Catwalk is home to a fugitive (7)
I believe the answer is:
runaway
'fugitive' is the definition.
(I know that fugitive can be written as runaway)
'catwalk is home to a' is the wordplay.
I cannot quite understand how this works, but
'a' is within the answer.
The remaining letters 'runway' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for runaway that I've seen before include "One who flies" , "Del Shannon hit" , "Fugitive" , "refugee?" , "One who has taken flight" .)
