helpful to the case.

Ernie staged a trap by spreading the word that Lorraine planned to flee at midnight, gathering all prime suspects at Frank Penny's nightclub to witness her departure. He had a doctor standby, knowing the killer would attempt to poison her. When Lorraine's drink was poisoned, the doctor saved her life in time. This setup allowed Ernie to observe who had the opportunity to slip the poison into her drink, which led him to identify MacKelvey as the culprit.

Foreshadowing: The earlier murders of Stephen and Aaron Lampier followed similar patterns of opportunity, suggesting the killer was close to the investigation.

David Lampier went into hiding after receiving a death threat, thinking he would be safer disappearing. However, when Ernie and MacKelvey finally tracked him down to his hidden safehouse, they discovered he had already been stabbed to death. The killer had found David's hiding place and eliminated him, making it appear as though the earlier car crash had claimed his life when he was actually still alive.

Foreshadowing: The death threat sent to David was mentioned early in the film, hinting that he was a target.

Stephen Lampier was killed as part of the systematic elimination of the Lampier heirs. After David was believed dead in the staged car crash (set up with a wire cable across the road), Stephen became the next target. The killer wanted to clear the path to the inheritance by removing all children who would inherit equally under their father's will. Stephen was found in his car with six shots to the head.

Foreshadowing: The will's clause stating the estate goes to charities if any child predeceases the patriarch created a clear motive for eliminating all heirs.

Frank Penny, who ran the nightclub where Lorraine performed, became a prime suspect. Captain Bill Royce of the Homicide Squad arrested Penny after Stephen's body was found in a car being driven by Penny's associate. However, the police lacked sufficient evidence to hold him, and Penny was released. While his nightclub served as the setting for much of the action, Penny was ultimately not the killer, MacKelvey was using him and his establishment as cover for the murders.

Foreshadowing: Penny's arrest early in the investigation created suspicion around him, diverting attention from the true killer.

Lorraine was targeted because she was the last remaining Lampier heir after her brothers and father were killed. The killer needed to eliminate all children to prevent them from inheriting equally under the will, which would block MacKelvey's scheme to seize control of the family businesses. Poisoning Lorraine at the nightclub was the final attempt to complete the inheritance scheme.

Foreshadowing: The pattern of killing all family members followed the logic of the will's inheritance clause.

• lorraine poisoning
• last heir
• inheritance motive

Aaron Lampier's will stipulated that his estate would be divided equally among his children, Lorraine, Stephen, and David, with charities as the fallback if any child predeceased him. This created a powerful motive for someone wanting to control the fortune: by killing all the children, the estate would go to charities, but MacKelvey apparently planned to exploit this situation to take over the businesses themselves. The will essentially turned the family into targets for anyone seeking control of the Lampier empire.

Foreshadowing: The will was mentioned early in the film, establishing the stakes of the inheritance.

MacKelvey was responsible for killing Aaron Lampier. The murder occurred when a man slipped into Lampier's suite and, after a struggle, flung him over the terrace to his death. This added another layer to the escalating murder spree that had already claimed Stephen and the apparently deceased David. The killing of the patriarch himself completed the elimination of the direct Lampier line.

Foreshadowing: The earlier death threats sent to Aaron Lampier foreshadowed his eventual murder.

David Lampier's car crash appeared to be a setup because investigators discovered a wire cable stretched across the road, indicating someone had deliberately caused the accident. This evidence suggested foul play rather than an accidental death, which is why Ernie began to suspect that the family was being systematically targeted rather than randomly attacked.

Foreshadowing: The threatening letters received by the family members hinted at a calculated plan.
