Was furious about hospital that glistened (9)
I believe the answer is:
shimmered
'glistened' is the definition.
(shimmering is a kind of glistening)
'was furious about hospital' is the wordplay.
I cannot quite understand how this works, but
'about' could be 're' ('re' means regarding or about) and 're' is located in the answer.
'hospital' could be 'h' (abbreviation for hospital on maps) and 'h' is located in the answer.
This explanation may well be incorrect...
'that' acts as a link.
Can you help me to learn more?
(Another definition for shimmered that I've seen is " shone".)
