Following a hit run at the Edinburgh Fringe Amy Powell Yeates' play Little Death arrives in London telling the story of a firm friends Debs (Rosa Robson) and Charlie (Olivia Forrest).

It's one of those friendships that starts at school, an intense friendship where they claim to know each other better than they know themselves - although there is just one intimate red line they can't cross. But can it survive life and adulthood?

We initially find Debs and Charlie in 1998, grieving and angry at hearing the news that Gerri has left the Spice Girls. The play then time-jumps at regular intervals, the date projected on the back wall, charting the journey of their friendship and connection as they grow up and their lives change.

The fun and fallouts of childhood become teen boy crushes, bras and periods. Plans for uni are formed but life happens around them influencing decisions and feelings in ways that perhaps weren't foreseen.

There is plenty of silliness and some bickering, but the solidity of their early friendship shows in the care they take over each other. They have each other's backs. To start with, at least.
