Have you read any Agatha Christie novels? I really enjoy reading her mysteries.
Yes I have read The Mousetrap before
Oh, that is a classic. I think it was made into a play, in London and ran for a long time. 
Yeah I think they may have made it into a movie too. I know some of her books have become movies.
Yes. It has a surprise ending, and theaters goers where told not to tell anyone. I think it ran for more than 50 years.
A Dose of Romance was also a book by her. I'm a big fan of that one.
I don't remember that one. What is it about? Was it popular?
Basically a man is about to get married and then finds a new girl who he considers to be his soulmate.
Oh, that would complicate matters a lot. Does he end up getting married or not?
He does end up getting married, to the new soulmate.
Well, at least it had a happy ending.
