4 across. Rossetti's little flame (9) 10 across. Church vision (5) 12 across. Pile made from ghostwritten ghost story by H.P. Lovecraft. (3,5) 7 down. They had an invitation to the ballet. (3,6) 8 down. Version of 10 prepared to defend itself. (5) I found this puzzle a real stinker! Any help gratefully received. Thanks.

Thanks too, Get Over It. You confirm my thoughts of guests for 7 down.
