Word Square

a cryptic puzzle by Emily Cox and Henry Rathvon

Solution
This puzzle is a double-layered affair. The outer portion of the diagram contains words clued and entered normally. The inner portion is a word square, in which the five Across entries are the same as the five Downs. Cryptic clues to these five words (listed a-e in no special order) are formed by designated entries from the outer diagram. In all, answers include four proper nouns.
