By one of those coincidences which are quite inadmissible in fiction, but of frequent occurrence in real life, an incident in the story of The Cat's Eye has found an almost exact duplicate in an actual case which has been reported in the Press.The real case was concerned with a most alarming misadventure which befell a distinguished police official of high rank. The fictitious incident occurs in Chapter Ten of this book; and the reading of that chapter will inevitably convey the impression that I have appropriated the real case and incorporated it in my story; a proceeding that the reader might properly consider to be in questionable taste.It seems, therefore, desirable to explain that Chapter Ten was written some months before the real tragedy occurred. Indeed, by that time, the book was so nearly completed that it was impracticable to eliminate the incident, which was an integral part of the plot.
