|Janet Key (1945 - 1992)
Mrs. Gawn Grainger
|I Don't Want to Be Born (The Baby; The Devil Within Her; The Monster; Sharon's Baby) (1975) [Jill]: Hits her head on a rock when the possessed baby pushes her into a lake.
Antony & Cleopatra (1981) [Charmian]: Presumably commits suicide by letting an asp bite her, after Ian Charleson enters and discovers Janet Lapotaire's body. (I haven't seen this version, but I'm roughly familiar with the play.)
