The men can be brought back in fetters (8)
I believe the answer is:
manacles
'fetters' is the definition.
(manacling is a kind of fettering)
'the men can be brought back' is the wordplay.
'the men' becomes 'sel' (I can't justify this - if you can you should believe this answer much more).
'be' becomes 'am'.
'brought back' is a reversal indicator.
'sel'+'can'+'am'='selcanam'
'selcanam' written backwards gives 'MANACLES'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for manacles that I've seen before include "Fetters for the hands" , "Handcuffs" , "chains" , "Shackles for the wrist" .)
