Top half of grid represents the Third Circle of Hell:
across clues to five of the six rows are double,
with one answer normal and the other a glutton,
which must lose a letter (spelling a jumble of DANTE)
to form another word and be surrounded by
RAIN, HAIL, MUD, MIRE or SNOW on entry.
Each of three down clues is a triple definition
to three words differing in their initial (unchecked) letters,
which lie in the remaining row;
the correct choice produces CERBERUS (to be highlighted)
in the centre of the row.
Bottom half of grid represents the Fourth Circle of Hell:
answers to across clues are entered with weights reversed
(eg, ANNOUNCE becomes ANNECNUO).
Subsidiary indications in remaining down clues involve extra letters,
spelling PLUTUS: “PAPÈ, SATAN, ALEPPE”;
the spoken words also appear as unclued lights,
with the second extended to SATANIST.
