The hilarious and touching novel from Laurie Graham – the fictional diary of the Queen’s best friend in pre-war London. Laurie Graham's brilliant novel is the fictional diary of Maybell Brumby, a wealthy American widow who arrives in London in 1932 and discovers that an old school friend is in town: Bessie Wallis Warfield, now Mrs Ernest Simpson. Maybell and Wally are made for one another. One has money and a foothold in high society, courtesy of a sister who married well. The other has ruthless ambition and enough energy to power the National Grid. Before the year is out, Wally has begun her seduction of the Prince of Wales, and as she clambers towards the throne she makes sure Maybell and her cheque book are always close at hand. So Maybell becomes an eye-witness to the Abdication Crisis. From her perch in Carlton Gardens, home of her influential brother-in-law Lord Melhuish, she has the perfect vantage point for observing the anxious, changing allegiances for and against Queen Wally, and the political contours of pre-war London. When the crisis comes and Wally flees to the south of France, she insists on Maybell going with her. 'Are you sure that's advisable, darling?' asks the King. 'Of course it is,' snaps Wally. 'She's the Paymaster General.' Maybell's diary records the marriage, the Windsors' exile, and the changing complexion of the Greatest Love Story. It takes the sound of German jackboots at the gate and personal tragedy to make her close its pages for the last time.

Lydia Ackland was nearly blind when she fell downstairs and was killed. Her grandchildren have always accepted the official verdict – accident. Besides, they have their own problems: beautiful Kate is ending a love-affair; her brother Daniel is painfully crippled. But then that letter comes to light. Only days before her death, somebody wrote and warned their grandmother that she was ‘opening a disastrous Pandora’s Box’ and should ‘let sleeping, and perhaps dangerous, dogs lie’. The letter goads Kate and Daniel into asking lots of questions. First, who wrote it? And why does the answer, once discovered, point to their arrogant Uncle Mark, who, with his ambitious wife Helen, has inherited Longwater, the vast family estate, and the vast fortune that goes with it. Why were Mark and Helen banished from England in their youth and what are the secrets behind their long European exile? Kate follows their footsteps through Italy and Corsica, while Daniel continues to ask questions in England. Within days, both their lives have been threatened, confirming their suspicions that all is not a it seems – and perhaps never has been…

This is the true story of C.S. Lewis – one of the greatest writers of the 20th-century – whose books for children and adults have become much loved classics. Part of the story of C.S. Lewis has been made famous through the film ‘Shadowlands’. Here this fascinating man’s entire life story is told by those who knew him personally. C.S. Lewis was born in Belfast in 1898 and was sent to England for a public school education with his elder brother, Warren. Lewis exhibited a genius for imagination and perception from his earliest years. Brought up in a Christian household, Lewis lost his faith in his teenage years but was to regain it, with reluctance, as a fellow at Magdalen College, Oxford. His faith subsequently influenced his writings. He became a vigorous champion of the Christian faith through classics such as ‘Mere Christianity’ and through his BBC broadcasts. His ‘Chronicles of Narnia’ became children’s classics and he was deluged with correspondence from his young readers. In his latter years he unexpectedly fell deeply in love with a divorced American, Joy Greshem, and married her, only to suffer the devastation of her death a few years later. C.S. Lewis died in 1963 at his home in Oxford. During his lifetime C.S. Lewis suggested to his friend, Roger Lancelyn Green, who was a fellow English scholar, that he would undertake his biography one day. After Lewis’s death in 1963 Lancelyn Green and Walter Hooper were approached by several of Lewis’s friends to write the biography. Warren Lewis, brother to Jack, contributed a great deal to the writing. The authors had at their disposal a vast collection of letters and diaries, as well as the recollections of many surviving family members and friends. Walter Hooper has enhanced the original text with additional material to provide a new, expanded edition which all C.S. Lewis fans will be keen to own.

At the age of only 36, Sir Mark Sykes was signatory to the Sykes-Picot agreement, one of the most reviled treaties of modern times. A century later, Christopher Sykes’ lively biography of his grandfather reassesses his life and work, and the political instability and violence in the Middle East attributed to it. The Sykes–Picot agreement was drawn by the eponymous British and French diplomats in 1916 to determine the divide of the collapsing empire in the event of an allied victory in World War I. Excluding Arab involvement, it negated their earlier guarantee of independence made by the British – and controversy has raged around it ever since. But who was Mark Sykes? A century on, Christopher Simon Sykes reveals new facets of a misremembered diplomatic giant. Using previously undisclosed family letters and cartoons by his grandfather, he delivers a comprehensive and humbling account of the man behind one of the most impactful policies in the Middle East.

Cats are now the most popular pets, and it is not surprising that they have overtaken dogs in the popularity stakes. They are small, relatively silent, economical to keep, exercise themselves, easy to feed, and are ideal companions for a wide range of people, from the elderly to those who are out at work all day.Whether you want an ordinary moggie or an expensive pedigree cat, the principles of ownership and looking after them are the same. As an increasing number of owners live in big cities and small, high-rise apartment blocks, house cats are becoming more widespread. Although they may not be allowed outside like their free-roaming, predatory cousins, they share a common ancestry and owning a cat of any description is like having a relatively wild creature living with you in your home. Domestication is anathema to many cats who prefer to think that they are independent animals, under the control of nobody but themselves.
