Second paragraph of Chapter 3:

‘Tertius!’ She had intended a whisper but it came out as a hiss.

Second paragraph of the notes to Chapter 3:

A ROMAN ATRIUM
During the Roman Empire, and in the houses of the wealthy, the atrium was the reception room of the house. They were light, airy spaces, lit by the compluvium: a hole in the roof that was designed to let rainwater into the impluvium, a marble lined pool below. The householder would often sit on the opposite side of the impluvium, facing the vestibule or hallway, and hence the guests who entered the house. Although in the period of the Roman republic the atrium was often a family room, by the time of the empire it was a much more formal reception area, with family rooms located towards the back of the house. Even non-citizens like Lydia would have been accustomed to treating the space in this way.

This is basically New Testament fan-fiction, linking a woman mentioned in Acts with a passage from Philippians and telling a story about St Paul. There are 212 pages of plot and 106 pages of notes, which gives you an idea of the writer’s priorities and how seriously she has taken it. I lasted until the first miracle and then couldn’t manage any more. You can get it here.
