Voodoo kin (5)
I believe the answer is:
obeah
'voodoo kin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for obeah that I've seen before include "spells in Caribbean" , "amulet" , "Caribbean witchcraft" , "that's charming" , "West Indian witchcraft" .)
