Help needed with, er, closure:
12d) Shift for one cat in shirt needing work (10)
I have A?T?C?R?S?, and it looks like an anagram of cat in shirt = Antichrist,
but how is that “Shift for one”??
And while we’re at it:
12ac) A journey taken by river in ship (4)
I have AR?O, so it looks like Argo, although it might also be Arno.
