Title

Hello and welcome to the walkthrough for Agatha Christie - Hercule Poirot: The First Cases. This game is a classic point & click game with a lot of dialogue. There are a couple of Missable achievements, but with this guide you should get all of them no problem. Most choices don't matter except for the ones in the last chapter, but I will point all of them out as we play along. Prepare to dive into the world of Agatha Christie and to solve your first cases as detective Hercule Poirot.

Agatha Christie - Hercule Poirot: The First Cases - General hints and tips

General Hints & Tips


The game is pretty simple and straightforward. Most choices don't matter, but I will point out the ones that do. Unless I specifically mention it, the dialogue options don't matter, so just exhaust all the options. The areas are small and most investigation points are easy to find. You will even have a description for all the points before you investigate them, so there is a little chance to click on something wrong, if you pay attention. Some of the achievements for making certain amount of deductions unlocked a bit late for me, but everything should unlock before the end of the game.


Controls


Controls in this game are pretty simple. You move with cn_LS, interact with items and people with cn_A and zoom you camera in and out with cn_LT and cn_RT, respectively. I recommend having your camera zoomed out in all areas, sp you can see the entire area.

You can check character portraits with cn_Y and go to your mind maps with cn_X. You link the clues with cn_A. The controls are a bit finicky, so zoom in, in case you can't hit the clue.

Agatha Christie - Hercule Poirot: The First Cases - Story walkthrough

The game is pretty straightforward and in most cases it doesn't matter in which order you inspect the items or ask questions. If you inspect everything at every location you are fine. There are a couple of exceptions though and I will warn you beforehand about those (conversations options with a red marker instead of white are one example). The last chapter is a very specific one, so pay attention during that one. You have to make the correct choices during each conversation, otherwise you'd have to replay the entire game again. Most areas are very small and I inspected the items in a circular way. I will put some hints for how to find some harder to spot items, but otherwise just go around the area and inspect everything. I will mention transitions between rooms; if no transition is mentioned, the person/item is in the room, or you are automatically transported to the correct room. All the doors are labelled, so I won't be mentioning where the doors are. Some doors that are on the bottom or right side stick out a bit, but you can't see the door. Look for those if you can't find the door. There are always several investigation areas in your mind map. I will always mention which area to pick, but you can also see the number of Mind Mapable clues when you hover over the area, usually there is only one.


Prologue - The Bracelet


This chapter server as a tutorial, so you will have to do certain actions before you are allowed to continue. Just follow the tutorial, it is pretty quick. There are several characters which don't move from their places during most of the prologue. So if I forgot to direct you, assume they are where they were the first time you met them.

There is a missable achievement in the prologue. You have to inspect all available items, so pay careful attention to the items. You don't have to do them in order, but don't move into the next room, until you have everything from the current one. Also, you will make progress towards several missable achievements that span throughout more chapters.
