Last update: 11 May 2016
As Sherlock, attach cog on the right side of millstone's axis.
The one he found before should be inserted on a stake on left from axis. But the mechanism still isn't working.
Switch on Watson and find a gear nearby barrier by chimney. Take it.
Move to exit and install at a big, rotating wheel on left from door.
Only then the millstone starts and breaks false wall. It turns out, that it contained Fergusson's corpse. As Holmes, take a paper from his left hand.
Then go to the exit and take a petrol from a bench.
