This week's Booksletter takes readers on a varied journey, moving from the music of Nino Rota to the secrets hidden in KGB archives, from the melancholic imagination of a fictional killer to the struggles of patients recovering from brain injuries. The selection of five books offers different lenses through which to examine the intersections of art, history, medicine, and science. Each book explores how these fields reshape our understanding of the world. Nino Rota's music is often closely tied to the films of Federico Fellini, with whom he collaborated on 17 projects. It is hard to imagine classics like La Strada or La Dolce Vita without Rota's scores. Beyond cinema, Rota's work includes theater, television, and concert music, such as symphonies and operas. He composed for over 170 films, including Le Guépard and The Godfather, leaving a lasting impact on both film and classical music. Gordon Corera revisits the story of Vassili Mitrokhine, a former KGB employee who spent years copying and removing classified documents. These documents were not only embarrassing to Soviet intelligence but also to some of their Western counterparts. The leak of these files had significant consequences, revealing secrets that reshaped perceptions of Cold War espionage and intelligence operations. Edgardo Scott's novel Yo soy como el rey de un país lluvioso (I am like the king of a rainy country) is inspired by the works of Charles Baudelaire and is steeped in a sense of melancholy. The book blends narrative, diary entries, medical details, and criminological themes, following a man who explores and documents his own desires until they become an unsettling obsession. Orlando Swayne's How to Use a Fork: Stories of Mending the Broken Brain examines the challenges faced by patients recovering from brain injuries. The book traces the evolution of neurological rehabilitation, from early 20th-century methods that often left patients isolated to modern techniques that offer greater hope for recovery. It highlights the resilience of the human brain and the progress made in medical science. Alexander Krauss's The Engine of Scientific Discovery: How New Methods and Tools Spark Major Breakthroughs challenges the idea that scientific progress is solely the result of individual genius. Instead, Krauss emphasizes how new tools and methods, such as microscopes and DNA analysis, have been crucial in driving major scientific advances. His book offers a fresh perspective on the collaborative and technological nature of discovery. In a related development, the Russian State Library has reportedly collected about 18,000 Ukrainian books in Moscow. The library describes these books as "nationalist" or "Russophobic" and has placed them in a special deposit for researchers. The books are said to have come from Ukrainian territories currently under Russian control. The library's director, Vadim Duda, frames the move as a conservation effort, but Ukrainian authorities view it as part of a broader strategy to erase Ukrainian cultural identity.
