One theme in the strange case of dr. jekyll and mr. hyde is "it is important to trust one’s instinct.” which line from the book best supports this theme? “you have not forgot, sir, that at the time of the murder he had still the key with him? ” “this is beyond me, poole,” said the lawyer. “let us go back to the cabinet.” “i’m book-learned enough for that; but a man has his feelings, and i give you my bible-word it was mr. hyde! ” “that is the same drug that i was always bringing him,” said poole.
