Reminds me of Werner Herzog's autobiography. In the introduction, he muses on a life being cut short by a snipers bullet, and when he sees a bird flying past his window as he is writing his book makes him imagine it is a bullet and he thinks it would be a nice device to cut his final chapter short at that exact moment, so he is giving fair warning that the book will end abruptly.

And so it does, but in a totally Herzog moment he then almost immediately intones afterwards "and that is the end of the book as I indicated in the foreword".
