Soothing the Baby
Soothing the Baby wants the champagne given to the infant James before William gets it. Where the bottle is, and why a polite playthrough misses it.

Deep Cleaning
Deep Cleaning is not about the floors. Scrub the family portrait in the kitchen — the clue points at the drawing, not the job you were given.

Close Inspection
Close Inspection is the bathroom keyhole on the second floor. Look through it before you help with the bath — once the scene moves on, the chance is gone.

Petting the Horse
Petting the Horse needs many clicks, including on its glasses, and all of them before the carrot. One click does nothing, which is why it looks broken.

Feeding the Cat
Feeding the Cat is an order problem, not a discovery one. Rustie takes the milk first and the dead mouse second — reverse it and the achievement is gone.

Chasing the Crow
The crow is not at the attic window when you arrive. Move in and out of the containers until it appears, then click it — the clue skips that step.

Five things to know before you start
- 1
The game runs on three in-game days. You cannot skip a day, and most tasks must be done in a fixed order.
- 2
When a scene will not advance, the missing step is almost always an item you have not picked up yet — sweep the room before you re-try the puzzle.
- 3
Hidden achievements are triggered by doing the *wrong* thing deliberately (feeding the goat, failing the exercises). Grab them on your first pass; a second playthrough is not required.
- 4
One three-digit code — the luggage in the garden — is randomised per playthrough. Shake the baby basket and listen; no guide can give you that number.
- 5
The final secret, "You've found him!", only starts after the credits. Do not chase it before you finish Day 3.
Servant of the Lake FAQ
+How long is Servant of the Lake?
It is built as three in-game days. Rusty Lake's premium titles typically run a single evening, and this one is in the same range — most players finish the main route in one sitting. Chasing all 49 Steam achievements adds a second pass.
+Is this walkthrough spoiler-free?
Every page carries a spoiler level in its header — none, light, or heavy. Puzzle pages give you the solution and nothing about the story around it, so you can unstick yourself without reading ahead.
+Do the demo and the Lite version share solutions with the full game?
The demo covers the opening slice of Day 1, so those puzzle solutions carry over exactly. Content past the demo is unique to the paid release.
+Is the walkthrough complete?
Day 1 is documented step by step. Day 2 and Day 3 are complete for every puzzle we could verify against more than one source; anything we could not confirm is labelled "to be confirmed" on the page rather than guessed at.
+Do you cover the rest of the Rusty Lake series?
Not here. This site is Servant of the Lake only — walkthroughs, puzzle solutions, codes and achievements. Which order to play the other eighteen games in, and where this one sits in the timeline, is on our sister site servantofthelake.net.
Wondering where this one sits in the wider Rusty Lake series, or what order to play the other eighteen games in? That is on servantofthelake.net. This site stays on Servant of the Lake.
