One evening, Poole visits Utterson and asks him to come with him to Jekyll's house. They go to the laboratory but find the door locked. Inside they can hear a voice, and both are convinced it is Hyde.
Poole explains that Jekyll has been asking for a particular chemical for days now but every time it has been fetched for him he rejects it as
not pure. Poole also explains that he caught a glimpse of the man inside and he looked barely human.
Utterson decides to break down the door and inside they find the body of a small, deformed man, who Utterson recognises as Hyde, on the floor wearing clothes that would fit Dr Jekyll. He is twitching and holding a vial.
On the desk they find a confession written by Jekyll and a copy of his will with Hyde's name crossed out and replaced with Utterson's. These documents are taken by Utterson to study. He tells Poole that he will return before midnight once he has read them.
