Agatha Christie - Hercule Poirot: The London Case - Walkthrough and Achievement Guide

Walkthrough and guide for all achievements

Introduction

Number of achievements: 46
Number of missable achievements: at least 6 (A rude awakening, A curious phrase, Johan Kristiansen, A perilous journey, Perkins, A true performance)
Minimum Playthroughs: 1, chapter select available
Free-Roam After Story: No
Does difficulty affect achievements?: No

This is a walkthrough including all achievements. I logged my actions as I was playing and unlocked all achievements in one playthrough. Some actions might seem confused or out of order, but I didn't experience any technical difficulties reported by some players so it might be a good idea to follow them.

Inspecting all objects was always my first step in every location, usually in clockwise way.

Objects to inspect are numbered.
Deductions in mind maps are shown in frames.

Choices don't matter until the final chapter where you can fail some conversations and miss one achievement.

Some achievements span across multiple chapters. I didn't mark the progress in this guide since all of them are story related and therefore unmissable.

*Note: It's possible more achievements are actually missable. These were the ones I found during my playthroughs.

Thank you to NS Plover for pointing out missing achievements.

@NS Plover - You're absolutely right. I've checked my notes and even in this very guide it does say that the Johan achievement unlocks after talking with Hastings. Somehow I thought it would pop right after reading the letter. Definitely missable.

I'll add both achievements as missable. I'll have to play it one more time and try to do the absolute minimum to progress to see what can be missed. I just need to wait a while, the game is still fresh in my memory.`

[NS Plover]

@catnip - A curious phrase is also missable, the game will allow you to open the safe without doing the requirements of interacting with the notepad and/or looking at the dictionary after. And you can continue and complete the game without.

Not entirely sure how many other achievements can be missed - it does seem like most can't...

Anyway - I think your guide is great! Thanks for posting it.

[NS Plover]

@catnip - with Johan - you can view everything in the safe and do all the matches and not get it if you miss a conversation with Hastings - I forget the exact wording - about his affair with Irene.

@NS Plover These were my discoveries over the course of three playthroughs and single chapters. The sample was very tiny naturally and so errors are possible. Tracking achievements is almost impossible in this game with literally zero information about them or even any popup when obtaining them.

I genuinely forgot about the "A rude awakening" being missable, thank you.

As for the "Johan Kristiansen" while technically it is missable, you would have to intentionally break the inspection section of the safe and skip the letter. It's highly unlikely anyone would do that.

Perhaps I should remove that section entirely to not confuse anyone.

[NS Plover]

I'm not sure who came up with 3 missable achievements. There are more than that.

It is easily possible to complete the game and not get:
A rude awakening
Johan Kristiansen

Anytime you do a match that doesn't have all the items filled in, if the correct match is there and you choose it, you will proceed and may not be able to gather those other pieces of info. Not sure if there are other achievements missable if you do this.

With a rude awakening, you can proceed the game without talking to Mortimer about Irene and no achievement...

Great guide! Hopefully you will also do one for Orient Express
