I can think of a better ending for this episode that would have gotten Warren Barrow (James Mason) off the hook for murdering Janet West (Angie Dickinson). All the writers had to do was come up with a rationale for Barrow to convince Tom Keller (Ed Nelson) to run to Janet's rescue at her apartment where Barrow was waiting to kill her. Instead, Tom went there on the suspicion that Barrow was going to do it. Barrow handed his weapon to Tom after pulling the trigger so both of their fingerprints would have been on the gun. It would then have been a matter for the authorities to figure out who the killer was, and since Barrow didn't look like someone the glamorous Janet West would have been involved with, he could have pressed that point and the suspicion would have turned to Keller as the jealous lover who barged in on them both. That might sound farfetched, but no more so than the way the story actually played out. I kind of like my idea, so I'm sticking with it.
