“Night School” takes Jack Reacher back to his army days, but this time, he’s not in uniform. With trusted sergeant Frances Neagley at his side, he must carry the fate of the world on his shoulders, in a wired, fiendishly clever new adventure that will make the cold sweat trickle down your spine. This next instalment from one of the world’s leading thriller writers, Lee Child, takes Reacher “back to school”. But, it turns out that “school” means a vital and secret mission: a sleeper cell in Hamburg, Germany, has learned of an American traitor with something to sell to Islamic terrorists for $100 million. The U.S. president’s national security adviser tells Reacher and his fellow students, “we have enemies everywhere” and gives Reacher’s team its orders: “Your job is to find that American.” The premise of the pre-9/11 plot is both compelling and disconcerting and Child applies his trademark eye for detail to make the whole endeavour surprisingly and thrillingly credible.
