Is it inappropriate to leave my boss a letter of resignation without informing her face-to-face?

I’ve a bit of a problem. I just found a new job, and they rushed the interview and hire so that I could get my two weeks notice in as soon as possible at my current job. The problem is, I don't work with my boss again for the rest of the week, so I won't have an opportunity to speak to her face-to-face. I want to be able to talk to her, but obviously that is going to be hard to do. Should I call her? Should I go in when I know she’s working? Is that appropriate to come in when I am not scheduled and ask to talk to her? Or can I leave her a letter of resignation, then speak to her later when we work together? I just don't know what to do.

Answer:
If nothing else a call is usual coutesy. Future employers will likely contact this person about you. Best not to burn bridges.

Answer:
Call her as soon as possible. Or schedule an appointment. If all of her times are booked try talking to her secretary and see if they have the ability to squeeze you in if it's very important. However when you do it make sure you accentuate that you really enjoyed working with her and all that. It sucks to have your employees quit.

Answer:
I would advocate talking face to face in order to answer some questions she might have, and to keep a relationship going in case the new job doesn't work out. I suggest giving her a call and scheduling a meething with her.
