S.J.I. Holliday is a pharmaceutical statistician by day and a crime and horror fan by night. Her short stories have been published in many places and she was shortlisted for the inaugural CWA Margery Allingham prize with her story 'Home from Home', which was published in Ellery Queen Mystery Magazine in 2017. She is the bestselling author of the creepy and claustrophobic Banktoun trilogy (Black Wood, Willow Walk and The Damselfly) featuring the much-loved Sergeant Davie Gray, and has dabbled in festive crime with the critically acclaimed The Deaths of December. Her latest psychological thriller is modern gothic with more than a hint of the supernatural, which she loved writing due to her fascination and fear of ghosts. She divides her time between Edinburgh and London.
