Staring at her mirror, prettifying herself for a gentleman caller, Stella Goldschlag is like any other glamorous lady of a certain age, keen to talk about the past and dragging out photo albums.
But as she ponders on the former-schoolboy-suitor-turned-journalist coming to visit we are slowly led into the 71-year-old's dark past.
It starts slowly with the odd anti-Semitic remark, cast in casually among the preening and talk of former lovers.
But soon we are faced with the real-life monster who reportedly sent 3,000 of her fellow Jews to their deaths.
Gail Louw's brilliant script feels natural, as Goldschlag's thoughts move between her current lonely life and her chequered past and she gets more involved in her story.
In one chilling scene Goldschlag stares straight out at the audience, explaining why she was good at her job - and the satisfaction she got out of it. In Elizabeth Counsell's bravura performance, her beauty strips away to reveal a hard mask.
The audience is still made to feel sympathy for her though as she talks about being a prisoner of the Gestapo, her departed mutti and vati, and her skills at hiding from the secret police - her Aryan looks allowing her to travel underneath the surface like a U-boat.
Once the war is over she sees herself as a victim of Fascism, questioning the audience what they might do in the same position.
It's a stark gem - designed to both shock and linger.
