Sidney Johnson
From The Arthur Conan Doyle Encyclopedia

Fictional character.
In the Sherlock Holmes stories
- Sidney Johnson was the senior clerk and draughtsman at the Woolwich Arsenal office that guarded the Bruce-Partington plans (BRUC 203).
- He was 40, married with five children. He was a silent, morose man, but he had, on the whole, an excellent record in the public service. He was unpopular with his colleagues, but a hard worker (BRUC 203).
- He locked the plans in the safe on Monday evening (BRUC 215), was the last man out (BRUC 480), and said his safe key never left his watch-chain (BRUC 502) while Sir James Walter kept the door keys on one ring (BRUC 496). He doubted foreigners could build the boat from the seven recovered papers alone (BRUC 517).
- Sherlock Holmes made a methodical on-site check of the Woolwich office where the plans were last secured with Johnson observing (BRUC 527). He then had Johnson close the shutters and noted they didn't meet in the center, meaning an outsider could have seen activities inside the room (BRUC 531).
