Sherlock Holmes and the Stolen Emerald is a project that Céline started when she arrived in London. She wrote the script in June 2012 and used a crowdfunding campaign on Indiegogo to fund the film. In the next months, she recruited the crew and the cast, and the film was shot in January 2013 at the Barts Pathology Museum. It premiered at the Genesis Cinema in London on June 6th 2013.
The film was selected in several short films festivals, and was also screened in various steampunk conventions.
