When it comes to crime fiction, mothers are too often cast as one-dimensional, tragic or hysterical minor players. Shaking up the tired tropes, gripping new novels by Jane Caro (The Mother), Dinuka McKenzie (The Torrent) and Laura Elizabeth Woollett (The Newcomer) unfold through the eyes of complex, deftly drawn mothers pushed to their limits absolving, avenging and protecting their families. The authors sit down with Suzanne Leal to discuss why mothers provide such engaging and humanising perspectives in crime writing.
