Unlikely of thief to pocket whisky and cream (3-5)
I believe the answer is:
off-white
'cream' is the definition.
(I've seen this before)
'unlikely of thief to pocket whisky' is the subsidiary indication.
'unlikely' indicates anagramming the letters.
'to pocket' indicates putting letters inside.
'whisky' becomes 'w' (phonetic alphabet: alpha, bravo, charlie etc.).
'of'+'thief'='ofthief'
'ofthief' with letters rearranged gives 'offhite'.
'offhite' placed around 'w' is 'offwhite'.
'and' is the link.
(Other definitions for off-white that I've seen before include "something like cream" , "Colour such as cream or bone" , "Very pale tint" , "Slightly-tinted colour" , "Very slightly yellowish or grey" .)
