The risk of over-sharing - it's something creatives who share aspects of their personal lives with audiences really have to think about. Let Me Be Frank is the title of novellist and cartoonist Sarah Laing's latest book, a survey of her work from 2010 til now. She has mined her family life for her comics, which is what makes them so relatable to so many people. But it's also lost Sarah friends along the way because they didn't appreciate their stories being shared in her comics. Lynn Freeman asked Sarah Laing what made this the right time for a comics retrospective - a book that's also the portrait of a marriage coming undone.
