In the tradition of ‘Agent Zigzag’ comes a breathtaking biography of WWII’s ‘Scarlet Pimpernel’ as fast-paced and emotionally intuitive as the best spy thrillers. This celebrates unsung hero Robert de La Rochefoucauld, an aristocrat turned anti-Nazi saboteur, and his exploits as a British Special Operations Executive-trained resistant A scion of one of the oldest families in France, Robert de La Rochefoucauld was raised in a magnificent chateau and educated in Europe’s finest schools. When the Nazis invaded and imprisoned his father, La Rochefoucauld escaped to England and was trained in the dark arts of anarchy and combat – cracking safes, planting bombs and killing with his bare hands – by a collection of SOE spies. With his newfound skills, La Rochefoucauld returned to France and organized Resistance cells, blew up fortified compounds and munitions factories, interfered with Germany’s wartime missions and executed Nazi officers. Caught by the Germans, La Rochefoucauld withstood months of torture and escaped his own death sentence, not once but twice. More than just a fast-paced, real-life thriller, The Saboteur is also a deep dive into an endlessly fascinating historical moment, revealing the previously untold story of a network of commandos, motivated by a shared hatred of the Nazis, who battled evil and bravely worked to change the course of history.

It was always tense in The Rooms when they were proposing to elect a statesman to membership. Actually, it was always tense in The Rooms whomever they were proposing to elect to membership. But a statesman created a special feeling of apprehension. Such an event happened only every fifty years or so, because, by and large, the Jockey Club did not see statesmen as the right calibre of chap. Most of them had depressingly brilliant intellects coupled with dazzling charm and tact. Or, put in the more ducal vernacular of the Club, they were too clever by half, ‘too smarmy’.The Earl of Rosebery, during his Lordship’s tenure as Prime Minister of England, had of course been a member of the Club back in 1894 when his colt Ladas had won the Derby at Epsom. However, having been a member since the age of twenty-two, the touchy business of electing a statesman had never really applied.The Jockey Club had admitted an Under-Secretary of State for War, Earl Cadogan, in the middle of the nineteenth century, in the knowledge that he was much preoccupied with the unrest along India’s north-west frontier. The same applied, in smaller measure, to the Marquis of Londonderry and the Earl of Zetland in the 1880s when they were appointed as successive Lords-Lieutenants of Ireland. Different frontier, similar unrest among the natives and one or two furrowed brows in the Club. Lord Randolph Churchill, Chancellor of the Exchequer and owner of an Oaks winner in 1889, had had to be elected. And they could not quite avoid accepting his often fractious son Sir Winston, who won the Jockey Club Cup in 1950 with his stout-hearted grey Colonist II shortly before becoming Prime Minister for the second time.

The Times has the most famous letters page of any newspaper. This delightful selection of over 300 items of correspondence over the last century shows precisely why. As a forum for debate, playground for opinion-formers, advertising space for decision-makers and noticeboard for eccentrics, nothing rivals it for entertainment value. By turns well-informed, well-intentioned, curious, quirky and bizarre, since 1914 it has taken the temperature of the British way of life and provided a window on the national character. Among those who have written to The Times to have their say are some of the major political and literary figures of the modern era, including Margaret Thatcher, Benito Mussolini, Graham Greene and John Le Carré. There are contributions, too, from Agatha Christie, Alastair Campbell, AA Milne, Yehudi Menuhin, Theresa May and Morrissey. If you want to know why kippers are dyed, who first turned up their trousers, how to make perfect porridge or just how to have a letter printed in The Times, this infinitely witty, diverting and memorable anthology should be, sincerely, yours.

Adapt the basic script components of Academy, Agent, and Brain to be used with Q Learning. ? Enhance the Q Learning model with improved training strategies such as Greedy-Epsilon exploration ? Implement a simple NN with Keras and use it as an external brain in Unity ? Understand how to add LTSM blocks to an existing DQN ? Build multiple asynchronous agents and run them in a training scenario In Detail Unity Machine Learning agents allow researchers and developers to create games and simulations using the Unity Editor, which serves as an environment where intelligent agents can be trained with machine learning methods through a simple-to-use Python API. This book takes you from the basics of Reinforcement and Q Learning to building Deep Recurrent Q-Network agents that cooperate or compete in a multi-agent ecosystem. You will start with the basics of Reinforcement Learning and how to apply it to problems. Then you will learn how to build self-learning advanced neural networks with Python and Keras/TensorFlow. From there you move o n to more advanced training scenarios where you will learn further innovative ways to train your network with A3C, imitation, and curriculum learning models. By the end of the book, you will have learned how to build more complex environments by building a cooperative and competitive multi-agent ecosystem. Style and approach This book focuses on the foundations of ML, RL and DL for building agents in a game or simulation

No. Not possible. It can't be him… Jordynn Flannigan was sure her fiancé was dead—along with all their dreams for a future together. But the stranger who just saved her from a kidnapper is none other than Donovan Grady, who supposedly died ten years ago. Now his enemies have found Jordynn, and he's not going anywhere without her by his side—and under his dangerously close protection… Donovan had to disappear to save those he loved. He can't ask for Jordynn's forgiveness, but he can keep her safe while they unravel an insidious conspiracy. As their reignited passion proves too hot to resist, the truth strikes devastatingly close to home. And their second chance might prove the most deadly trap of all.
