Dances with suspicious bachelors (6)
I believe the answer is:
rumbas
'dances' is the definition.
(rumba is a kind of dance)
'with suspicious bachelors' is the wordplay.
'with' is a charade indicator (letters next to each other).
'suspicious' becomes 'rum' (rum can mean strange or dubious).
'bachelors' becomes 'bas' (I can't justify this - if you can you should give a lot more credence to this answer).
'rum'+'bas' is 'RUMBAS'.
Can you help me to learn more?
(Other definitions for rumbas that I've seen before include "Cuban folk dances" , "Afro-Cuban dances" .)
