Wilkie Collins 
Hide and Seek 

Collins‘ third novel was his first "mystery" novel, but like his next, The Dead Secret, it’s not a conventional mystery as we know them today. Still, although there is no detective on the case, as Collins introduced in his most famous novel, The Moonstone, it’s still very much a novel about detection, in this case the quest to discover the origins of the beautiful Mary, or Madonna, left as a newborn in the care of strangers when her mother dies by the roadside, starving as a result of her leaving home from the "shame" of being pregnant and unwed.
