What happens
Lecoq and Father Absinthe painstakingly track the footprints of the two women from the Poivrière crime scene through the snow, using plaster casts to preserve evidence. Despite losing the trail at the Rue du Chevaleret, Lecoq deduces the fugitives hailed a cab and resolves to find the driver the next day. Meanwhile, local vagabonds witness the detectives' lantern moving eerily across the plain, mistaking it for a will-o'-the-wisp.
