British bird admits reading abridged version of Hamlet to an islander living in a place known for its disappearances (8)
I believe the answer is:
bermudan
'british' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bermudan that I've seen before include "Pour out copiously" , "Coming from an island" .)
