Master Crimes is the latest hit series from prolific television writer and showrunner Elsa Marpeau. This six-episode light and frothy police procedural follows two very different Parisian women as they come together to solve a series of six different, violent and perplexing crimes. Louise Arbus, an eccentric, exasperating, brilliant and immaculately groomed psycho-criminology professor at the Sorbonne. Robin's real-life wife, Anne Le Nen is Captain Barbara Delandre, a hyperactive yet practical law enforcement professional who always plays it by the book. Louise's skills are first called upon when a line from one of her books is found printed across a victim's back. She quickly assembles her investigative dream team made up of herself and four of her students, each with their own special skills that they bring to the table to help find the killer. Their eccentric approach to the investigation frustrates Captain Delandre and they quickly become her worst nightmare.
