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.
