Outlined - Enough?

The outline I have for my modern day ghost story, tentatively entitled Closes at Dusk, looks almost finished enough to begin. It's 33 chapters, and except for the details of the resolution it's pretty specific as to events - i.e. I know in a very general way what needs to be done for the ghost to go away, but I'm a little hazy on how exactly those realizations will come about, in a way that is satisfying and not contrived, poignant and not sentimental.
