John Clare (1793-1864) was born at a time of great social upheaval, just months after the beheading of Louis XVI and the outbreak of war with France which was to last till the defeat of Napoleon at Waterloo in 1815. He also lived through the upheavals of the land enclosure movement and agricultural revolution which changed the face of the countryside and the way of life in rural England. His father was a farm worker who managed to pay for his son’s schooling, though this was cut short as conditions worsened, but at least Clare had by then learnt to read and write so he could continue his own education, reading whatever books he could lay his hands on. At the age of sixteen he witnessed the social dislocation caused by the local enclosure Act and observed how the landscape was gradually transformed. Drawing on Clare’s writing, this extensively researched study gives the modern reader an appreciation of the divisive effects of these policies. Structured chronologically, this exploration of John Clare’s life highlights the socio-economic and environmental aspects of his observations and includes his reports on an insidious revolution taking place in the English countryside. Parliament, dominated by landowners, authorised the enclosure of large tracts of common land by private acts without considering the effect on those who had enjoyed rights of use and pasturage for centuries. Land enclosures, and the improved agricultural techniques which this permitted, was important in increasing food production at a time when the population of England was growing rapidly. While additional work was initially provided for agricultural labourers in the fencing and walling needed, this was temporary. The introduction of new, labour-saving machinery further reduced the opportunities for work. Insufficient attention, the author argues, has been given to the consequences. Those driven out of their homes in the country were left with no option but to migrate to the towns and sell their labour to whoever would pay for it. In effect, land enclosure created a market in land; landlessness created a market in labour. These are the foundations of our modern market economy. The author asserts that the harshness of the early years of the industrial revolution were the product of land enclosure which the welfare state has to some extent mitigated, although at the cost of creating a dependency culture in contrast to the sturdy independence of Clare’s parents’ generation of farm workers.

Soon Zaria finds herself secretly taking the place of the young lady employed for the job and, after meeting in strange circumstances the handsome Chuck Tanner, who is in desperate need of her assistance and she then becomes embroiled in a maze of subterfuge and deceit.
