Fancy writing a time-slip mystery romance novel? How hard can it be? All you have to do is tell the story of someone from the present day finding herself in a different time – easy, right? Wrong! In fact it’s pretty difficult. There are all sorts of issues you have to work out. Why would this person suddenly fall into another time period? How would she do it? What would be the trigger? If she could do it, why couldn’t everyone else? What makes her have this unique ability?

I love reading time-slip; I’m especially keen on Pamela Hartshorne’s novels of time-slip into the Tudor age in York (Time’s Echo, House of Shadows). They’re intriguing and exciting. I’m fascinated by theories of time and the whole concept of what time actually means? All these weird and wonderful theories: quantum mechanics, the Einstein-Bridge theory of portals and worm-holes … Is it all weird – or does it make sense?

When I wrote A Shape on the Air, I’d wanted to write a time-slip story of my own for a long time, but in my case one set in the early medieval times because that’s the period I know best and am most interested in. And I wanted an intriguing mystery involved in the dual time periods. But working it all out resulted in many a restless night, loss of hair and bitten fingernails! I wanted the tone and atmosphere to be a little spooky but still feel realistic and convincing (which isn’t easy if you’re writing about what we normally think of as ghosts). In the end I found writing the ghostly parts the easiest and the mechanics of the time-slip the most difficult.

It seemed to me that my main character, Viv, needed to be someone that anybody could identify with, someone pretty ‘normal’, but make her have a traumatic event in her life which might make her vulnerable and more susceptible to the paranormal. I made her an academic who deals with facts not fantasies, and gave her an awful partner in Pete who announces that he’s leaving her for her best friend – goodness, that would send anyone off balance! – and made her lovely home and the life she knew be at risk. I also made her drink rather a lot of red wine (understandable in the circumstances!) then go for a walk beside a lake!

I then had to make someone in a responsible job commanding authority and respect, empathise and become involved with her strange experience. Who might believe her? Someone whose job is connected with other-worldly things but could be a ‘pillar of society’? It had to be a vicar. So Rev Rory was born. And so was the love interest.

Although it would have been easier for the time-slip trigger to be the lake that started it all off, I didn’t want it to be that obvious, so I had to create a whole back-history for Viv, involving her parents, especially her mother, and their untimely death. Gradually it was coming together like a jigsaw. I can’t explain any more because it would give away the secrets of the book. You’ll just have to read it and find out! I hope you feel intrigued enough to do that, and I hope you enjoy the story. I certainly enjoyed writing it – and guess what? There are two sequels already in the pipe-line, so I’ve had to work it all out again with completely different plots!

And many thanks to the reviewer who said: “she makes the fantastical believable.”
