Viewing Saunière's Corpse

Fache leads Langdon to the spot where Saunière's naked body lies on the parquet floor, arranged in the shape of a pentacle with a bloody star drawn on his abdomen. Langdon explains that the pentacle is a pre-Christian symbol of the sacred feminine and the goddess Venus, not devil worship. Fache then reveals a hidden message written in invisible ink on the floor: a series of numbers and the phrases 'O, Draconian devil!' and 'Oh, lame saint!' Langdon is baffled by the cryptic message.
