Death Timeline Guide — Marking Every Death in Chronological Order
The death timeline is one of the key investigation tools in The Incident at Galley House. As you determine which characters died and approximately when, you mark their deaths on a chronological timeline that helps you visualize the sequence of events. This guide explains how the timeline works, when to mark deaths, how to refine your timeline as you gather more evidence, and how the chronological order of deaths connects to the broader mystery.
How the Death Timeline Works
The timeline is a visual representation of events at Galley House on the night of the incident. It is divided into segments corresponding to the scene timestamps (01 through 26 in Part 1), and you can place markers indicating when each character died.
Timeline Interface
The timeline interface allows you to:
- Mark a character's death at a specific point in the chronology
- Update or remove markers as your investigation reveals new information
- View the overall sequence of events and deaths at a glance
- Compare death order with scene timestamps to identify patterns
The timeline is a working document, not a final submission. You can change your markers at any time without penalty. This flexibility is important because your understanding of the death sequence evolves as you view more scenes.
When the Timeline Becomes Available
The timeline tool becomes available after you have viewed several early scenes and the game introduces the deduction system. Once available, you can access it at any time during your investigation.
When to Mark Deaths
Mark Early, Refine Later
The most efficient approach is to mark deaths as soon as you have a reasonable hypothesis, even if you are not certain. This earns you the Death Note achievement on your first marking and creates a working timeline that you can refine as you gather more evidence.
Confidence Levels
Use a simple confidence scale when marking deaths:
- High confidence — You witnessed the death directly or have multiple confirming evidence sources
- Medium confidence — You have strong indirect evidence (dialogue references, absence patterns)
- Low confidence — You have a hypothesis but limited supporting evidence
Mark deaths at any confidence level — the timeline is a tool for organizing your thinking, not a test of your accuracy. You can always update a marker when you gain more information.
The Death Note Achievement
The Death Note achievement triggers the first time you mark any death on the timeline, regardless of whether your marking is correct. This is one of the easiest achievements to earn — as soon as the timeline is available, mark your best guess about which character died first.
Determining Death Order
Establishing the chronological order of deaths is critical for understanding the events at Galley House. Here are the key strategies:
Scene Timestamp Correlation
The most reliable method for determining death order is correlating deaths with scene timestamps. If Person 3 appears in scenes 01 through 08 but not in scenes 09 through 26, their death likely occurred around timestamp 08-09. If Person 7 appears in scenes 01 through 15 but not after, their death occurred later.
Track character appearances across timestamps using a simple table:
| Person # | Last Scene Appearance | Estimated Death Window | Confidence |
|---|---|---|---|
| 1 | Scene 20 | Between 20-21 | High |
| 2 | Scene 14 | Between 14-16 | Medium |
| 3 | Scene 08 | Between 08-10 | Medium |
Cross-Referencing Death References
When one character references another character's death in a scene, the referenced death must have occurred before that scene's timestamp. If Person 4 says "I found him" in scene 12, the "him" (whoever it is) died before scene 12.
Build chains of death references:
- If Person 1 references Person 5's death in scene 10 → Person 5 died before scene 10
- If Person 3 references Person 1's death in scene 15 → Person 1 died before scene 15
- Therefore: Person 5 died before Person 1
Location-Based Ordering
Deaths at specific locations often follow patterns. The Chapel (CH), being the supernatural center, may be the site of later deaths connected to the meta-plot. The ground-floor rooms (EN, LI, KI, DI) tend to host earlier events. Upper-floor rooms (VI, HE, OS) may host later, more isolated deaths.
The Escalation Pattern
In mystery narratives, deaths often escalate — the first death is surprising, the second is alarming, and subsequent deaths create increasing panic. Watch for scenes that reference the "first body" or "another death" — these references establish relative ordering even without absolute timestamps.
Common Timeline Challenges
Simultaneous Deaths
Some characters may have died at approximately the same time. The game may not clearly distinguish the exact order of near-simultaneous deaths. In these cases, mark them as close together as the timeline allows, and note that the exact order is uncertain.
Ambiguous Deaths
Not every death is clearly shown or referenced. Some characters may have died off-screen, with their fate revealed only through absence or indirect dialogue. For ambiguous deaths, use the keyword search tool to find all references to the character and determine the most likely death window.
The Hidden Characters
Person 12, Person K, and Rupert Galley are hidden characters whose fates may complicate the timeline. If a hidden character died during the incident, their death must be placed on the timeline alongside the known characters. Finding evidence of hidden character fates requires viewing specific hidden scenes.
Changing Your Mind
As you view more scenes, you may need to revise your timeline significantly. A death you thought occurred early may be revealed to have happened later. Do not hesitate to update your timeline — the game's flexibility allows unlimited revisions.
Timeline and the Meta-Plot
The chronological order of deaths is not just a bookkeeping exercise — it connects directly to the meta-plot. The sequence in which characters died reveals information about:
- Who was targeted — If deaths follow a pattern (family members first, then servants, then guests), the pattern reveals the killer's priorities
- The escalation of danger — How quickly did the situation deteriorate? A rapid escalation suggests an external trigger; a slow escalation suggests internal conflict
- The role of the supernatural — If supernatural events coincide with specific deaths, the connection illuminates the meta-plot
- The surviving witness — Eve Dauer's position in the timeline reveals what she witnessed and when she escaped
The Inciting Incident Connection
The Inciting Incident achievement requires understanding the root cause of the events. The death timeline provides a framework for identifying the inciting incident — the event that set everything in motion. The first death in the sequence may be directly connected to the inciting incident, or it may be a consequence of events that occurred before the timeline begins.
Advanced Timeline Techniques
Reverse Chronology
Instead of building the timeline forward from scene 01, try building it backward from the end. If you know certain characters survived until late in the sequence, start with the confirmed late deaths and work backward. This approach can be faster because late deaths are often more clearly documented.
Cluster Analysis
Group deaths by location rather than by timestamp. If multiple deaths occurred in the same location, they may share a cause or be connected to the same sequence of events. Location-based clustering can reveal patterns that timestamp-based analysis misses.
| Location | Deaths at Location | Possible Connection |
|---|---|---|
| Chapel (CH) | Multiple | Supernatural cause |
| Kitchen (KI) | Multiple | Poison or domestic violence |
| Upper floors | Multiple | Isolation-related |
| Entrance (EN) | Multiple | Escape attempts |
The Elimination Method
If you have determined that 10 of 11 characters died and identified the death windows for 8 of them, the remaining 2 deaths must fill the remaining gaps in the timeline. Use the elimination method to place the unknown deaths in the available windows, then verify by checking whether the proposed sequence is consistent with the dialogue evidence.
Timeline and Achievement Progression
| Achievement | Timeline Connection |
|---|---|
| Death Note | First death marking on the timeline |
| Still Alive | Identifying Eve Dauer as a survivor on the timeline |
| Researcher | Viewing enough scenes to populate the timeline |
| Inciting Incident | Understanding the root cause through timeline analysis |
| Spectronoeticist | Viewing all death scenes to confirm the complete timeline |
Building Your Final Timeline
When you believe you have determined every character's fate and death order, review your timeline for internal consistency:
- No character appears in scenes after their death — If Person 5 is marked as dying before scene 10, they should not appear in scenes after 10
- Death references are consistent — If Person 2 references Person 7's death in scene 12, Person 7 must be marked as dying before scene 12
- The sequence makes narrative sense — The death order should tell a coherent story about the escalation of events
- Present-day evidence confirms your timeline — D&M records and Part 2 scenes should be consistent with your reconstruction

FAQ
Do I need to mark every death correctly to complete the game?
You need to determine every character's fate and cause of death to complete the Level 1 deductions. The timeline is your tool for organizing this information. The game confirms or rejects each submission, so you will eventually get every death correct even if some initial markings are wrong.
What if two characters died at the same time?
The game accounts for near-simultaneous deaths. Place the markers as close together as the timeline allows and note the ambiguity. The game's verification system will accept reasonable interpretations of simultaneous deaths.
Can the death order change between playthroughs?
No. The death order is fixed because it is determined by the game's narrative. The Incident at Galley House tells a specific story with a specific sequence of events. Your task is to discover that sequence, not to create it.
How does the timeline help with the meta-plot?
The death sequence reveals the pattern of violence at Galley House. Understanding who died first, who died last, and how the deaths escalated provides context for the meta-plot — particularly for understanding what triggered the events and whether the deaths were random or part of a larger pattern.
