My early novels were very understated and English. Fourteen years ago, I met and married my American husband, and as I learned more about his background and culture, I became interested in using American voices.
Not so very long ago, certainly well into the Thirties, a lady companion was a normal feature of life for widows or lone spinsters.
My research process doesn't vary much. I do a little reading to establish a timeline and decide how I'm going to approach the story.
My husband is stricken with dementia, and it's a trick of his condition that events and people from his past are more real to him than what happened five minutes ago.
As one ages, eventually, no matter what regime you've followed, no matter how fiercely you've fought the fight, good health becomes harder to maintain. It may disappear overnight or simply dwindle, but with every year that passes, the odds shorten.
I was fascinated by the culture clash between England and America in the 1950s. My first memories are of being a girl in those post-war years when things were really pretty grim. It wasn't like that in America, which was real boom time.
