I am finding this tough.
Preamble is long. But here it goes:
The grid should be considered to consist of three zones, each containing the same number of cells but with shapes and locations to be deduced. Thirteen answers are too long for the space available so some letters (dependant on the zone in which
they would have been located had there been sufficient space for the entry) must be removed to make them fit. A single letter must be removed from eighteen other
clues before solving. In clue order,these letters give an instruction which solvers must follow in the context of the deleted letters.
Help with:
24 Giving power to revenue ultimately can counter conspicuous wealth (8)
34 Lacking grace, inane gent beginning to look stupid (9)
4 Olid hospital pet still mostly lousy (7)
23 Freshly put down lawn died abruptly. Ridiculous! (6)
