We're delving into the Outlook archive to bring you stories about parents who kept shocking secrets from their children.

In April 1997 a woman dressed as a nurse walked into a Cape Town hospital and left with a new born baby. The baby's name was Zephany Nurse - that child would not discover her true identity for another 17 years. This story was presented by Mpho Lakaje. Miche Zephany's book about her experience is called Zephany, Two Mothers One Daughter.

As a film-obsessed gay teenager, Wes Hurley was thrilled to move to the US from Russia. But his mother’s new husband was moody and homophobic. He told Outlook's Saskia Edwards how they ended up bonding, after a surprise revelation. Wes made a film about his life, co-directed by Nathan Miller, called Little Potato.

And if all this sharing of secrets has got you thinking about a story in your own life, we'd love to hear it. Write to us, or send a short voice memo to [email protected]. The secret could be about you or someone you know, or it could just be a fantastic tale you heard. If your story is about someone you know, just make sure they're ok with you telling us about it.
