A few ghosts in the nearby town refuse to leave the houses they're haunting. They'd terrorized the owners until they left, which is fine, but the ghosts need to move on.
Help six ghosts who are haunting 6 houses with their unfinished business and they will give you the 6 pieces of the plate in return.
Enter the following house ...

... and you will find the first ghost who can't leave. Her loved ones are still the suspects of her murder, too. The objects found in the house belong to them - her brother's rope πΏ, her husband's shirt π, her sister's comb π, her dad's amphora πΊ and her neighbour's axe βοΈ.

Then enter the Prison and bring the info from the deceased to the guard. Then drag the numbered stones to the suspects based on the numbers next to the objects. That's how they'll know what belongs to whom and who was the killer.

Then return to the house and get the piece of plate.
Enter the following house:

The second ghost hasn't solved the math equations yet. Please figure this out for him and get the piece of plate.

Enter the following house:

Then, return to the first house with the letters and get the piece of plate:
