Anthony Horowitz is no stranger to Sherlock Holmes; his career as a crime writer was inspired by the canon and he’s written two pastiches (House of Silk, Moriarty) and a pair of novel series (the Daniel Hawthorne series, beginning with The Word is Murder and the Susan Ryeland series, beginning with Magpie Murders) which are homages to Sir Arthur Conan Doyle and his famous creation.

“Once Jonathan was on board,” Earl says, “no disrespect to Conan Doyle, but the whole thing just seemed to take on a life of its own! Genuinely a life of its own, because we’re now doing original stories.”

Between the show’s writing and acting and its connections to Sherlock Holmes canon, it’s got a lot going for it.
