- At 88 years old, this is easily the oldest case featured on the series to date. It's 11 years older than the second-oldest case (and previous record holder) in "Beautiful Little Fool", a 77-year-old case from 1929 solved in 2006. In both cases, everyone involved had since died except for an elderly woman, who was a little girl at the time, who unwittingly gives a clue to the killer's identity. Also, in both cases, the now-deceased killer had left a voice recording confessing their actions. Both episodes also feature a subplot involving Lilly's mother.
