18d - Way out in Asia, stay good at heart (3)
I have the answer which, I think, means "way in Asia" thus making "out" an extra word. However, to get to the answer I need the "heart" of two words in the clue, but the second of those two words has 2 letters in the middle, which is one too many, meaning it contains an extra letter - obviously they can't both be right and I've now reached the going round in circles stage, so any help would be most appreciated.
