The Promise - S3-E2
Continuity mistake: At the start of the episode the date "October 23, 2003" appears onscreen, which is the night of the party where Laurie Dunne died. However, shortly after, we see the officer typing up the accidental death report and the year of death reads as "2004" and also later when Laurie's father shows the laptop to Stillman and Lilly, we see the date stamp "2004:10:23" on the image that Laurie had emailed.
Chosen answer: According to IMDb.com, it is Carly Simon.
