Episode #2.1 - S2-E1
Trivia: In Season 2, Episode 1 (Finance Bros), Elsbeth solves the case based on a sound that is not there in a recorded call. If the call had been from the office, Ada, the computer would have responded to the name Ava. This is another case that is similar to a Columbo episode. In Columbo, Most Crucial Game, Columbo solves the case by noticing that the sound of a clock striking is not there in a recorded phone call, proving that the call was not made from the office, as the murderer claims.
Trivia: Elsbeth suspects that a "suicide" is actually a murder because the victim had recently used teeth whitening strips. This is similar to the last Columbo episode, "Columbo Likes the Nightlife", where the "suicide" victim has recently used mouthwash and trimmed his toenails. In each case they didn't believe a person would do those things right before taking his or her own life. Elsbeth also often turns around with "just one more thing" after walking away, just as Columbo often did.
