The titular detective of Young Sherlock seems to be in a legal bind in ScreenRant’s exclusive first look images from the upcoming Prime Video series.

One of the photos from our Spring TV Preview shows Sherlock Holmes (Hero Fiennes Tiffin) and James Moriarty (Dónal Finn) standing in front of a wanted poster for the former. The sign alleges that the young detective is a fugitive who needs to be turned in for murder and larceny. While Moriarty is one of Holmes’ adversaries in most literary adaptations, the previews suggest that the iconic sleuth was friends with the crime lord at one point in their lives.

The second image reveals Sherlock holding a large clock in a library. In the photo, he is seen standing between Moriarty and Max Irons’ character, Mycroft Holmes, the older brother of the famous detective. He is also a government official and one of the founders of the fictional London gentleman’s club, The Diogenes Club.
