Vitaly Stepanov worked for the Russian anti-doping squad, committed to his job; Yuliya Rusanova was one of the country's most promising 800m athletes. When they met, he fell in love with her; she revealed she was taking performance-enhancing drugs. It could have been the end of their relationship, but instead they decided they would reveal the scale and the scope of the corruption in Russian athletics - the bribes, the drugs, the abuse. 

In 1997, Jan Ullrich announced himself to the world by obliterating his rivals in the first mountain stage of the Tour de France. So awesome was his display that it sent shockwaves throughout the world of cycling and invited headlines such as L’Équipe’s ‘The New Giant’. He went on to become Germany’s first ever Tour winner, storming to victory in that edition by almost 10 minutes, a result that was greeted as an era-defining changing of the guard. Everyone agreed: Jan Ullrich was the future of cycling. 

They called him God. For his grace on a bicycle, for his divine talent, for his heavenly looks. Frank Vandenbroucke had it all, and in the late '90s, he raced with dazzling speed and lived even faster. The Belgian won several of cycling's most illustrious races, including Liège-Bastogne-Liège, Paris-Nice and Ghent-Wevelgem. He was a mix of poise and panache who enthralled a generation of cycling fans. Off the bike, he only had one enemy - himself. 

By his 18th birthday David Millar was living and racing in France, sleeping in rented rooms, tipped to be the next English-speaking Tour winner. A year later he'd realised the dream and signed a professional contract. He perhaps lived the high life a little too enthusiastically - he broke his heel in a fall from a roof after too much drink and before long the pressure to succeed had tipped over into doping.

German by birth, British by naturalization, Communist by conviction, Klaus Fuchs was a fearless Nazi resister, a brilliant scientist, and an infamous spy. He was convicted of espionage by Britain in 1950 for handing over the designs of the plutonium bomb to the Russians and has gone down in history as one of the most dangerous agents in American and British history. He put an end to America's nuclear hegemony and single-handedly heated up the Cold War. But, was Klaus Fuchs really evil?

When Browder’s young Russian lawyer, Sergei Magnitsky, was beaten to death in a Moscow jail in 2009, Browder cast aside his business career and made it his life’s mission to pursue justice for Sergei. One of the first steps of that mission was to uncover who had killed Sergei and profited from the $230 million corruption scheme that he had exposed. As Browder and his team tracked the money that flowed out of Russia—through the Baltics and Cyprus and on to Western Europe and the Americas—they discovered that Vladimir Putin himself was one of the beneficiaries of the crime. 

On a fateful night in 2009, Tyler Hamilton and Daniel Coyle met for dinner at a restaurant in Boulder, Colorado. The two had met five years before while Coyle was writing his best-selling book Lance Armstrong: Tour de Force. But this time, Tyler had something else on his mind. He finally wanted to come clean, about everything: the doping, the lying, his years as Lance Armstrong's teammate on U.S. Postal,, and his decade spent running from the truth. "I'm sorry," he told Coyle. "It just feels so good to be able to talk about this. I've been quiet for so many years."

On November 1, 2006, Alexander Litvinenko sipped tea in London's Millennium Hotel. Hours later, the Russian émigré and former intelligence officer, who was sharply critical of Russian president Vladimir Putin, fell ill and within days was rushed to the hospital. Fatally poisoned by a rare radioactive isotope slipped into his drink, Litvinenko issued a dramatic deathbed statement accusing Putin himself of engineering his murder.

Over the course of 15 years, John Delaney ran the Football Association of Ireland as his own personal fiefdom. He had his critics, but his power was never seriously challenged until last year, when Mark Tighe and Paul Rowan published a sequence of stories in the Sunday Times containing damaging revelations about his personal compensation and the parlous financial situation of the FAI. Delaney's reputation as a great financial manager was left in tatters. He resigned under pressure, and the FAI was left hoping for a massive bail-out from the Irish taxpayer. 

Simon Jordan made his fortune building a mobile phone company from scratch. When he sold it for £75 million, he bought Crystal Palace FC, the club he'd supported as a boy, and led them into the Premier League. Ten years later, Palace was in administration and Jordan had lost nigh on everything. Be Careful What You Wish For lifts the lid on being the owner of a football club and how the game really works. Hopes and dreams sit alongside greed, self-interest, dodgy transfers, boardroom fights and dressing room dressing downs. 

In his quest to define ‘sporting greatness’, double Olympic champion Alistair Brownlee has spent nearly four years interviewing and training with some of the greatest minds in sport to discover what it takes to become - and remain - a champion.

In Putin's People, former Moscow correspondent and investigative journalist Catherine Belton tells the untold story of the rise of Vladimir Putin and the small group of KGB men surrounding him. Delving deep into the workings of Putin's Kremlin, Belton accesses key inside players to reveal how Putin replaced the free-wheeling tycoons of the Yeltsin era with a new generation of loyal oligarchs who in turn subverted their country's economy and legal system and expanded its influence in the West.

Penguin presents the unabridged, downloadable audiobook edition of the revealing, inspirational memoir from the British winner of the Tour de France. The Climb tells the extraordinary story of Chris Froome's journey from a young boy in Kenya, riding through townships and past wild animals, and with few opportunities for an aspiring cyclist, to his unforgettable yellow jersey victory in the 2013 Tour de France.

In One-Way Ticket: Nine Lives and Two Wheels he describes a journey from driven teenage prodigy, travelling to races in the back of his dad's station wagon, to an obsessive determination to make it big in European racing - whatever the cost. He tells the story of his transformation from poacher to gamekeeper, detailing his painful decision to finally come clean about his own descent into doping - and to persuade others to do likewise - by providing more than enough shocking testimony to USADA (US Anti-Doping Agency) to explode the Armstrong myth.

We are in a new era: authoritarian leaders have become a central feature of global politics. Since 2000, self-styled strongmen have risen to power in capitals as diverse as Moscow, Beijing, Delhi, Brasilia, Budapest, Ankara, Riyadh and Washington. These leaders are nationalists and social conservatives, with little tolerance for minorities, dissent or the interests of foreigners. At home, they claim to be standing up for ordinary people against globalist elites; abroad, they posture as the embodiments of their nations.
