The Warlow Experiment, Nathan Alix

Herbert Powyss lives in a large estate in the Welsh Marches, with enough time and income to pursue a gentlemans fashionable investigations and experiments in botany. But he longs to make his mark in the field of behavioral sciences--something consequential enough to present to the Royal Society in London. He hits on a radical experiment in isolation: For seven years a subject will inhabit three rooms in the basement of the manor house, fitted out with books, paintings, tapestries and even a chamber organ. Healthy meals will arrive thrice daily via a dumbwaiter. The solitude will be totally unrelieved by any social contact whatsoever; the subject will keep a diary of his daily thoughts and actions. The pay: fifty pounds per annum, for life.
Only one man is desperate to apply for the job: John Warlow, a semi-literate laborer with a wife and six children to provide for. The experiment, a classic Enlightenment exercise gone more than a little mad, will have unforeseen consequences for all included.
