Atomfall‘s 1950’s alternate-history surroundings will provide you with plenty of harrowing and distressful moments, but one of the best (worst) is that of the Prudence Hook, and how to get into her conservatory. Thankfully, we’ve given you the rundown below on how to get it easily and quickly, without ever leaving the room.
How to Get the Conservatory Key

How to get the Conservatory key could not be simpler in Atomfall. Go to Datlow Hall, speak to Prudence Hook, and go through the dialogue until she mentions asking Jenks if we need anything. Now, you need to follow these exact dialogue options:
- “Why can’t I go into the conservatory?”
- “You can trust me…”
- “The guests are already here…”
If you choose any other options, you’ll end up being given a lead to go find the absentee guest Jenks, which delays the inevitable anyway. Once given the key by Prudence Hook, head over to the Conservatory to continue the story. There you have it, by far the quickest way to find the Conservatory Key, and you didn’t even have to leave the room.
If you fail to follow the above conversational prompts, you’ll have to go and find Jenks, the absentee butler of Prudence Hook, and it’s significantly more work. Head over to the Casterfell Dam at 20.9E, 90.9N, and head behind the facility of the dam (20.2E, 90.4N) to find him in all his glory – unfortunately, he’s dead. Loot the body and take the note on it to Prudence, back at Datlow Hall, who will then consequently give you the Conservatory Key.
Once you’ve headed into the Conservatory using the key, you’ll find Prudence’s sister Charity, also long dead. You can go back and tell Prudence of this if you so wish, or ignore her completely, but if you do, prepare for a monumentally heartbreaking moment.
