Death of a Showjumper details the shocking death of Katie Simpson, a promising young showjumper, which devastated the horse community in Northern Ireland, exposing hypocrisy, secrets and violence under the surface of a seemingly perfect and privileged world.

When Katie Simpson, died unexpectedly in 2020, the majority of the horse community accepted that she had taken her own life but a local journalist questioned the official conclusion. Katie's death triggered a memory of an old case she covered, a case with too many similarities to Katie's. At the centre of her suspicions was Katie's sister's partner, an influential champion showjumper, jockey and horse trainer, Jonathan Creswell.
