| Langdale Pike |
|Behind the scenes|
|Appearances||"Step Nine" (unseen)|
Langdale Pike is a CCTV observer at Trafalgar Square.
Pike appears to be a paranoid man who rather stay out of sight. This is seen when Sherlock Holmes tells Joan Watson that he does not have a cell phone because of GPS tracking software in the phone. Sherlock goes to Trafalgar Square with the purpose of getting the list of people who bought 3D printers from Langdale Pike.
Much like the original Langdale Pike, he is unseen and helps Sherlock learn the names of people involved in the case.
