How to unlock the Detective historian achievement in Call of Cthulhu - Definitive Guide

For those who don't like videos, here's a written list of the books you need to find.

Chapter 4 (Volume 2) -- Easily missed. On the ground to the right of the first cave painting. If you get to the jump and haven't seen it yet, you've gone too far (and if you jump, you can't go back again).

Chapter 6 (Volume 3) -- In Francis Sander's office. on the desk with the table cloth. Its the same room that Cat is in/the one before the museum.

Chapter 7 (Volume 4) -- In Algernon Drake's shop. Upon starting the chapter, enter the room to your immediate left and its on top a stack of books.

Chapter 9 (Volume 1) -- In Fuller's office at the beginning of the chapter. Its in Fuller's desk, in the right hand side drawer. NOTE: This requires an investigation check to succeed. If you fail, IMMEDIATELY dashboard out and reload the game so you don't miss it.

Chapter 13 (Volume 5) -- In the first part of the Whaling Station (before smashing through the wall). Its in the room at the front right, inside the bottom drawer of a filing cabinet. Get it before you cut the rope.

I haven’t got to the Investigation check one yet, but how do you know if it’s going to fail, there’s chimes for success right?

Thank you for the guide. If I am right the chapter 7 book is not in the left room but at left corner of the main hall itself. The book in the left room also something related to volume 4. But when books related to this achievement is picked up, Edward comments that this another volume for the collection. He commented for book at left side corner of main hall. Worth adding because it may be easily missable too

I had all 5 books in my inventory, no achievement. Can the chapter 9 investigation check be failed, but the book still be obtained?

No -- if the investigation check is failed, you wouldn't be able to discover the right hand desk drawer, and thus won't be able to pick up the book. My suspicion is the achievement glitched out on you. Hopefully, it will unlock on a subsequent run (should you have any left). Let me know how it goes.

@UFO Hive, Yeah, me too. I have all 5 diaries in my inventory, definitely did not fail the investigation check in chapter 9 but no cheevo. This is literally the 3rd glitched achievement in this game on me... Glitched for the occult books (for sure found them all) and for accepting help from Drake even though I definitely did choose "Yes" while talking to him. Super annoying

*EDIT* They all randomly popped today for some crazy reason, almost 24 hours later. I'll take it I guess LOL

@DoomScott I'm glad it unlocked for you. This game is glitchy in terms of achievements -- you never know if its a temporary thing or if it just won't unlock until another playthrough. Glad it worked out for you.

Thanks for taking the time to type all of this out, I am one who prefers reading. Sometimes the videos are helpful, then other times they’ll show you what to do but do it so fast that you have to rewind & rewatch. Plus I like things to the point, and I don’t have the patience for over reacting YouTube hipsters

Checks are done silently in the background (and don't make noise when successful). The only way to know you failed your check on the chapter 9 volume is if you open the right hand side drawer and you don't see the memoir.

You cannot repeat checks, as once you fail its failed for the rest of the game, hence why you immediately want to dash out and close the game so you don't accidentally save your game with the failed state. As the check is done when you open the drawer, you can try over and over again assuming the game doesn't save after you open the drawer.

Ok, I’m about to do it now, so I’ll look for a book and be ready to press home..

EDIT: Well it’s there so all is fine. I guess having 100% investigation by this point is a good thing.

There are only five magazines, one of them is in a locked box, so don't forget to download "Investigation" to increase the chance of opening the lock.

Chapter 4 - in the cave next to the rock paintings, there will be a skeleton in the hand whose hand was crushed by stones.
Chapter 6 - in the room with Cas, the diary lies next to the fireplace.
Chapter 7 - immediately at the entrance to the store, to the left of the front door.
Chapter 9 - in Fuller's office desk drawer, hacking required.
