Why can't I add an override attribute access element?

Question

In the base class, I have this property:

public virtual string Text 
{
    get { return text; }
}

I want to override this and return another text, but I would also like to be able to set the text, so I did this:

public override string Text
{
    get { return differentText; }
    set { differentText = value; }
}

This, however, does not work. I get a red squiggly under set, saying that I cannot override because it does not have an access set. Why is this a problem? What should I do?
