Read the passage from The Strange Case of Dr. Jekyll and Mr. Hyde.

On his way out, the lawyer stopped and had a word or two with Poole. "By the bye,” said he, "there was a letter handed in to-day: what was the messenger like?” But Poole was positive nothing had come except by post; "and only circulars by that,” he added.

Based on the passage, which is the best inference?

Poole dislikes his employer, Mr. Jekyll.
Poole distrusts the lawyer, Mr. Utterson.
Mr. Utterson suspects that Hyde delivered the letter.
Mr. Utterson does not expect Poole’s response
