afternoon all. Think I may have made a mistake with 13D Clue Property owner disguised here in file - I did have Proprietor (10)- but it does not fit when I have done the other across clues.
I have "bisected "for 21A - clue: International cult engaged in plot split in half.
What is 25A Study of figures in morgue only after treatment (10)
11A Rebellion in Sweden given priority (10) I???R?E?C?
28A Former president is crazy about housing (7) M???S?N
thanks
