There's something sticky about crime (5)
I believe the answer is:
resin
'there's something sticky' is the definition.
I can't tell whether this defines the answer.
'about crime' is the wordplay.
'about' becomes 're' (regarding).
'crime' becomes 'sin' ().
're'+'sin'='RESIN'
Can you help me to learn more?
(Other definitions for resin that I've seen before include "Sticky tree exudation" , "Sticky stuff for siren" , "stuff that's sticky" , "Viscous fluid from tree sap" , "varnish, perhaps" .)
