Achievements in this game are rather easy, only Arsene Lupin (Solve three Lockpick puzzles in less than one minute). can be problematic, so for people who like easy solutions - just press in the same order as I write:

There are 3 lockpicks in game:

1. Workshop - The Locker (Garage? Where the first detective puzzle is): it moves when you click 3 places Left Button, 2 places Right Button
   
   Solution: 2x Right, 2x Left, 4x Right
   
   
2. Museum on the 1st floor - The Door: it moves when you click 3 places Left Button, 5 places Right Button
   
   Solution: 2x Right, 2x Left, 1x Right
   
   
3. Jail - The Door: it moves when you click 2 places Left Button, 3 places Right Button
   
   Solution: 2x Left, 1x Right, 1x Left, 2x Right, 1x Left

Additional info: You don't have to finish all 3 locks under one minute to get achievements in only one playthrough, you can do it whenever you want, while it's still on the same profile in game.
