In the shade is a dark place (5)
I believe the answer is:
hades
'place' is the definition.
(I have seen 'gloomy place' mean 'hades' so perhaps 'place' could also mean 'hades')
'in the shade is a dark' is the wordplay.
'shade' can be anagrammed to 'HADES'.
But, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for hades that I've seen before include "Greek god of the underworld" , "The underworld where the souls of the dead live" , "Mythological abode of the dead" , "Greek underworld with spirits of the dead" , "Infernal situation" .)
