The Gaslight Study (3D)
🕵️ A Sherlock Holmes game — The consulting detective himself
Sir Julius Pemberton lies dead in his study, and the household is very sure it was burglars. Step into a fully 3D Victorian room — firelight flickering, moonlight through the window, fog at the panes — and investigate in first person: walk with WASD, look with the mouse, and examine the port glass, the torn letter, the safe, the prints, and the ash. When your journal holds all five, accuse one of three suspects and hear the verdict. In the spirit of the great 3D detective games, in your browser, with nothing to install.

What it does
A real 3D scene
A fully furnished Victorian study in three.js: a living coal fire, gaslight, moonlight and shadows through a twelve-pane sash, and every surface — panelling, damask, a Persian rug — drawn procedurally in your browser.
Evidence that argues
Five clues that each eliminate somebody — the case solves by elimination, not luck.
The accusation
Three suspects, three statements, one verdict — and a solve-time best to beat.
How to play
-
1
Begin with the body — the examination opens the case.
-
2
Gather the five clues; Watson and Holmes remark as the picture forms.
-
3
Reconstruct the crime in three deductions, hear the suspects pressed — then name the killer.
A deliberate homage to the modern 3D Holmes adventures — one room, one case, honest clues, and a reconstruction before the collar.
Frequently asked questions
Is The Gaslight Study free?
Yes. It is a free 3D detective game that runs in your web browser, with no download, no account and no in-game purchases.
How long does the case take?
It is one room and one case, built to be solved in a single sitting. Your fastest solve time is saved in your browser so you can try to beat it.
Can I play it on a phone?
Not yet. It is played with a keyboard and mouse (WASD to walk, the mouse to look), so you need a desktop or laptop.
Is it based on a Conan Doyle story?
No. It is an original case written in the spirit of the canon, so even Holmes experts have to solve it from the evidence.
