Here’s where you ask your questions and work out what DA is up to.
Update: I’ve got quite a few questions:
17, 15 across: The absolved gain this spare band in church (5, 5)
Something about an altar?
18, 24 down: Travel agent in decline, suggesting Italian tourist attraction (7, 5)
Guessed the attraction, not the wordplay.
3 down: Rivkin and coterie causing mortification? (8)
Should this clue have been Coterie and Rivkin causing mortification?
13 across: Flower cut back by lair by some 5 metres (9)
7 down: Eradicate qualm, say? (4, 3)
Wipe out sent me far down the wrong track.
