Gangsters wasted dosh and got nothing (5)
I believe the answer is:
hoods
'gangsters' is the definition.
(I've seen this before)
'wasted dosh and got nothing' is the wordplay.
I cannot really see how this works, but
'nothing' could be 'o' (looks like zero - 0) and 'o' is found in the answer.
an anagram of 'dosh' is 'hods' which is located in the left over letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hoods that I've seen before include "They hide the head" , "US districts" , "gangsters" , "Headgear < for criminals" .)
