Incest, murder, necrophilia ย— howย’s that for a little winter pick-me-up? Leave it to Ira Levin, author of the sinister Rosemaryย’s Baby and the pins-and-needles–producing Deathtrap, to take the genre of psychological thriller to a whole new level. In Veronicaย’s Room, Susan is out on a date with a young lawyer. They meet a slightly odd elderly couple. The seemingly gentle old souls tell Susan sheย’s a dead ringer for Veronica, an invalid who died while in their care in the 1930s. They still look after Veronicaย’s crazy, now elderly, sister, whoย’s on her deathbed. The two ask Susan to dress up like Veronica, circa 1935, and provide some solace for the dead womanย’s sister. After some prodding, Susan agrees; she promptly ends up dressed in the dead womanย’s clothes. Then the fun really starts. In the end, Susan learns what every young woman needs to know ย— donย’t go home with anyone who asks you to pretend to be a dead girl! 8 p.m. Fridays and Saturdays.
