In The Night Watch, due soon though still unscheduled, she plays Kay, a lesbian ambulance worker who sifts through bombed houses for bodies. “After the war, she’s utterly broken – and not just by heartbreak, but also by the fact that she believes the war is going to be a pivotal moment for the lesbian movement, that things will change and gay women will be out and proud like her. But that isn’t the case.”
It’s a racy book. “Oh my goodness! I have all my saucy scenes with Claire Foy – it’s like Little Dorrit and Esther Summerson getting off with each other!” (Foy played the lead in the BBC’s 2008 Little Dorrit.) Doing sex scenes with a woman, says Maxwell Martin, is much better than with a man. “In Claire and my case, we’re heterosexual, so it’s purely acting. But with a man, you’re like, ‘Oh God, does he think I fancy him, does he think I’m minging, is he going to get an erection?’ It’s awful.” She whoops with laughter.
