Off-screen cases refers to cases that Sherlock Holmes takes that are referred to at some point but are not described, or in the case of an adaptation, shown on screen.

Sherlock Holmes Short Stories and Novels Edit

Vatican Cameos Edit

This is briefly mentioned during The Hound of the Baskervilles, in which Sherlock Holmes says, "I was exceedingly preoccupied by that little affair of the Vatican cameos, and in my anxiety to oblige the Pope I lost touch with several interesting English cases".

The Giant Rat of Sumatra Edit

This is mentioned by Holmes in "The Adventure of the Sussex Vampire". He said; "Matilda Briggs was not the name of a young woman, Watson, ... It was a ship which is associated with the giant rat of Sumatra, a story for which the world is not yet prepared".

Sherlock (2010) Edit

These are a collection of cases that are either referenced in episodes or in the character blogs.

The Green Ladder Edit

Blog Entry: The Green Ladder

The Green Ladder is a case that Sherlock mentions just before being introduced to John Watson.[1] When Sherlock first meets John in the lab at Barts he borrows John's phone and texts an unknown person, probably DI Greg Lestrade, that he should arrest the brother if he has a green ladder. (A reference to an outline for a Sherlock Holmes story found among Conan Doyle's papers.)[citation needed]

The Aluminium Crutch Edit

Cases in "A Scandal in Belgravia" Edit

Dead pig Edit

Sherlock blood pig

At the start of "The Hounds of Baskerville" Sherlock arrives back at 221B Baker Street covered in blood carrying a harpoon in his hands. His appearance is due to a case which he managed to solve by shooting a dead pig with his harpoon. Sherlock says that he had to catch the tube back to the flat because the cabs would not let him in. (Possibly a reference to the murder of Peter Carey in the original books.)
