For more than 70 years, “The Bad Seed” has been one of the most chilling dramas ever held on stage. The 1954 play by Maxwell Anderson, adapted from the novel by William March (prior to the 1956 film), tackles thorny issues of mental health, psychiatry, nature vs. nurture, juvenile development and psyche, trauma and responses to it, parenting, suicide, being blind to one’s assumptions, free will, and more.

All laid bare by a dispute over a school penmanship medal.

The Belfry Theatre production at The Cat in Carmel doesn’t shy away from any of this. Directed by Matt McKee, the story unfolds in a manner that even if you know everything that is going to happen, you can’t help but be drawn into the growing suspense.

Sixth-grader Olivia Cook plays central character Rhoda Penmark, the practically “perfect” daughter of Col. Kenneth and Cristine Penmark (Matt Spurlock and Lisa Anderson). If the name or her charming face in blonde braids look familiar, it may be that last year, she had the lead in “Ruthless,” the musical parody of “Bad Seed” (and “All About Eve”). This time, the singing and campy elements of the previous role cast aside, she proves to be as cold as a Terminator. Cook perfectly embodies the empathy deficit, narcissistic calm with moments of fury, imperfect attempts to be enough of a “nice” girl to get anything she wants, and unhindered calculations to remove obstacles.

Even now, in the era of True Crime programs and podcasts, it’s hard to see this in a cute tween girl; adults in the Eisenhower era didn’t stand a chance.

Lisa Anderson, as increasingly anxiety-ridden Christine, gives us a reminder that she is as capable of award-worthy performance as her husband Matt (who provides a radio voiceover). What starts with a constant vague sense of unease, accompanied by disturbing dreams, grows into ever darker suspicions as each dread becomes confirmed.

Daughter of criminologist turned radio star Richard Bravo (Jamie Kenjorski, who we’ll meet later), Christine takes advantage of her husband being away on assignment to The Pentagon to pick the brain of current criminologist and author Reginald Tasker (Nate Mecija). Joining them for lunch are her landlady and upstairs neighbor Monica (Desireè Black), accompanied by Emory (Thom Johnson), Monica’s brother.

Monica, whom Black plays with blythe confidence, has undergone Freudian therapy and feels herself an expert on the matter, swiftly diagnosing everyone. Tasker, ignoring her amateur prattle, relates advances in studying psychopaths, finding their conditions as much or more a product of birth than upbringing.

Meanwhile, at the school picnic, Claude Daigle – the boy who won the medal Rhoda not only covets but felt entitled to – mysteriously drowns. While others react as you’d expect, Rhoda comes home and calmly puts on her skates to enjoy her free afternoon. The only one to openly suspect her mood and motives is handyman Leroy (Aaron Beal), who has come to terms with his own neurodivergence and senses a fellow traveler in the girl. Though it is plain, even to a first-time viewer, that this apparently simple-minded man is not the principal villain, Beal’s edgy performance helps keep questions open to his motives.

The question of what really happened comes to consume Christine, especially after she is visited by Rhoda’s teacher Miss Fern (Samantha Kelly). We also meet Claude’s parents, Dwight (Tom Riddle) acting like a turtle wanting desperately to retreat into his shell, and Hortense (Becca Bartley), who has submerged her grief and need for answers in alcohol. The Daigles being working-class, feeling socially inferior, factors into the mother’s slurred rants – which Bartley delivers with perfect pathos – adding to the tragedy of their situation.

McKee’s daughters make big contributions to this production. Ava serves as assistant director, stage manager, and has a moment onstage as a Messenger. Her sister Kayla, who also works the light and sound boards at Center Stage in Lebanon, does so here with growing professionalism (light and sound designed by Bill Miller). Costumes, including some interesting mother/daughter combinations, are by Taylor Moss. Susanne Bush made the most of the Cat stage to design the roomy Penmark living room. Jennifer Poynter wrangled the props (where did she get the medal?). Makeup and hair by Victoria Garcia.

“The Bad Seed” takes root for one more weekend, Friday through Sunday, Sept. 11-13, at 254 Veterans Way in downtown Carmel. (Despite ongoing construction, accessing this street is fairly easy.) Get info and tickets at thebelfrytheatre.com or thecat.biz.
