Snooping at the Library

Marcus:          I'm looking for a book about a detective who solves mysteries.

Librarian:       Could you be more specific, please?  There are all kinds of detectives.

Marcus:           I want to read about dog detectives.

Librarian:        Are you sure dogs can be detectives?

Marcus:           Yes, I'm positive.  I once read about a dog who finds lost people by sniffing.  She solves each case with her nose!

Librarian:        Ah- I know the perfect book for you.   Someone checked it out, but it will be returned very soon.  I'm sure that it will definitely be here next week.

Marcus:           Great!

Librarian:        I'll ask my assistant to save the book for you.

Marcus:           Thanks a lot.
