Sadly I haven't got the crossers, yet, only ?C????. Does 16 across refer to piano pieces by Satie? It fits the letters I have and has the 3 letters but I am at a loss to parse it.
Yes 16a refers to Satie. Without giving too much away first two letters is one short of pain, 4 letter series of the special instructions then an old pet name for a girl(s).
Yes a tough one which took longer than it should until I reread the instructions. I missed the bit where it said both solutions could have a series of letters which left me scratching my head quite a bit.
