That Scoundrel Émile Dubois: Or The Light of Other Days

Dark humour and over-the-top Gothic adventure set during the time of the French Revolutionary Wars as two scoundrels are incongruously drawn into occult adventure. But the romantic Sophie and her maid Agnes are eager to come to the rescue.
Sophie de Courcy, bored companion to an elderly countess, dreams of adventure. When she meets her grand distant relative, the dashing Emile Dubois, she has more excitement than she ever dreamed of. Caught up in occult happenings with predatory half vampires and time warps, Sophie finds herself living in true Gothic style in an isolated mansion staffed by Emile's villainous accomplices.
With the help of her Tarot reading maid, Sophie must somehow help Emile to overcome the sinister changes that are happening to him and to defeat their evil, half-human neighbours who need his co-operation to further their occult schemes.
Set largely in isolated North Wales, this darkly humorous and sometimes sad story is both a spoof of Gothic and an occult adventure.
