Puzzle consists of a number of rows of cells having the following form:-
FLIER T TRIFLE E FERTILE
It is easy to see that the second word is an anagram of the first word plus the first single letter. Similarly, the third word is
an anagram of the second word plus the second single letter. When a number of such lines are collected together into a puzzle,
the single letters combine to form two vertical Anchor
words which are normally related by a common theme.
