One involved in a plot to ruin Tiger fans (9)
I believe the answer is:
intriguer
'one involved in a plot' is the definition.
I can't tell whether this defines the answer.
'ruin tiger fans' is the wordplay.
'fans' indicates an anagram (I've seen 'fanned' mean this (I've seen this in other clues)).
'ruin'+'tiger'='ruintiger'
'ruintiger' is an anagram of 'INTRIGUER'.
'to' is the link.
Can you help me to learn more?
(Other definitions for intriguer that I've seen before include "Person arousing curiosity" , "conspirator?" , "Machiavellian" , "Fascinating" , "plotter" .)
