After Sally’s attorney has filed the answer to the complaint, Brenda instructs Frank to have a private detective assigned to case. Frank hires “Pink Pete’s Licensed Investigative Services, Inc.” Pete is paid to strike up a conversation with Sally at a local bar without letting her know that he has been hired by Forthright’s firm. Sally consumes a large amount of alcohol, complements of Pete’s expense account, and admits that the defamatory statements were untrue and completely unfounded.

B. No, because Pete was a licensed investigator.

C. Yes, because Pete took advantage of Sally while under the influence of alcohol.
