Andersen's countrymen (5)
I believe the answer is:
danes
'andersen's countrymen' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for danes that I've seen before include "people in Copenhagen" , "Sedan (anag.)" , "Scandinavians" , "Natives of, eg, Copenhagen" , "E.g. Hamlet and Canute" .)
