On the nature of magic
(Book)

Helena Walton-Cisneros, known for finding answers to the impossible, has started her own detective agency. She takes on two new uncanny cases, both located in Paris - which itself is too much of a coincidence to ignore. In the first case, two English women claim to have seen the ghost of Marie Antoinette in the gardens of Versailles. The second case is the murder of a young woman working at the mysterious Melies Star Films studio outside Paris.
