Scratching my head about these two clues which intersect in the puzzle.:-
20D - Spiv accepting tips harbouring
admission of guilt. P-C-A-- (7)
28A - Groan perhaps about pub that's
buzzing. ---N-T-S (8)
Thanks again, Bullfrog! "Peccavi" was very cleverly hidden! If you did the whole xword, I thought the clue for 6 down "It prevents rocky ground etc." was brilliant.
Paul, do you know the story about Sir Charles Napier who was sent to India to put down a rebellion in the Sindh Province, but exceeded his orders and conquered the area. He sent a telegram back to London with the one word 'Peccavi', -- I have sinned.
