Anger swiftly chasing his sadness, he decides to visit a cheap quayside inn to escape the loneliness he feels and drown his sorrows. Sitting alone, his mind firmly fixed on how the woman he loved has betrayed him, he vows never to love or trust again. But Fate seems determined to challenge him as almost immediately he is forced to act as a ‘Good Samaritan’ to protect a young lady, Ola, intent on escaping the clutches of her hateful stepmother and dishonourable cousin. Blaming his act of charity on the vast quantities of brandy he consumed and against his better judgement, he offers to sail her in his yacht, The Sea Wolf, to Calais.

But Fate has not finished meddling yet and they are soon embroiled in incredible adventures, too fantastic for either of them ever to have imagined, that push their friendship to its very limits.

The handsome and aristocratic, thirty-five year old diplomat Lord Athelstan knows that he is heading for trouble on his mission to the Caucasus to investigate how long the legendary Shamyl, the Imam of Daghestan, can hold out against the invading Russians. But little does he expect to be faced with another kind of conflict – with a beautiful young hostage imprisoned in the Imam’s stronghold. The lovely Natasha is only nineteen and she was seized along with a Royal party by the Imam’s followers and held to ransom against the release of the Imam’s only son by the Russians. Orphaned, she has no hope of raising a ransom and instead has reluctantly agreed to be given to the Sultan of Turkey as a ‘wife’ for his vast harem in return for the release of her nine-year-old brother. The Imam implores Lord Athelstan to escort Natasha safely to Constantinople – a favour he cannot grant lest it anger the Russians and compromise Great Britain. But then he meets her – undoubtedly the most glorious woman he has ever seen, with fire in her eyes, when he informs her that he cannot agree to Shamyl’s request. Ultimately Natasha gives him no choice and, when she appears among his party in disguise, Lord Athelstan is furious. Soon their mutual hatred turns to all-consuming love – a love surely doomed by Natasha’s pledge to sacrifice herself to the Sultan’s harem for the sake of her brother –

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.

Among the highlights are the house in Cheltenham where he was born (now the Holst Birthplace Museum) and several venues in the Cotswolds where he played, conducted and taught music.

The house has been carefully restored and converted into a ‘living museum’ that captures the atmosphere of the era, both above and below stairs. The most eye-catching of the museum’s collection of 3,000 items is the piano on which Holst composed The Planets, as popular as ever nearly 100 years after it was published. Step inside the Museum and see the piano Holst used to compose The Planets. Find out how he developed into a world-class composer by examining and listening to original manu*s written when he was a schoolboy in Cheltenham. "
