Longed to bamboozle the CID (6)
I believe the answer is:
itched
'longed' is the definition.
(I've seen this before)
'bamboozle the cid' is the wordplay.
'bamboozle' indicates an anagram.
'the'+'cid'='thecid'
'thecid' with letters rearranged gives 'ITCHED'.
'to' is the link.
(Other definitions for itched that I've seen before include "Longed (to do something)" , "Was in need of a scratch" , "Felt tingling sensation in skin" , "Felt a strong desire" , "irritated!" .)
