About the book: year / An interesting detective story from 1978 about the work of a computer security consultant. Interrupting with small orders, an excellent specialist finally reaches a high level, having achieved the signing of a complex and profitable contract. Of course, everything turns out to be far from so simple... The novel is dashingly twisted and written in vivid figurative language; In addition, it is full of interesting details of the daily life of computer scientists who worked with the famous IBM 370 at the very time when computers were big. And, of course, the reader will plunge headlong into the vibrant atmosphere of London in the 1970s. The translator’s foreword has been moved to the end of the work, as it contains spoilers and is also unpleasantly politicized.
