Chapter 01 · Opening service

Chapter 1: Arrival & Serving Mr. Aldous

Opening route documented

Enter the Vanderboom estate, sign the servant contract and complete Aldous’s first morning routine.

01

Arrival & contract

Complete the carriage and entrance sequence, enter the estate, then use the inked crow feather to sign the servant contract.

02

Morning porridge

Gather the breakfast ingredients, light the stove and prepare Aldous’s oatmeal porridge before serving it with the required additions.

03

Alarm & shaving

Restore the alarm-clock hand, set the morning time, wake Aldous and complete the shaving clue chain.

High-traffic checkpoints: servant contract, porridge recipe, alarm clock, shaving sequence and the first daily duties.

Chapter 02 · Guests arrive

Chapter 2: The Family Reunion

Route documented

Welcome Aunt Alexandra and Uncle William, complete the garden and floor puzzles, then open Aldous’s secret laboratory behind the painting wall.

01

Receive Alexandra & William

Follow the arrival sequence, collect the family clues and prepare each guest’s place in the estate.

02

Tea service

Use the room clues to assemble the tea service and deliver the correct items before the family gathers.

03

Dining-table toast

Arrange the table, follow the toast sequence and record any optional interactions before advancing the chapter.

04

Flower Pot Mini-Triangle Puzzle

Apply the Mini-Triangle Combination Rule: Bottom-Left + Bottom-Right = Top. Arrange the pink/red buds by height and leaf order on the left, place the white flowers on the right, then follow the small-triangle paths upward until the top target flower is formed. See the full flower and cockroach puzzle solution.

05

Cockroach Grid Puzzle

The wooden boards and stones are fixed, static obstacles. Plan a clear route, then click to guide each cockroach around them and into the top black vent one at a time. Do not try to drag any obstacle.

06

Stove cat & painting passage

Open the stove door and the orange cat walks out on its own; no fire or Matchbox is required. Read the note left by Aldous, then click the specified elements in the wall painting in the clue’s order. The painting opens the concealed entrance. See the Cat / Harvey puzzle guide.

07

Aldous’ Secret Alchemy Lab

Aldous’ Secret Alchemy Lab is directly behind the painting wall—it is not below the estate. Enter through the opened painting and perform the potion preparation there, using the exact in-game symbol reference for every ingredient. Open the complete symbol guide.

Exact visual references

The focused guides use original alchemy-cipher, flower-and-cockroach, stove-cat, and Harvey screenshots; game-specific symbols are never redrawn.

Chapter 03 · Hunt, household duty & cellar

Chapter 3: Attic & The Hunt

Route documented

Search the attic with the Vanderboom family scroll, complete the hunt, serve Alexandra in the bathroom and recover the ancient book from the Lady of the Lake altar.

01

Attic family scroll

Trace the family-history clues on the attic scroll and use the resulting route to locate the hidden objects.

02

The deer hunt

Prepare the hunting sequence, obtain the venison and carry the required items back to the estate.

03

Laundry & young James’s diaper

Complete the laundry sequence and clean young James’s diaper. After cleaning young James’s diaper, go directly to Alexandra’s bathroom; there is no need to search the estate for the guests.

04

Alexandra’s bath

In the bathroom, adjust the water temperature, add soap, comb her hair, then help her change and enter the bath before leaving the room.

05

Three pocket watches

Collect all three pocket watches and use their clues to open the route into the cellar. The watches lead to the cellar shrine—not to Aldous’s laboratory.

06

Cave & Altar of the Lady of the Lake

Enter the cellar and open the Cave & Altar of the Lady of the Lake. Complete the altar sequence to obtain the mysterious ancient book.

Location distinction: the Lady of the Lake cave and altar are in the cellar; Aldous’s Secret Alchemy Lab is behind the wall painting.

Chapter 04 · Poisoned service

Chapter 4: Cooking, Stolen Elixir & Family Gear

Route documented

Prepare the kitchen dishes, survive William’s poisonous mushroom, discover the stolen Elixir and dress the family for the farewell dinner.

Prepare the kitchen dishes

Complete the kitchen preparation for the potatoes, cake and thick soup, keeping each finished dish ready for service.

02

William’s poisonous mushroom

William sneaks into the kitchen and gives the servant a poisonous mushroom. Add it to the soup as the scene requires.

03

Hallucination & collapse

Aldous and the servant taste the soup, become poisoned, hallucinate and collapse unconscious. Continue through the distorted sequence until the servant wakes.

04

The stolen Elixir

After waking, return to Aldous and inspect the room: Aldous discovers that the Elixir has been stolen.

05

Find the family’s dinner gear

Search for every family member’s required clothing and equipment. Check the fifth stair from the bottom for the hunting rifle, locate Aldous’s tie, and deliver the remaining items before dinner begins.

Progress gate: the farewell dinner does not begin until every family member has received the correct clothing or equipment.

Chapter 05 · Finale

Chapter 5: Farewell Dinner & Blood Moon Ending

01

Farewell dinner

Seat the fully prepared family and complete the dinner interactions until Alexandra reveals her plan.

02

Alexandra’s betrayal

Alexandra betrays the family and begins the Blood Moon immortality ritual. Follow the ritual interactions while keeping the route to young James open.

03

Rescue young James

Break away from the ritual, rescue young James and carry the baby out of the estate.

04

Harvey & the Coachman

Leave with Harvey the Parrot and board the waiting Coachman’s carriage outside. The Coachman pulls the carriage curtains closed and drives the servant and baby away from the estate, opening the wider Rusty Lake story.
