Multi sure likes thieves
Kaito kid would be proud
The only thing we know about the doors' mechanism is that using a keycard on the sensor unlocks both doors.
But does it work the same way when locking, I wonder? The story never specified if both doors lock when using a single sensor.
So I suggest that to lock both doors you need to use the card on each door's sensor.
This means anyone could have accessed the room upon Heron locking the door behind the detectives, because the backdoor was unlocked.
Heron forgot to lock that door at this point.
During the chase, Sparrow had no other option but to use one of the guest doors. But let's not forget she works there and had likely surveyed the entire building before sending her letter.
While investigating she found a door that led directly to the back of the hotel. The hotel is strangely structured, like our protagonist said at the beginning, so it is possible a door leading directly outside exists on a second or even third floor. Let's call it an artistic choice.
To further support this theory, note the room number is 102. If we assign numbers from 0 to 2 to the first three letters of the alphabet and put the letters in 102, we get BAC. Back. Back door!
This means that, to the protagonists, Sparrow seemingly ran into one of the rooms. But she actually fell outside. The door was locked because it either had an autolock (like hotel rooms should have) or she managed to hold on to the door long enough to lock the deadbolt.
Now outside, Sparrow tried the door to the gallery and found it unlocked. Immediately upon entering, she spotted Heron still doing whatever she was doing. Sparrow struck from behind and killed her.
Our culprit looted the corpse, found the keycard, and immediately thought of a plan.
Before anything, she stole the painting. The worst thing that could happen was being caught in the middle of setting up the scene and having to bounce without the painting.
After this, she put the key card on the corpse's hand and closed it. When rigor mortis appeared around 2 or 3 hours later, the hand would remain closed and would not let go of the card.
Once rigor mortis had set in, Sparrow used the ladder to reach the chandelier. Let's ignore how exactly she did the following, maybe she jumped over to it or something, but she managed to tie a rope to the chandelier, and then tied the end to the top of the back door's stairs.
That done, the corpse was brought up the stairs. Sparrow untied the rope and tied it around poor (dead) Heron's neck. She screamed super loud so people would come to the gallery and opened the door leading to the back.
What followed were three actions that had to be done in quick succession:
Sparrow brought the victim's hand to the sensor (remember it held the keycard), pushed it off the stairs as she herself jumped out the hotel before the door closed.
The thief then got away with the painting.
Due to the abuse the poor chandelier was subjected to, it ended up falling when the detectives got to the body. F chandelier.
This has not been challenged (publicly) for so, so long, that when I tried to reply, the site asked if I was sure I wanted to bump the thread and suggested I create another instead. But worry not, I have come to end your suffering!
You may not know this, but I am a spreedsheeter at heart. Since this gameboard is not very different from a
Liar's Paradox(Knights and Knaves? I don't know the name exactly, it was a riddle about prisoners), making a spreadsheet for it was very possible.
I had fun creating it
if you ignore my frustration due to my shitty laptop pad that moves the cursor wherever the hell it wants along with the three hours it took me to create it because this is way more complex than the prisoner riddle.
The most fun was testing each possibility, which didn't take long. Probably half an hour or so. Maybe one hour too.
I'm not going to go over the many possibilities I tried until I reached the solution. I will just say it outright (who the killers are, who they killed, and why they can only kill that specific person).
The killers are Alina, Ana, Justin, and Yael.
Each killer must kill only once.
In order to know exactly which killer murdered which victim, we must first take a look at the final murder. Everyone known to be alive is cleared from the crime, so the only suspects are the three who are "dead."
Ana in particular has an alibi for all murders up until her "death." Due to a lack of any alibi after that, her only possible targets are Augy and Julia. Katie, an innocent, confirmed that Ana herself could not have killed Augy. This means her only possible target is Julia.
To know Augy's killer, let it be known two innocents (Katie and Toddy) confirm that none of the dead people could have killed him. The only killer alive (and with no alibi) is Julian, so we can blame him for Augy's murder.
The only ones who could have killed Sophia are Aline and Justin. Since Justin's already got a target, Aline got Sophia all to herself.
By process of elimination, Yael is the last and only killer who can kill Gabriel, the leftover victim.
I am now required to describe how the four did it:
Alina first killed Sophia and hid her in the closet. Before the body was discovered, Ana helped Alaina get her clothes all bloody so she could fake her death. After Sophia was found, Ana brought all attention to her location (and thus Alaina was found). Yael lied about Alina being dead.
Yael followed Gabriel upstairs to "find more food." The two were alone. Yael had more than enough time to kill him and feign death, same death which Ana, also a culprit, "confirmed."
Luckily for Justin, most clicker games have upgrades which automatically click for you. He got those and left to kill poor sad Augy. Ana, the second "victim", faked her death. Justin covered for her.
Lastly, Ana either hid inside the room the group picked beforehand or Justin happened to be the only person facing the door and didn't say anything when Ana walked in and out. Either option ends with Julia dead and all purples holding true.
