Tortuga's country (5)
I believe the answer is:
haiti
'tortuga's country' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for haiti that I've seen before include "Caribbean country, capital Port-au-Prince" , "Republic on island" , "foreign state" , "West Indian republic" , "W. Indies republic on Hispaniola" .)
