The Testament of Sherlock Holmes Hints

Where can I find the handcuffs' key?

  • 1 of 8: Search the place to see if you can find any likely hiding spots.
  • 2 of 8: You won't be able to find the key until you get the handcuffs' code.
  • 3 of 8: After you do, examine the water basin that you diluted the reagent in.
  • 4 of 8: Examine the water in the close-up to find that Holmes apparently washed his hands there after digging around in some soil.
  • 5 of 8: That would seem to indicate that he hid the key in some soil.
  • 6 of 8: Go to the back area and check out the large plant that's next to the windows.
  • 7 of 8: Examine the plant to get a close-up of its base, then click around on the soil.
  • 8 of 8: When you uncover a key, take it. It's the one you need for the handcuffs.
