A disastrously ill-judged crush on the gentleman next door, an inheritance letter mistakenly sent to the wrong beneficiary; these are the ingenious premises of Lisa Jewell’s and Ruth Ware’s latest novels. How does a thriller writer know when the right premise demands to be developed into a novel? Two highly inventive authors discuss the well-springs of inspiration.

Since her first book, Ralph’s Party (1998) Lisa Jewell has published another fourteen books which have demonstrated a remarkable versatility and development in subject and style.  Recently, she has made the transition into the realm of domestic thrillers with consummate mastery and brilliance.

A former bookseller, TEFL teacher and press officer, Ruth Ware is the author of four splendid psychological thrillers which have appeared on bestseller lists around the world. The Woman in Cabin 10 was a number one New York Times bestseller.  Her latest novel is the Death of Mrs Westaway.
