Imagine a tiny village in Cambridgeshire, England…

It boasts one pub, one shop, one café and a garage. Just outside the boundaries stand a performing arts college and a posh hotel, and the Carlysle Estate and home farm snuggle around the village like arms.

I say ‘imagine’ because that’s what I did.

It began on a family car journey when I had a road atlas open on my lap. I loved the place names I was reading…Crowland…Eye…Whaplode Drove. For fun, I filled the gap between them by creating Middledip village and the nearby town of Bettsbrough. As we passed through the real-life village of Eye, I spotted a garage forecourt full of classic cars and mentally transferred it to Middledip village as MAR Motors, Ratty’s garage. A short, black, peacefully grazing pony in a roadside field became Snobby, Gabe’s cantankerous equine buddy. A few miles on, a stone pub looked just right to be The Three Fishes. A shop with one of everything in its window was perfect for Middledip, too, as was the village hall and playing field I borrowed. So Middledip took shape.

As we waited at traffic lights, I watched two women chatting. One, with long, strawberry blonde hair, looked awkward until children joined the conversation, and then suddenly she relaxed, smiling and laughing. That was when Tess Riddell was born – the first character to arrive in Middledip feeling lost and looking for a new beginning. (See Starting Over.)

Ten books on, I have a spreadsheet of characters that my brother maintains for me, because, although every visit to Middledip is a standalone story, I let earlier characters pop up so readers can see how they’re doing. There’s a spreadsheet for places, too, but I rarely need to refer to it because I just know that the cottages are stone, and there are also red-brick Victorian houses, like the neglected property that became The Angel Community Café. My hand-drawn map of Middledip (pictured) is probably the one item I’d try to save if my house burned down! A version can be found on my website here and you can click on the markers to discover where characters from various books live.

This year’s winter story is A White Christmas on Winter Street. As there was a foster carer in the village, Nan Heather, I wanted to bring back one of the children she had fostered – Sky Terran. I give Sky an overwhelming wish not just to visit the village but to truly be part of it, so let her buy a house on the corner of Winter Street. The Corner House has been neglected for so long that it can scarcely be seen behind an explosion of conifers and shrubs. Sky has the task of restoring it to order as part of the process of sorting out her life.

As ‘make friends’ is written at the top of her wish list, I provide her with every opportunity to find them, not just in Winter Street but via the pub quiz or grabbing a coffee at the community café where Christmas shortbread is in the shape of angels. I’ve been told by readers that reading a Middledip novel is like being in a Christmas movie – but I think it must be more like living in a snow globe because the village certainly sees an inordinate amount of snow and frosty wintry weather!
