Fantastic one shot adventure. Great humour with a dash of tense combat and a bit of dark mystery. A particularly good bit with the telescope had the whole group laughing to tears. There is still pleanty of challenge to it as well. One fight was down to the wire due to some hot DM dice. As a DM the adventure was simple enough that at one read I could run it smoothly which is perfect for a quick prep 'I need an adventure for tonight' game. My group was down a player for our normal game so I ran it for three level four characters and play time was just over three and a half hours. All my players said they really enjoyed it and told me to make sure I gave it 5 out of 5 stars. For the price, I would strongly recommend picking up Into Ivy Mansion if you need a quick prep game for right now, or to keep in your DM pocket.
[5 of 5 Stars!]
