American investigator on mobile for one doing wet work? (7)
I believe the answer is:
'one doing wet work?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'american investigator on mobile for' is the wordplay.
'american investigator' becomes 'gman'.
'on' means one lot of letters go next to another.
'mobile' is an anagram indicator.
'for' anagrammed gives 'fro'.
'gman' put after 'fro' is 'FROGMAN'.
Can you help me to learn more?
(Other definitions for frogman that I've seen before include "Underwater swimmer with breathing apparatus" , "Underwater diver" , "Swimmer employed in underwater operations" , "Person who works underwater using a portable air supply" , "He searches lakes and rivers" .)
