*) piano puzzle -- magic mechanism
*) re-assembling torn letter -- really a jigsaw puzzle, but a fair abstraction
   of the problem
*) wine bottles -- magic mechanism

*) hide in the closet at Reid's house -- easy
*) jump into the trolley -- easy
*) get key from pocket at hotel -- easy
*) cut wires of bomb -- slightly difficult, since you also have to cut them at
   the right spot

*) professor's quiz -- requires untaught (by game) real world knowledge; but
   there is an alternate solution if you fail

*) get archive key from librarian by calling her away -- not really difficult,
   but nicely lateral
