Welcome to world of Horatio Lyle: Victorian London at the height of the industrial revolution. Horatio is a former Special Constable with a passion for science and inventions. He's also an occasional sleuth to the stars of the day (including Queen Vic), albeit a reluctant one. Truth be told, he'd rather stay up in his lab tinkering with his equipment but whenever a case is referred to the Lyle household he invariably gets badgered into taking it on by his daughter Tess. She's the one with the lust for adventure, and - much to Horatio's chagrin - a rather too business-end interest in the arts of crime. Together they make a formidable team - and they need to be. Because as well as the usual cut-throats, pickpockets and rapscallions of the urban underworld, Lyle, Tess and their faithful bloodhound Tate, are soon crossing swords with some selected nasties from another dimension - such as devilishly cunning band of High Faeries who want London and its associated technological terrors levelled to make more space for the Great Hunt. The plot will be packed with sleuthing and mystery - with added supernatural sparkle.
