The idea for my novel Don’t Ask was inspired by my partner’s mother. Lesley took a DNA genealogy test out of idle curiosity only to discover the identity of her biological father – a family secret for years. Her shock and surprise was equalled only by the other family involved who quickly shut down any further contact. Is it better to know, or not know? I talk about this, and much more, in this interview with Matador Books. Duration: under 5 minutes.
