Sherlock Holmes versus Arsene Lupin Hints

How can I solve Lupin's twelfth clue? (Sun)

  • 1 of 17: The Sun is the key here.
  • 2 of 17: The Sun is the centre of our Solar System.
  • 3 of 17: And you can find a model Solar System at one of the tables in the Permanent Exhibit Hall.
  • 4 of 17: Use it, and Holmes will tell you what to do.
  • 5 of 17: You will need to click each planet individually to see how many times it rotates around the sun, then add these values together.
  • 6 of 17: Starting from the inside, the values are:
  • 7 of 17: Mercury = 6, Venus = 5, Earth = 3, Moon = 13, Mars = 4, Jupiter = 2, Saturn = 1
  • 8 of 17: However, the trick here is to remember that the moon is not a planet.
  • 9 of 17: And, while orbiting Earth 13 times, it also orbits the sun along with the Earth.
  • 10 of 17: Therefore, it makes 16 revolutions, not 13.
  • 11 of 17: Add these values as the third paragraph tells you, to come up with a total of 37.
  • 12 of 17: Now take Earth, square its rotations (three squared equals nine), and multiply that by two, which equals 18.
  • 13 of 17: Now multiply those values. 37 multiplied by 18 equals 666. Add a thousand to this value to give a final answer of 1666.
  • 14 of 17: Maybe you should read up on that answer?
  • 15 of 17: Enter 1666 into the card machine in the reading room.
  • 16 of 17: Find the relevant book, at I-13-12.
  • 17 of 17: You will need to crouch down to take the final message.
