The bank box contains an old ledger and a stack of hospital admission forms. The forms place a nurse at Mei's birth who later disappeared; one form has an illegible signature—but the stamp matches the one on the photograph from mediation. The ledger contains a line: "Moved per order E." The "E" looks like Eleanor's initial. The ledger also holds a letter, brittle and yellowed, addressed to a woman named "L." whose name Mei still does not know.
Cliffhanger: Inside the letter is a clue: a childhood lullaby line that Mei recognizes from a memory she had tried to forget.
