Start with Kate’s letter after the credits

Finish the main game, choose Continue and read Kate’s letter in the carriage. It concerns her missing brother and gives the clue “The crow awakens at five past four.” Open the notebook to revisit the chapters below.

The first requirement in the original letter-chain guide is story completion and Kate’s letter; it does not say you must already have all 49 achievements before starting. The final telescope reward can be your last one, but the unrelated optional chores are not substituted for these letters.

Day 1 Morning: set the alarm to 4:05

  1. Replay Waking up Aldous

    Choose Day 1 Morning’s Waking up Aldous task in the notebook. Obtain the Toy Soldier’s clock hand as in the morning routine.

  2. Set the different time

    Fit the hand and set the alarm to 4:05, not the normal 7:00.

    Checkpoint: A letter falls out. Open and read it for the bathroom clue.

Day 2 Evening: the four wall pictures

Replay Day 2 Evening · Helping with Bathing and use the wall pictures, not the moving soap box. The original achievement guide gives this input: Alexandra → bathtub → suitcase → hand.

A different tile opens for the maze letter. This is not the ordinary six groups of four associations, and you do not need to finish the whole bath to perform the secret tile input. Read the letter before moving to the lab.

Day 3 Morning: follow the maze turns

Replay Day 3 Morning · Assisting in Alchemy. The maze clue’s left/right symbols identify the floor box. Enter Right, Right, Right, Left, Right, Left, Right, Right, Left—R R R L R L R R L.

Take and read the letter. During ordinary alchemy, the same box’s L L R R L R input gives matches; here it is the nine-turn maze route that produces the next clue.

Day 1 Night: use the letter’s constellations

Replay Day 1 Night · Searching the Attic and use the constellation box. This time the shapes come from the letter’s grouped drawings, not the first-night window observations.

On a narrow screen, scroll the table sideways to read all columns.

Hidden-letter constellation settings.
SettingPattern
Castle / hotel4 stars with three branches forming the inner marks of a peace sign.
Moon2 stars joined in a straight line.
Water3 stars forming a triangle.

Open the box and read the new letter about the ruin. Its drawing points to the wine-box mechanism in Dressing up for Dinner.

Day 3 Evening: wine box and colored bottles

  1. Replay Dressing up for Dinner

    Choose Day 3 Evening. Go to the cellar’s wine box and rotate its pieces to match the new letter drawing, rather than entering the ordinary 1643 arrangement.

    Checkpoint: Read the letter from the box.

  2. Arrange the three bottles

    Put bronze above the spiral, silver above the wavy/S-shaped line, and gold above the triangle with the horizontal bar.

    Checkpoint: The upper barrel opens a hidden route.

  3. Read the red-cloak note

    Follow the circular passage into the room with the red cloak, mask and green box. Click the cloak until a note drops, then open it.

    Checkpoint: The four earlier clues for the final box are now available.

Derive 6294 and inspect the ruin

On a narrow screen, scroll the table sideways to read all columns.

The final digits reuse earlier clues; the resulting code is 6294.

Numbered letter 92681373Use the new X marks to leave the third-position digit: 6.
House-window drawingThe highest arched window from the coffee painting gives 2.
Eye on the meat tableSight / eye matched IX: 9.
Lab symbolThe decoded number is 4.
  1. Open the hidden-room box

    Enter 6294 and take the telescope.

  2. Find the distant ruin

    Leave the cellar, take the door on the right and head left toward the dining room. Open the window showing the distant ruin and use the telescope.

  3. Inspect its window

    Zoom in on the ruin and look into the window.

    Checkpoint: The discovery concerns Kate’s brother and unlocks You’ve found him!

If the telescope view is not yet available, confirm you took the telescope from the hidden-room box and are at the window showing the ruin. The normal attic sky and the hunting view are different scenes.

The clip and its relation to the main ending

AppUnwrapper’s original achievement guide points to a short clip at the end of this discovery route and describes its purpose as showing who the servant was. After the telescope discovery, use the clip entry offered by your build; the original guide and its video (opens in a new tab) provide the viewing reference if you need to compare the endpoint.

The exact footage and a single button label across platforms have not been established by the supplied original-author text. This guide therefore gives the full supported unlock chain without inventing the clip’s individual shots or a “one year earlier” timeline.

The main ending has already transformed the servant and reached the carriage credits before this replay trail starts. The optional discovery adds context; it does not make the lab’s recipe a choice between two required endings.
