By the time [this book] came to be written, it was obvious that there would be great difficulty in getting it published; . . it was refused by four publishers. only one of these had any [moral] motive. two had been publishing anti-russian books for years, and the other had no noticeable political colour. one publisher actually started by accepting the book, but after making the preliminary arrangements, he decided to consult the ministry of information, who appeared to have warned him, or at any rate strongly advised him, against publishing it.
