The Posthumous Investigation Locations — All Areas, Evidence & Time Windows in 1937 Rio

🏛️

Primary 🕐 07:00–22:00 (most rooms)

Cubas Estate — Main House

The central location of the investigation. The estate is the victim's home and the scene of the murder. Multiple rooms are individually accessible — the entrance hall, parlour, study, kitchen, and garden each contain distinct evidence.

🔍 Investigation Tip

The estate's rooms operate on micro-schedules — the study's 10:00 accessibility window is created by Marie Grant's departure. Time your visits accordingly.

🔎 Evidence Available

Study financial document (10:00+ window)
Second bedroom examination (requires prior knowledge)
Evening rounds testimony (Constância, 19:00)

👤 NPCs Present

Marie Grant (07:30–10:00)
Constância (07:00–21:00)

🌿

Time-Critical 🕐 07:00–07:45 (dawn window) · 14:00–16:00 (afternoon)

Estate Garden — Dawn Window

The estate garden has two distinct access windows with completely different characters and content. The dawn window (07:00–07:45) contains Dona Eulália's critical monologue. The afternoon window is a standard conversation area.

🔍 Investigation Tip

The dawn garden is the single most time-critical location in the game. Arrive at 07:00 on any loop where you need the alibi testimony. You have 45 minutes before the window closes.

🔎 Evidence Available

Dona Eulália dawn monologue — Opportunity chain alibi contradiction testimony
Afternoon: standard conversation node with Constância

👤 NPCs Present

Dona Eulália (07:00–07:45 ONLY)
Constância (14:00–16:00)
Isabel Ferreira (11:30 morning walk)

☕

🕐 08:00–22:00

The Café — Largo do Machado

The social hub of the investigation, modelled on the historic cafés of 1930s Rio's Largo do Machado neighbourhood. Most suspects pass through during the day, making it the most information-dense single location. The private meeting window (12:15–12:45) is its most critical feature.

🔍 Investigation Tip

The café rewards patience. Arrive early to catch suspects at different moods, stay through the 12:15 meeting window, and return at 14:00 for the Alberto Nunes meeting.

🔎 Evidence Available

Private meeting testimony — Leonora + Thomas (12:15–12:45 window)
Alberto Nunes + secondary character meeting (14:00)
General testimony from 6+ suspects across the day

👤 NPCs Present

Breakfast traffic (08:00–10:00): multiple suspects
Leonora Vasconcelos (12:15–13:00)
Thomas Whitfield (13:00)
Alberto Nunes (14:00)

⚓

Time-Critical 🕐 11:00–17:00 (daytime, restricted access) · 18:00–22:00 (evening, full access)

Port District — Cais do Porto

The port district has two completely different access states. During daytime, a blocking NPC restricts entry to the public quay area only. After 18:00, the full district opens, revealing a new accessible area with the game's critical physical evidence node for the True Ending's extended Means chain.

🔍 Investigation Tip

Plan at least one loop specifically around the port evening window. Do not let day end at 17:00 without attempting it at least once. The evidence node there is not available anywhere else.

🔎 Evidence Available

Evening physical evidence node — True Ending Means chain (18:00+)
Possible private meeting observation (18:00+ if both suspects present)
Daytime: Thomas Whitfield conversation node (11:00)

👤 NPCs Present

Thomas Whitfield (11:00 daytime)
Evening: varies by loop — possible Sebastião Monteiro + secondary suspect

📜

Secondary 🕐 09:00–17:30

Alberto Nunes — Legal Office

Alberto Nunes's legal office is an off-estate accessible location that most players visit but underuse. The office contains documentary evidence about the will's contested provisions — additional context to the study financial document — and is the only place to speak with Nunes before his 11:00 estate visit.

🔍 Investigation Tip

Visit before 11:00 to catch Nunes before his estate visit. The second legal document in his office is the True Ending's secondary conspirator Motive chain anchor — do not miss it.

🔎 Evidence Available

Will provision documents (accessible after study document found)
Second legal document — secondary conspirator Motive chain anchor

👤 NPCs Present

Alberto Nunes (09:00–11:00, returns 17:30)

⛪

Secondary 🕐 07:00–20:00

Parish Church — Igreja de Nossa Senhora

Padre Álvaro's church is accessible throughout the day. Most suspects pass through at some point, making it a secondary social location. Padre Álvaro's confessional knowledge makes him a critical testimony source — but extracting it requires careful, non-confrontational dialogue.

🔍 Investigation Tip

Never approach Padre Álvaro aggressively. His confessional-duty refusals are more informative when you track exactly which topics he declines — each refusal narrows the field of what he's protecting.

🔎 Evidence Available

Padre Álvaro testimony (requires trust-building approach)
Incidental testimony from suspects encountered in the church

👤 NPCs Present

Padre Álvaro (07:00–11:00, returns 14:00–20:00)
Various suspects as secondary characters throughout the day

🎨

Secondary 🕐 07:00–11:30 (do not disturb) · 16:00–21:00 · 21:00 evening walk

Isabel Ferreira's Studio

Isabel Ferreira's studio on the estate grounds. Morning hours (before 11:30) she does not receive visitors — the door is closed. Afternoon she is accessible for standard conversation. The 21:00 evening walk outside the studio is her most candid window and contains the highest testimony density of any conversation in the game.

🔍 Investigation Tip

The 21:00 evening walk is Isabel at her most unguarded. Reach her there with maximum knowledge state. Do not reset before 21:00 on any loop where you're targeting Isabel's testimony.

🔎 Evidence Available

Afternoon: standard testimony nodes
21:00 evening walk: premium testimony — the most candid conversation in the game

👤 NPCs Present

Isabel Ferreira exclusively

🗝️

Secret 🕐 Accessible only via specific sequence

Hidden Location (Spoiler: Secret Study Archive)

A hidden room within the Cubas estate, accessible only by examining a specific object three times after exhausting Brás Cubas's ghost dialogue and returning to the study post-True Ending. Contains the material for the Literary Ghost achievement and additional narrative context.

🔍 Investigation Tip

This location has no gameplay impact on the investigation. It is narrative bonus content and an achievement trigger. Access it during Phase 3 after both endings are achieved.

🔎 Evidence Available

Literary Ghost achievement trigger
Narrative archive — extended Machado de Assis literary commentary
No Thinking Board evidence nodes

👤 NPCs Present

No living NPCs — ghost dialogue extended version

❓ Locations FAQ

How many locations are in The Posthumous Investigation?

There are 8 main accessible locations in the game, plus several sub-rooms within the Cubas Estate (entrance hall, parlour, study, kitchen, bedroom). The hidden location becomes accessible after the True Ending via a specific sequence. In total, approximately 14 distinct interactive spaces.

Which location has the most evidence?

The Cubas Estate as a whole contains the most evidence nodes across its multiple rooms. As a single-room location, the café is the most information-dense due to the number of NPCs who pass through it and the critical 12:15–12:45 private meeting window.

Can I fast travel between locations?

No. All movement is on foot with real-time transit. Knowing transit times between locations (learned in Loop 1) is essential for planning efficient routes that hit multiple time-critical windows in the same loop.

Are there any locations that only appear in specific loops?

No location is loop-exclusive. All locations exist in every loop, but several have time-window restrictions (the port evening area, the dawn garden, Isabel's evening walk) that mean their content is only accessible during specific in-game hours.

What is the hardest location to access and why?

The Port District's evening area (18:00+) is the most commonly missed critical location. Players who habitually reset before end-of-day never discover it exists. Planning a loop that stays active through 18:00+ is required to access its evidence.
