Kate's Brother Hunt (You've Found Him)
Player-documented guide. Rusty Lake does not publish official puzzle solutions, and this post-credits route is written from player playthroughs. Treat every step, code, and alignment as community-reported and confirm it in your own game.
After the Sunday evening credits roll, Servant of the Lake allows free-roaming exploration of the Vanderboom estate to resolve lingering notebook mysteries. The most substantial post-game questline is finding Kate's lost brother, which awards the hidden achievement You've Found Him. The sequence decrypts correspondence, aligns clock hands, follows an exact tile path, charts attic constellations, and cracks the cellar bottle puzzle.
Step 1: Discovering Kate's Letters
Begin in the ground-floor servant quarters and examine the locked desk drawers beside Kate's cot. Retrieve the Crumpled Note from the coat pocket hanging near the washbasin. The note gives the first family-schedule clue with a time reference: "Meet me when the mantel piece strikes four past five."
Step 2: The Mantel Clock (4:05)
In the main parlor, interact with the ornate gold pendulum clock. Turn the hour hand to IV (4) and the minute hand to I (5 past) to set 4:05. The bottom compartment drops open, revealing Kate's Second Letter and a small Brass Key.
Step 3: The Bathroom Wall Tile Sequence
Go upstairs to the guest bathroom. Use the Brass Key to open the medicine cabinet and retrieve the Tile Grid Sketch. Inspect the mosaic tile wall above the bathtub and press the alternating dark and light tiles in the directional sequence from the sketch: RRRLRLRRL (Right, Right, Right, Left, Right, Left, Right, Right, Left). A secret brick shifts, granting the Star Dial Lens.
Step 4: Attic Constellations and Poem Statues
Climb to the attic via the pull-down hatch in the upper hallway. Mount the Star Dial Lens on the brass telescope aimed through the round skylight and rotate the rings to match the constellations referenced by the three poem statues: The Crow aligns stars 3 and 7; The Stag aligns stars 1, 4, and 9; The Fish aligns stars 2, 5, and 8. Completing the alignment reveals a hidden symbol chart on the wooden roof beam.
Step 5: Cellar Bottle Cipher and Code 6294
Descend to the wine cellar beneath the kitchen trapdoor. Examine the bottle rack along the back stone wall and rearrange the labeled vintage bottles so their neck insignias match the symbol chart from the attic. Reading the vintage years of the correctly placed bottles yields the four-digit keypad code: 6294. Enter 6294 on the heavy iron lockbox behind the wine barrels.
Step 6: The Secret Chamber and Achievement Unlock
Open the iron safe to obtain the Underground Passage Key, unlock the red-cloth doorway at the far corner of the cellar cave, and walk to the end of the passage to uncover Kate's brother's hidden retreat and trigger the dialogue sequence. The achievement You've Found Him unlocks immediately after the conversation.
FAQ
Can I complete this guide before finishing the main story? No. Certain rooms, including the attic telescope alignment and cellar passage, only fully open after the Sunday credits roll.
What if the clock at 4:05 does not trigger? Ensure both hands click into their exact notches; listen for a mechanical gear click when the minute hand hits the 1 (5 minutes) mark.
Does code 6294 change between playthroughs? Players report that 6294 is fixed across platforms and versions.
