This is a
missable collectible based achievement.
This achievement appears to be buggy. It is highly recommended to make several manual saves throughout all three acts of the story or at least before picking up each note so you can revert back in case of anything.This is a written guide for the locations of all the notes related to Prudence (total 6): EDIT: There is another possible note that may be required for a now total of 7 notes. It is note number 4 on the list below and is titled "Clientele". Thanks to everyone who mentioned this note in the comments.

Loading a previously made manual save will work to pick up a note that you missed (I do not know if reaching a checkpoint after collecting it is required to save it though). After I had completed all three acts of the story, I did this to collect the last note that I needed which was "Mr. Kite's Instructions" as Arthur in Act 1. The achievement unlocked immediately after I collected it.
After collecting a note, make sure you do not die before the game makes a checkpoint. There may be a possibility that this has something to do with not getting the notes to count towards the achievement.
If the achievement bugs on you, read through the comments. Someone's experience with this achievement and how they got it to unlock may work for you.
This is a video guide for the locations of all the notes related to Prudence: (All credit for this video goes to Trophy Germany on Youtube)- The first note called "The Diary of Prudence Holmes" in Barrow Holm Safehouse, is on the bathroom sink in the maintenance room and not on the floor right beside the exit.
EDIT:
- A possible note titled "Clientele" which might be required (brings the total amount of notes needed to 7) is not in this video. For the location of this note use the written guide above.
