Optical illusions are the stuff of magic - harmless entertainment conjured up to both enthral and amaze, aren't they? Well, maybe not, as it's not quite so amusing if the 'stunt' takes the form of an episode of the BBC's 'groundbreaking' documentary series MacIntyre Undercover on organised football hooliganism, the wizardry is conducted by unscrupulous investigative journalists posing as big-time drug dealers, and as a result the unwitting participant in the trick, avid Chelsea supporter Jason Marriner, is charged with conspiracy to commit violent disorder and affray, together with his friend Andy Frain, and Jason ends up with a six-year jail sentence for a crime he didn't commit. This is Jason's chance to put the record straight, present the facts from his own perspective and challenge the reader, who may well have been one of the 7.4 million documentary viewers, to decide whether the programme actually revealed the 'ugly face of football violence', or indeed showed him plotting or committing any violence whatsoever, or whether the original 344 hours' worth of footage, secretly filmed over a period of 18 months, were distorted beyond recognition by cutting, editing and stitching together clips from the original sequences to achieve the programme's aim at any cost. Jason would be the first to admit that in the past he had been a 'nuisance' on the terraces, but this was the late 1990s and, with a wife, children and his own business, he had done a lot of growing up and moving on. Fortunately, he had also developed the strength of character needed to survive in prison with humour, dignity and determination, and he shares his insights of life behind bars as he tried to work with the system, despite the knock-backs, in order to make it work for him in return. 'Good will always follow bad' is Jason's admirable philosophy about his experiences, but this shocking real-life story serves as a warning to all: this could so easily happen to you.

When Jarra Brown hears church bells he cannot fail to be reminded of the hundreds - 345 to be precise - of service personnel who passed through the beautiful rural Wiltshire countryside into Oxfordshire. These men and women were not hiking across its green pastures or sitting on top of the number 55 bus, instead they were lifeless, resting inside a coffin draped with the Union flag. By the end of August 2011 the bells of St Bartholomew's Church in Wootton Bassett had tolled more times than the residents of this once peaceful town cared to think about, for each chime represented the moment the police convoy accompanying the hearse from RAF Lyneham entered the High Street. A moment frozen in time, a moment when the residents of this town came to show their respects, a moment that couldn't have been more fitting even if it had been choreographed. There was no call to arms by the Town Crier, just a spontaneous, modest and unprompted response to those who had paid the ultimate price in the name of duty. 46 Miles is not a book about the politics of war, the whys and wherefores of the Iraq and Afghanistan conflicts, or indeed the hidden agendas and government strategies. It is about a town which captured the hearts of our nation and whose emotions rippled the entire 46 mile journey of honour, dignity and respect into Oxford. It is dedicated to those 345 people who, having signed up to serve their Queen and country, paid with their lives. Wootton Bassett, who nurtured the grieving on every occasion, wanted to let the nation know that these heroes will never be forgotten.

Squeezed between more powerful France and Spain, Catalonia has endured a violent history. Its medieval empire that conquered Naples, Sicily and Athens was crushed by Spain. Its geography, with the Pyrenees falling sharply to the rugged Costa Brava, is tormented, too.Michael Eaude traces this history and its monuments: Roman Tarragona, celebrated by the poet Martial; Greek Empuries, lost for centuries beneath the sands; medieval Romanesque architecture in the Vall de Boi churches (a World Heritage Site) and Poblet and Santes Creus monasteries. He tells the stories of several of Catalonia's great figures: Abbot Oliva, who brought Moorish learning to Europe, the ruthless mercenary, Roger de Flor, and Verdaguer, handsome poet-priest.Catalonia is famous today for its twentieth-century art. This book focuses on the revolutionary Art Nouveau buildings (including the Sagrada Familia) of Antoni Gaudi. It also explores the region's artistic legacy: the young Picasso painting Barcelona's vibrant slums; Salvador Dali, inspired by the twisted rocks of Cap de Creus to paint his landscapes of the human mind; and Joan Miro, discovering the colours of the red earth at Montroig.

Everyone on deck! All hands on deck! Fire! Fire! Bring the hose quick! As the steamship lurched in the heavy seas, Harry Braham grabbed what clothes he could and struggled with the other terrified passengers to climb the ladders. On deck, with the rain lashing down and the wind howling, he gripped the rails of the ship tightly, trying to stay upright. With horror he saw the flames leaping high in the hold and he thought his time had come.It was June 1891. A music-hall star famous for his comic songs and his ability to 'pull mugs', Harry - a seasoned traveler - was on his way from New York to his home in London, after a busy season appearing in a play by W H Crane. As the crew prepared the lifeboats, Harry looked back at his life - his apprenticeship with the Royal Christy Minstrels, his acclaimed tours of Australia and the USA, and his marriage to the vivacious but temperamental singer Lizzie Watson. Was this to be the end? In this well-researched and lively biography, full of fascinating social background, Janet Muir (Harry Braham's great-great-niece) brings to life the world of the Victorian music-hall and traces Harry's career from minstrelsy through to 'legitimate' theatre and finally to moving pictures, where he landed a part in D W Griffith's Birth of a Nation.
