The Servant of the Lake demo follows a new servant arriving at the Vanderboom estate. It is short, but it already has the kind of strange item combinations and unsettling humor Rusty Lake players expect. This walkthrough covers the complete Steam demo and ends when the guests arrive. It does not reveal puzzles from the full game.
Enter the Vanderboom Estate
Open the curtains inside the coach. When it stops, get out. Take the carrot from the planter and feed it to the horse. Open the nearby window and take the tin cup. Walk left, speak to the coachman, then open the small compartment under the coach to get a second cup.
Go to the window on the right side. Place both cups with the three already there. Arrange all five cups by the number of stripes, from one stripe to five. Take the coin from the first cup, give it to the coachman, and pick up the iron bar after he leaves.
Use the iron bar on the loose board near the planter. Move the board until it comes free, take the key, and unlock the front door.

Sign the Contract
Speak to the maid and take the crow feather. At the table, dip the feather into the ink and sign the contract. Speak to the maid again. Your first job is to prepare breakfast for Mr. Aldous.
Find the Breakfast Ingredients
Three portraits give you the code for a locked box. Tap Aldous Vanderboom's portrait and watch him shake his watch three times. Go through the center door and tap Alexandra Vanderboom's portrait; she raises two fingers. Upstairs, William Vanderboom blinks five times. The code is 235.
Continue to the room where the maid is waiting and take the bottle of milk from the box. Go up the stairs on the right, take the small pot, and open the lower cabinet. Enter 235 on the locked box and take the sugar.
Tap the low hole in the wall and take the dead mouse. Give it to the cat in the earlier room. The cat leaves behind a box of matches.
Return to the entrance and go through the left door. Take the wood and the bowl of oats. Put the wood in the stove, light it with the matches, and close the stove door. Place the pot on top, then add the milk, oats, and sugar. Take the pot of porridge.

Wake Aldous at 7:00
Return to the room where you found the mouse. The door to Aldous' room is now open. Pick up the slipper. Open the puzzle box beside it by rotating the patterned tiles until each tile matches the pattern shown below it. Take the razor.
Take the bowl from the table and read the morning routine. Open the bed curtains, but do not worry when Aldous stays asleep. Open the bottom two drawers on the left to get a spoon and the second slipper.
Remove the hand from the toy soldier. Tap the soldier and remember its movement: left, right, down, right, right, down. Place the hand on the alarm clock. Set the small hand to VII and the large hand to XII, which gives you 7:00. Put both slippers on Aldous after he wakes.
Shave Aldous and Finish the Porridge
Move the clothes on the right side of the room and take the cloth hidden behind them. Use the razor on every small hair on Aldous' face. The final cut removes his earlobe. Take it, then use the cloth to clean the blood.
Give Aldous the bowl and spoon, then pour in the porridge. He says something is missing. Open the window, feed the earlobe to the bird, and take the key it gives you. Use the key on the top drawer and collect the berries.
Add the berries to the porridge. A bug begins moving between the holes in the bowl. Move a berry away, watch where the bug goes, and cover that hole with another berry. Repeat until the bug is trapped and crushed. Bring the spoon to Aldous' mouth several times until he stops eating.
Exercise, Clothes, and the End of the Demo
For Aldous' exercise, repeat the toy soldier sequence: left, right, down, right, right, down. Dress him in the correct order: shirt first, vest second, and bow last.
Look through the window. A carriage is bringing the guests to the estate. Tap the carriage to finish the demo.
