Impressive—how spies manage to remember maps and diagrams glimpsed for a moment, not miss details, and keep thousands of names, numbers, legends, rendezvous points, and passwords in their heads? You can learn this: in this book, the methods used in spy schools to develop memory are collected. In addition to theory and assignments for independent training, it covers communication techniques from the practice of the special services—how to quickly establish rapport, win over unfamiliar people, persuade your interlocutor, and verify the reliability of the information obtained. A separate section is devoted to self-organization: you’ll learn how to recover promptly and maintain high performance. The atmosphere of espionage is sustained by a running plot line—an investigation based on real events: the reader becomes a participant in the case while simultaneously improving attention, thinking, and memory. The book is for everyone who finds it difficult to remember things, wants to develop mental skills and become more effective in communication, work, and everyday tasks—making maximum use of the brain’s capabilities.
