Hi all.
Re 20d - 'link' - 24ac - 'link' - 21d
The preamble states:
Their (ie the 6-letter solutions to go in the grid) clues refer partly to their own solution and partly to either neighbouring (concealed) link. Nb 'either' neighbouring link.
So I thought that the clues for 20d & 24ac both referred to the same 'link' - one 'forward'/ one 'backward' as it were.
'Give up work' & 'depart' can both define this 'link' word. This would mean the 'link' between 24ac & 21d is not referred to in a clue. Seems odd that this is the only one but I reckon the surface readings of:
'Give up work search' & 'Depart in peace' were too good to miss.
