Looking for the Alone in the Dark Astronomical Clock puzzle solution? Standing as a centrepiece in the Gallery on the Second Floor, the Astronomical Clock poses a bit of a head-scratcher for sweaty sleuth Carnby. There’s some ground work involved, namely tracking down two Broken Pieces to actually have a go at cracking the clock, then a two stage puzzle to get through.

We’ll walk you through how to find the Alone in the Dark Astronomical Clock puzzle solution. You’ll need both Broken Plates for this one, so check out how to get the first one by solving the Perosi’s Room zodiac sign puzzle.

Where to find the talisman numbers hidden on the Astronomical Clock

After solving the piece puzzle, interact with the clock above. The solution is similar to the first talisman puzzle in Miss Jackson’s seance parlor in the French Quarter in Chapter 1. You’ll see three discs of different sizes. The dial on each one is tuned to a specific number, as follows:

  • Small disc – 3
  • Medium disc – 4 (IV in Roman numerals)
  • Large disc – 6

Jump back to the talisman and adjust the three discs so that the numbers listed on the right match up with these on the clock – 346. Check the image above for the correct arrangement. Solving the puzzle then points you to Jeremy Hartwood’s Room for you to continue your investigation.
