Saz,
A very tenuous link. At the time I wrote the Shurugeon walk-through I was re-reading Alistair's McLean's "Where Eagles Dare." At one point in the book the heroes are crouching in the castle's Musician's Balcony watching the proceedings below in the hall (where the actor posing as the general is about to be injected with truth serum).
Obviously my "linkages" need heavy-duty maintenance.
