Jordan, thanks for the hint, but I am no further forward. Miranda means one of three things to me, namely a moon of Uranus, a character from The Tempest or the comedienne, Ms. Hart. Is one of these the Miranda you meant?
Incidentally, I may have unintentionally misled you in my original post: I only have 16 clashes and I suspect that the missing one is in 32 across, which I still cannot solve despite the hints earlier in this thread.
