3 down: Keenly watching defended case about fine (5-4)
Having never heard of argus-eyed, the cryptic troupe vaingloriously inked in eagle-eyed as the answer while supposing the lack of an explanation had more than likely something to do with DA’s legendary legedermain. A quick squizz at Saturday’s Age after progress came to a stand still revealed our mistake.
Recourse to the iPhone revealed that argus-eyed does indeed mean keenly watching (it’s not the neatest grammatically — the clue should read keenly sighted defended case about fine in my book), and that Argus was a giant possessed of 100 eyes, all of which were engaged with the task of guarding the heifer Io, all of which were later transferred to the peacock’s tail after the giant they belonged to had passed away.
1 across: Offshore sea angers wild sea-duck (9)
Incorrect answers to cross clues prevented us from answering this one, but I thought I should note the special history of merganser here even though I already knew the meaning of the word. In a cryptic crossword from many moons ago, maybe even a DA, I stumbled across merganser as an answer and was duly informed of what it was. My advice: take care to remember merganser, for it will surely reappear in many a crossword to come; just like tango, eerie and rumba, there are too many handy letters for a crossword compiler to ignore this specimen of sea-duck.
