So there I was, scampering around Mystery House like a lost puppy. After trying to navigate the woods again, examining several pieces of furniture, and trying to rape Sally a few more times, I found myself in the dining room. I thought I had fully explored the dining room on my first walk through it, but this time I had something new: a lit candle. This turned out to be a bad thing, however, as the game's narrative decided I should trip over the rug, fall, and start a fire. There's only one thing to do in a situation like this: RUN AWAY!
I tried to run away, but the fire got out of control and I died. I tried smothering the fire with my towel, that didn't work either. I tried asking for help, same result. Once the fire starts, I only get one chance to use a command before I get burned to death. Water would probably put out the fire, but I don't have any. I have an empty pitcher though. If only I could figure out how to use that fucking sink in the kitchen...
After reading the instructions again, I notice that one of the sample commands they give is WATER ON, which is apparently what I need to type to turn on the sink. I had completely forgotten about it because it made no sense. It still doesn't. I tried commands like USE SINK and TURN ON SINK before and those are far more intuitive commands. Hell, even SINK ON would be better. In fact, if they hadn't specifically told me that WATER ON was a command I might need, I'd still be stuck right now. Now that the sink is on, I need to get some water. My first instinct is to try FILL PITCHER, but I bet I should use TAKE WATER.
Being right isn't always fulfilling.
With water in hand, I head back to the dining room. This time, it shall be the fire that perishes. Despite my better judgement, I try POUR WATER instead of USE PITCHER. To my surprise, it works. The fire is out and there's a hole in the rug. And if you know anything about video games, then you know it's not just a mere coincidence that the rug caught fire. I am going to find some sort of key item in that hole.
It's a key. See? I told you it would be key. Maybe it opens that damn chest in the attic.
It does! Let's see what I've won...
Sweet, it's a gun! I hereby promise to murder the next living thing that I encounter in this game. Odds are pretty good that the next living thing I encounter will be the murderer anyway, so it all works out. Now I just need to find the murderer. And the jewels. But where the fuck am I supposed to go? Maybe I can do something with that stupid button back in the study. I sure hope I can, I don't want to press my luck by wandering around in the woods. Wait a minute... PRESS. Why the hell didn't I think of that before?
PRESS and PUSH may be basic synonymns, but Mystery House only understands PRESS BUTTON. Pressing the button does exactly what I assumed it would do back when I tried to push it: it opens up a secret passage. And what do we find in secret passages? MORE WITCHES! Sorry, I can only go so long without a Holy Grail reference. I imagine I'll probably find one or more of the following things behind this wall: another dead body, the jewels, the real killer. Let's see how good I am...
I enter the passageway and I discover... absolutely nothing! There's some stairs though. Maybe there's something good at the bottom.
Hey look, it's a completely frivolous screen that shows me walking on the stairs! I have to choose UP or DOWN. Seeing as I just fucking came from upstairs, and seeing as the secret passage closed behind me, I'm gonna go with DOWN. 
I immediately notice two things in this room. First, there's a GIANT FUCKING KEY on the table. Secondly, there's a hole in the wall. Oh, there's a dead body too. It appears to be a guy, which would mean it's Tom, which would mean Daisy is the killer. Just to be sure, let's examine the body closer.
Yup, it's Tom and he's clutching a daisy. I think the Williams put that little clue in there so that this game could be used as a learning tool in special ed classes. It would definitely be a team effort, but a class of retarded kids could probably figure out that Daisy killed the guy holding the daisy. Speaking of which, Daisy could be lurking around here somewhere. While I was busy making easy jokes at the expense of genetically deficient children, she could have snuck up behind me. I'm better get the fuck out of here. First I'm gonna grab the big ass key off the table, then I'm heading through that door on the far wall.
Another hallway and another stairway. The stairs are my only option besides turning around, so...
The stairs lead to a pantry. The pantry doesn't hold any items of use, but it does have a passageway in the form of a hole. I wonder where it leads...
Absolutely nowhere!
With no other options left, I head back to the room where I found Tom's body to see if I can successfully enter the hole in that wall; I can. The hole leads to a tunnel, and the tunnel presumably leads somewhere good. I guess we'll have to wait and see...
