Hi! I would like some help with the following trivia questions:

Lucy told Ethel and Caroline Appleby that two actors were at the pool. Who were they?

and

What was Lucy doing with her mother when Ricky left for their anniversary party at the Mocambo?

hope you all can help. thanks in advance.

I think Lucy and her mother were playing cards but I don't know who the actors by the pool were, sorry.
