This is rather a difficult puzzle, though, as the Professor remarked when
Hawkhurst hit on the solution, it is "just one of those puzzles that a
person might solve at a glance" by pure luck. Yet when the solution, with
its pretty, symmetrical arrangement, is seen, it looks ridiculously
simple.
It will be found that Romeo reaches Juliet's balcony after visiting every
house once and only once, and making fourteen turnings, not counting the
turn he makes at starting. These are the fewest turnings possible, and
the problem can only be solved by the route shown or its reversal.
