The Empty Sled [SFX: Snowmobile engine. Radio static] NARRATOR: Kira and Vik followed beacon stakes through whiteout. The freight sled sat beside the crevasse, empty, its cargo clamps closed around nothing. Pavel's tracker hung beneath the chassis. VIK TORR: Programmed route. No passenger. KIRA SOL: What payload did it deliver? NARRATOR: The sled battery was warm. Its log had been erased, but frost preserved a rectangular outline on the deck, the dimensions of an ice-core crate. At the crevasse edge, blue packing foam clung to a rope. [SFX: Winch ratchet. Ice cracking] KIRA SOL: Somebody lowered a core, not a body. NARRATOR: Back at Borealis, Eda revealed Pavel had found a mismatch in climate records. A famous warming spike attributed to the ice cores did not appear in satellite data. EDA LIN: He believed samples were swapped after drilling. If he was right, our flagship paper is built on manufactured ice. MATEO RUSK: Pavel accused everyone when funding reviews approached. NARRATOR: In freezer seven, Kira found sawdust from fresh-cut wood. Borealis contained no wooden crates. Supply aircraft used composite. The sawdust smelled of cedar, the material used in Mateo's private specimen chest.
