Look at the piano; neat little scene occurs here. Look at it again; now it's a puzzle(with a bad pun..."STAUFWAY?")
Here, you're supposed to play "Simon," basically, and eventually repeat 18 notes. Hope you're a musician. If you are, here's the solution in musical form, low B (the octave Stauf plays it on), then upper B, down to F#, up to G, down to E, down to D#, up to E, up to F#, back down to E, down to low B, up to high B, up to C, down to high B, down to A, down to G, down to F#, down to E, and back up to F#. That's it for that one.

Then you get a wonderful scene with Dutton, Tad, Martine, Edward...oh, boy. As a matter of fact, here's where Dutton gets killed...by Edward. Things get really weird now. Go over to the potted plant and click on it; you'll wind up "climbing" it, back into Dutton's room. So now, leave and go into the doorway across the hall to the right. You're in the bathroom. Amazing! Just likein Dark Seed, there's no toilet in the bathroom! Oh well.

Jan, UHS hints might help also.
