First Floor
The level starts out simply enough, with a couple guards having a conversation. A second floor balcony provides a relatively easy way into the house. I get in and go to the ground floor. My usual way of looting is to take things level by level, so I explore the entire first floor initially. The front of the house is challenging mostly because of the flooring. Lots and lots of tile. Some carpeting to muffle sound, but plenty of noisy surfaces to navigate. The rooms are more or less laid out reasonably. Sitting rooms, dining rooms, a kitchen. The first floor garden is normal enough, though as you get further back the stream that wanders through the house/grounds and the maze like areas further back (with a single glowing mushroom whose light you can extinguish) starts to support the description of Constantine as "eccentric". There are a couple of locked doors, one of which is in a stairwell that leads downward from the first floor and can't be opened at all. The other is in the garden area.
Second Floor
Things start to get a little stranger here. Several traps exist, and the face motif is established. Lots of the stonework has a face carved into it, and I have to admit the first time I opened the door to reveal a big stone face behind it startled me a bit. I'm sure I was killed by several of the traps the first time through, until I learned to look out for the faces with their mouths open, and to approach things from the side instead of head on. Bedrooms up here mostly, with loot and a key. The key is near a note explaining that an gardener didn't know not to enter into the locked area in the garden, so I can go down there quickly and get some more loot, and the incriminating evidence on Constantine. Which apparently is that he pays his bills with raw gold. Not entirely sure why that is incriminating, but it is evocative and is laying the groundwork for Constantine being a man very interested in nature, along with all the gardens & plants present in his house. While I'm back down in the garden, it's time for a visit to the very whimsical area accessed via the tongue of yet another face sculpture.
Upper section and the Sword
Here we really get into the WTF portion. Upside down and sideways rooms, dirt and plant filled corridors that lead off from built areas that you know are on the upper floors of a mansion, but are also somehow underground? Did we pass through some kind of portal to another realm? Certainly the normal rules don't apply. This area is truly a maze, but keep going upwards and you'll eventually get to the Sword (surrounded by tiled floors and bright lights, hope you kept some water arrows and moss arrows handy). Parts that stick out to me from this section: The door that opens to a corridor floating in blackness, the perspective area where all the doors but one are too small for you to go through, the area where the corridor rotates around 360 degrees. And of course the floating Sword. We've seen magic already in the world of Thief in small amounts, traps mostly, but here we get a big glimpse into the fact that things are more complicated than they seem, and that Constantine is in some way very powerful. So get the sword and get out.
Intermission
Then we get a nice little movie. This one is a bit animated, unlike the other sketched cutscenes, and is a bit longer. Victoria tells Garrett it's time for him to receive his payment. And so we meet Constantine, and the story, such as it is, really gets started. The preceeding missions are a clever mix of introducing you to the world, getting you used to the tools and the game flow, and just plain entertaining and fun to play through (with the possible exception of the Thieves' Guild). So now you are truly Garrett, master thief, and you will need your skills going forward. One flaw that Garrett has is that he is blinded by his greed, so Constantine's mention of 100,000 is large enough that Garrett doesn't ask any more questions, though he really should. Like how long has Constantine been watching him, what is the relationship between Victoria and Constantine, why is this gem worth so very much money to Constantine? Garrett also doesn't notice the brandy drops sprouting plants after they spill. On the wood maybe, restoring the dead wood to life? The brandy does have "restorative properties" so I assume it's very similar to the healing potions Garrett has had access to for the entire game so far. Anyway, given that the takes from his previous jobs are all under 3,000, 100,000 is a very large sum indeed, so Garrett accepts the job. It's time to get the Eye.
