At age 19, Sherlock Holmes is disgraced, raw, unfiltered, and unformed, when he finds himself caught up in a murder mystery at Oxford University which threatens his freedom. Diving into his first-ever case with a wild lack of discipline, Sherlock manages to unravel a globe-trotting conspiracy that will change his life forever.

Fitz's arrival disrupts the life of Deputy Chief Geneviève "Arch" Archambault, a Parisian transplant who is in Saint-Pierre for her own intriguing reasons.
As if by fate, these two seasoned officers — with very different policing skills and approaches — are forced together to solve unique and exciting crimes. Although the islands seem like a quaint tourist destination, the idyllic façade conceals the worst kind of criminal activity which tend to wash up on its beautiful shores. At first at odds and suspicious of each other, Arch and Fitz soon discover that they are better together... a veritable crime-fighting force.
Art Detectives
Art Detectives is a compelling new original crime series centered around the Heritage Crime Unit, a police department consisting of art loving DI Mick Palmer and straight-talking DC Shazia Malik.

Throughout the season, the artfully astute detectives encounter a fake Vermeer, Viking gold, a rare Chinese vase and items rescued from the Titanic. It's a rich and colorful world driven by greed, obsession, lust and revenge. Mick navigates these demanding cases while managing a budding romance with museum curator Rosa and the sudden reappearance of his charismatic father, Ron, who just happens to be one of Britain's most notorious forgers.
