Sherlock Holmes vs. Jack the Ripper Hints

Why won't it move?

  • 1 of 4: Stand back and look at the ground in front of the trolley.
  • 2 of 4: There's a small downhill slope right in front of it, so what's keeping it from rolling downhill?
  • 3 of 4: Check the two front wheels of the trolley to find that they're blocked with stones.
  • 4 of 4: Remove both stones to make the trolley movable.
