I Killed That Man

Nick Ross is executed in a prison room watched by the crowd. He says there has been no commutation and begins to reveal the true events behind the crime, hoping for release. Before the crowd can hear the full confession, he suddenly collapses and dies from a poison dart.

District Attorney Roger Phillips, his girlfriend Geri Reynolds, and Tommy begin sweeping the room for the murder weapon and reconstructing the scene. They search the occupants and arrange everyone back to their original seats to spot inconsistencies. The investigation is focused on uncovering who delivered the fatal dart.

Ross's character witness Lanning becomes a central suspect due to a cigarette holder that could double as a dart blower. He proclaims his innocence, but the DA arrests him anyway. The search for motive and means tightens around the room's occupants.

Geri Reynolds is sent to the prison and asked to get acquainted with Lowell King, a parole board appointee. This move aims to gauge King's involvement and potential influence over the case. The setup broadens the investigation beyond Ross's immediate circle.

Roger, reprimanded for arresting Lanning, asks Geri to interview Verne Drake, Ross's girlfriend. Verne defends Ross but admits he made a phone call from her apartment on the day of the murder. The interview adds new threads to the murky web of connections.

Verne receives a threatening phone call after Geri's visit. Roger assigns Detective Collins to monitor Verne and discovers the number belongs to King. He also spots a code on the back of King's business card hinting at a library connection.

King denies knowing Ross during questioning. However, Gordon, the butler, admits to having placed bets with Ross, tying the case to the King household. The suspicion widens to include the King circle.

Verne plans to leave town and accompanies Reed to the bank to settle the money she helped obtain for Ross's release. Verne dies suddenly after honking the car horn, leaving Reed implicated in the chain of events. The murder mystery deepens as money and motive intertwine.

Collins catches Reed when he tries to flee, halting the suspect's escape. Roger then discovers a poisoned dart embedded in the steering wheel that matches the one used on Ross, leading to Reed's arrest and freeing Lanning.

That evening, Geri Reynolds and Bates dine at Garrick's café and have their check declined. King arrives, leveraging his ties with Garrick, and offers to help. A waiter accepts King's check and takes it to Garrick's office, signaling the start of a money-moving scheme.

Garrick burns King's check and hands the waiter a roll of money, which King then gives to Geri, though he still settles Geri's bill. The evidence of corruption becomes more tangible as illicit funds surface. The alliance between Garrick and King grows more explicit.

Geri realizes the code on King's card points to a library book about toxicology. Tommy begins to pull records on the book while Roger contemplates the implications for King. Meanwhile, Geri accidentally drops her purse and discovers five $500 bills tucked in her wallet.

Tommy arranges a listening-in on a conversation between Garrick and King, revealing their shared protection racket. They hear Garrick believing the money was meant for King, tying the money trail directly to the two men. The stakes in the case rise higher.

King reveals that Geri is with him, prompting Roger, Bates, and Collins to rush to his house. King attempts to kill Geri with a poisoned dart, but Geri knocks him out with a vase, and Bates and Collins capture Garrick and his thugs.

King confesses to the murders of Ross and Verne and makes a final attempt to kill Roger. Geri intervenes to stop him, and he is subdued as Garrick and his henchmen are taken into custody. Roger invites Geri to join his staff, sealing the cooperative future of the investigative team.
