What is the climax of the Strange Case of Dr. Jekyll and Mr Hyde?

Answer 1

Concerned for his well-being two of Dr. Jekyl's friends break into his house even against his protests. He is Mr. Hyde at this point and fearing to be found out he drinks poison.

The above answer is not completely correct. the reason they break down the door to Jekyll's cabinet is because they are convinced that Hyde has killed Jekyll and is hiding out in Jekyll's cabinet. The reason Hyde drinks the poison is because he is wanted for murder(murder of Sir Carew). Rather than be disgraced and submit to the ordeal of a trial, which will inevitably end with him being hanged at the gallows, he summons the 'courage' to kill himself.

Answer 2

The climax of "Strange Case of Dr. Jekyll and Mr. Hyde" is when Dr. Jekyll's experiments with his alter ego, Mr. Hyde, spiral out of control, leading to Mr. Hyde taking over more and more frequently until Dr. Jekyll ultimately loses control over his transformations and is consumed by his darker side.

Answer 3

With Mr. Hyde drinking poison. True but the novels true end is with the end of Dr jekyll i.e. when Mr Utterson finishes reading Dr jekyll's fate.
