Archaeologist Tamar Saticoy discovers a Roman mosaic on the floor of an excavation in Turkey. When she brings an official from the Department of Antiquities to see it, the mosaic is gone and a student assistant's dead body is on the site. Tamar manages to track the missing mosaic to Switzerland, where its disappearance seems linked to the theft of a hoard of Thracian gold.
