The Testament of Sherlock Holmes Hints

How can I get the grating's panel cleaned off?

  • 1 of 5: You'll need some sort of rag or cloth.
  • 2 of 5: Go back the way you came and look for one.
  • 3 of 5: Get back on the boat and examine the hotspot that's inside it.
  • 4 of 5: That'll get you a close-up of an old scarf, which you can click on to take.
  • 5 of 5: Return to the grating and get its close-up again, then pick up the scarf and wave it around over the dirty panel until it's as clean as it can get.
