Leo gets fungal problem in August and curses it (4,8)
I believe the answer is:
'leo' is the definition.
(I know that loss adjuster is a type of private investigator)
'fungal problem in august and curses it' is the wordplay.
I cannot quite understand how this works, but
'it' could be 'sa' (old-fashioned abbreviation for sex appeal) and 'sa' is located in the answer.
This explanation may well be incorrect...
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for loss adjuster that I've seen before include "Insurance assessor" , "One employed by an insurance company to assess claims" , "job in insurance" .)
