Talk to Jerico, who is in the building south of the Ardougne north bank.
Search the cupboard near Jerico for some bird feed.
Go behind Jerico's house and pick up a pigeon cage.

Take the rotten apple on the east side of the house.
Squeeze through a gap directly east of the rotten apple, along the west side of the metal fence.
Use the rotten apple on the cauldron in front of you.
Go back through the fence and attempt to go into the house, a mourner will stop you.

Without teleporting, go to bank and deposit your plague sample. Teleporting with the Plague Sample in your inventory will destroy it, forcing you to retrieve another sample from Elena.
Retrieve the plague sample from the closest bank to Rimmington and walk there. (Skills Necklace teleport to the Crafting Guild is the quickest.)
Enter the western most house in Rimmington and talk to the Chemist. (Do not mention that you have the sample or he will take it away from you and you will be forced to go back to Elena to get a new one) ( 3•2•2)…
