Installation:
Once the file is downloaded, go to the following path and put the files in the "L.A. Noire" folder and that's it, just go into the game and do it!.

D:\Mis Documentos\Rockstar Games\L.A. Noire\Profiles\4BCE6AFB\L.A. Noire

ATTENTION!:
Make a back-up of your original files, and then when you finish unlocking the achievement, put your original files back.

Resume the game, then look for the two clues which are “Bus ticket” and “Cunard Ascania”, then check the body of the man lying down, check the two pockets, don't forget to check the man's pockets because you won't be able to advance for Candy's interrogation, look at the screenshots.

Interview:
1. Whereabouts of Hammonds.
Lie (Magazine coupon).

2. List of odds recovered.
Lie (Bookmakers' payouts).

3. Plans to leave town.
Doubt.

Then, you have to follow Candy without being seen, you can't use the “incognito” mode, so be careful, I leave a video at the end of the guide of a person who shows you how to get the achievement.
