The landlady went to the kitchen to find one of her tools
you should drink your tea.look it is good, i'm drinking all of mine
I'm ok, I don't feel so good.
As the landlady was gone Billy began to get suspicious of the tea because it tasted bitter and the landlady seemed to enjoy her tea.
I'm going to get some tools from downstairs to make you feel better
While the landlady was gone Billy switched the tea just in case she poisoned him.
The landlady tried to get Billy to drink the tea by drinking all of her tea. but Billy didn't feel good so the landlady took him to his room.
The landlady brought a scalpel but she forgot her other tools so she went downtstairs to get them.
As the landlady was about to take her first step the poison from her drink kicked in and she began to get dizzy. The landlady missed a step and tumbled down the stairs and landed on her scalpel while Billy died in his room due to the poison he drank earlier.
