Sherlock Holmes versus Arsene Lupin Hints
How can I pass the second locked door, with the Roman Numeral lock?
1 of 10: Firstly, did you notice something fall when Lupin slammed the door as he ran off?
2 of 10: You can pick up some small metal pins from the floor below the lock.
3 of 10: Use these to make the equation true.
4 of 10: The first value needs to equal the second.
5 of 10: The sum will need to be in Roman Numerals, and will contain addition and subtraction.
6 of 10: In decimal numbers, the result of the sum is 81.
7 of 10: And the two sides read 22 + 7 + 52 = 100 - 23 + 4.
8 of 10: In Roman Numerals, the sum reads:
9 of 10: XXII + VII + LII = C - XXIII + IV.
10 of 10: Fill these values in with the spare pins, and the door will open.
