She is summoned to a crime scene that feels eerily performative: a successful tech entrepreneur is found dead in his luxury penthouse, cocooned in industrial-grade silk thread, posed like an insect trapped in a web. At the center of the display is a single playing card— La Araña from an obscure antique tarot deck.
