I know that some people at rpc do not like Araucaria. Today's preamble
probably won't change their minds.
"The puzzle is in part an alphabetical jigsaw where the solutions are
all of a kind. These are to be entered in the unclued spaces in the
diagram, wherever they will go, unless they appear hidden in other
solutions. Their clues usually have no further definition, may be
somewhat “left field” and often relate to sound without any indication
such as “they say”. All other clues are normal."
