the books your thinking of were The Nancy Drew & Hardy Boys Super Mysteries Series. I will stick to my classics, but interesting theory. However Nancy with anyone but Ned just can't see it...:)
i think frank is nice but i like ned better hes loyal cares for nancy would do anything for her sometime i think yes she should marry ned there perfect for each other if she married frank well lets just say it wouldn't work out there relationship would be boring with nancy and ned they are two very sweet people so NANCY AND NED FOREVER THEY ROCK!
Its time for her to say, "its over."
