After studying History at Oxford University, Tessa Harris began her journalistic career on a newspaper in her home town of Louth, in Lincolnshire. She progressed onto a London newspaper, where she became women’s editor. From there she moved to become a feature writer on Best magazine. After two years she was made editor of a regional arts and listings publication. This was followed by another two years as deputy editor on Heritage magazine. Motherhood meant a spell as a freelance, contributing to several national magazines, such as Country Homes & Interiors, Perfect Home and Woman’s Journal, as well as newspapers such as The Times, The Telegraph and The Guardian. During this time she also worked as a literary publicist and for a documentary-making company. In 2005 she was made editor of Berkshire Life magazine.
In 2000 she won a European-wide screenplay writing competition run by the London Screenwriters’ Workshop and the resulting screenplay was optioned by a film company. The script was set in 18th century London and her subsequent research led to the invention of Dr Thomas Silkstone, an American anatomist and the world’s first forensic scientist.
