The Adventures of Sherlock Holmes: Series 1- The Norwood Builder

"All my instincts are one way and all the facts are the other."

A superb mystery this episode, with Holmes slower on the uptake than usual. It's also the perfect introduction to the perennial Inspector Lestrade, with a battle of wits between them shaping the whole story. The device of having the main suspect for the crime be Holmes' client is a superb one. As is the gradual revelation that the "victim" was not murdered, but simply wanted to have a man hanged just because the man's mother once rejected him.

This one makes you feel clever as a viewer; I admit I may have remembered Conan Doyle's original short story, but I guessed what was going on before Holmes did. Watson, too, plays a genuinely useful investigative role here. And the revelation at the end is truly dramatic and entertaining. I'm genuinely struggling to find a bad episode.
