After the death of her sister is left unresolved, Esther is broken and alone. Searching for closure, she is increasingly drawn to the disturbing world of Keith. As their relationship progresses, the two spin webs of trickery and deceit - but who is the spider, and who is the fly? Can either of them escape their shared past? And will they emerge unscathed? John Webber's Spiderfly is a taut, thrilling debut play. It premiered at Theatre503, London, in November 2019.
