Black lace wrapped around telegram (5)
I believe the answer is:
cable
'telegram' is the definition.
(cable is a kind of telegram)
'black lace wrapped around' is the wordplay.
'black' becomes 'b' (as in pencil classifications).
'wrapped around' is an anagram indicator.
'b'+'lace'='blace'
'blace' with letters rearranged gives 'CABLE'.
(Other definitions for cable that I've seen before include "Communication - wire - 200 yards in length" , "This may pull car up" , "Liberal Democrat" , "Naut. length; transmit" , "Heavy chain or rope" .)
