Those who are familiar with the Angel Mountain Saga series will find some characters and settings that they know and love; but this story ranges far more widely, leaving West Wales behind and taking in episodes set in the industrial districts of Merthyr Tydfil, and in Paris. It is a strange story of an elderly lady who calls herself Susanna Ravenhill and who lives far more dangerously than is recommended for someone of her age. She has a dark secret to hide and she is pursued relentlessly by a group of armed men. One day they will catch up with her.
