About the book: 1994 / In the previous issue of “Question Mark” we published a chapter from a book prepared by our publishing house, but never seen the light of day. Our readers really liked the chapter “The Vest Pocket of Death”, and therefore we decided to continue publishing materials from this book. In this issue you will read four chapters, united under the general title “Beyond the Threshold of the Possible?” We hope that reading will bring you pleasure.
