A Sunday Times bestseller and Twickenham mother-of-two is releasing her third book later this year.

Amanda Robson, 59, has a background in science. After graduating with a science degree, she worked in medical research at The London School of Hygiene and Tropical Medicine and at the Poisons Unit at Guy's Hospital.

She became a co-author of a book on cyanide poisoning. She stopped working after having her two sons to stay at home and bring up her family.

However, in 2011, when her children had grown up, she decided to follow her dream of becoming an author.

Amanda attended the Faber Academy Writing A Novel course and is now a full time novelist. She has lived in Twickenham since 1982 and lives with her lawyer husband, puppy, and kitten. Her two sons are also lawyers.

She has since released two novels, titled Obsession and Guilt, and is releasing Envy on April 4.

She said: "I always loved reading and dreamt of writing. I ended up doing a science degree, as at the time it got me a job. I am the least scientific scientist, writing and reading have always been a passion of mine.

"Science does come into my writing quite a lot, with themes of poisoning featuring in all the books so far. I am fascinated by the way society takes notice of good looking women and that is one of the themes in my books.

"Two of them, including Envy are based in Twickenham and the other is set in Bristol. There isn't really a specific theme in my books, the titles are actually written at the end.

"Science was never my passion and I am so glad I started writing. My next book is another psychological thriller, called Revenge. Envy is probably the most visual book and the one I would choose to be made into a TV show or film.

"The biggest challenge I have faced is the digital aspects of sharing news around but apart from that my age hasn't really hindered my progress."

Envy is a thriller about a woman named Erica who has always wanted to be exactly like her neighbour, Faye, who is "beautiful, thin, and a mother".

But Faye’s life isn’t as perfect as it seems – she has a terrible secret, and slowly but surely, it is threatening to destroy her and everything she holds dear.

When Faye’s daughter Tamsin goes missing after school, the police turn to Erica. But is Erica the only one who has been enviously watching Faye, or is there another threat hiding in the shadows?

The book will be available on paperback, audio and digital from April 4.
