DI Stella Hopkins is a Detective Chief Inspector at New Scotland Yard. She first appears in "The Six Thatchers", where she is seen consulting with Sherlock about her Police cases via Video chat. These cases are part of a montage of Sherlock solving case and therefore can be counted as Off-screen cases as we don't know much about them aside from one of them being called "The Canary Trainer". She later visits Baker street in person to try and gain Sherlock's help with finding a missing Pearl case but Sherlock isn't interested and dismisses her.
