The Last Door - Chapter 4 Walkthrough

The Last Door, Chapter 4, Ancient Shadows is a point and click horror game from The Game Kitchen, an indie company who brought this game to life through donations and kickstarter, and what a game it is. Ancient Shadows follows on from Chapter 3, the Four Witnesses, after the drama-tic (hah) events of the last chapter we find Devitt travelling to visit his old friend Alexandre in his home in the countryside. What could go wrong.

If you've come too far then you can find your way back to the walkthroughs for Chapter 3 here, Chapter 2 here, or Chapter 1 here.

Now that that's out the way, let's get on with the final segment of The Last Door, Season 1.

Chapter 4, Ancient Shadows

Hints without spoilers:

I don't know how to develop the envelope: There are instructions in the room on what order to do things, you'll also need a red bulb and cannot do it in darkness or white light. You'll need a way of tinting the pre-existing one, not fixing the shards on the floor.

I don't know how to work out the clock puzzles: Read the notes around the house that relate to the clock and make sure to work out the time difference between the upstairs and downstairs clock. The upstairs one needs to read the time mentioned in the notes but only the grandfather clock can be changed.

I have a blue crystal thing, now what: Look around the house, inside and out, until you notice something different in somewhere you've been before. Follow the signs from there.

What do I do with the telescope: Have a good look through it and check in your inventory to see what the view may resemble then, looking through the telescope again, click the areas that are highlighted in the item you have.

What are the strange symbols for: The three important ones unlock a puzzle in the same room you're in, look around the room then match up the symbols with the positioning of the locks.
