This episode is basically a copy of the first episode of the legendary Columbo: "Blueprint for Murder". Identical in the final. Jane is unable to engage the suspect. The only alternative is to convince the accomplice to accuse the guilty. But his accomplice loves her. Jane uses the same trick used by Lieutenant Columbo in the first episode of the series. Jene does believe the suspected that the accomplice has committed suicide and causes to make her confess that he don't loves him. At this point the accomplice confesses.
A few days after the death of Peter Falk I like to consider this episode as a tribute to the great actor.
