Cathryn is a Sunday Times bestselling ghostwriter, author and journalist, with a prolific career writing celebrity, inspirational, true crime and nostalgia titles. Her personal memoir Coming Clean won the Big Red Read Prize for Non Fiction, and she is a member of the Society of Authors.

A Poisoner's Tale is her first foray into historical fiction. When not writing, Cathryn can be found braving the waves off the south coast, or spending time with her young son and ginger cat in the glorious wreck of a house she is renovating in St Leonards-on-Sea, UK.
