I started the clip at the beginning of the paragraph before the error, and continued into the abbreviated paragraph.
<br><b> &nbsp;&nbsp;&nbsp; Instead of following the drive down to the gate, M. Bex turned up a path that branched off at right angles. It led, up a slight incline, round to the right of the house, and was bordered on either side by a kind of shrubbery. Suddenly it emerged into a little clearing from which one obtained a view of the sea. A seat had been placed here, and not far from it was a rather ramshackle shed. A few steps farther on, a neat line of small bushes marked the boundary of the Villa grounds. M. Bex pushed his way through these, and we found ourselves on a wide stretch of open downs. I looked round, and saw something that filled me with astonishment.<br><b> &nbsp;&nbsp;&nbsp; 'Why, this is a Golf Course,' I cried.<br><b> &nbsp;&nbsp;&nbsp; Bex nodded.<br><b> &nbsp;&nbsp;&nbsp; 'The links are not completed yet,' he explained. 'It is hoped to be able to open them some time next month. It was some of the men working on them who discovered the body early this morning.'<br><b> &nbsp;&nbsp;&nbsp; I gave a gasp. A little to my left, where for the moment I had overlooked it, was a long narrow pit and by it, face downwards, was the body of a man! For a moment, my heart gave a terrible leap, and I had a wild fancy that the tragedy had been duplicated. But the commissary dispelled my illusion by moving forward with a sharp exclamation of annoyance: 'What have my police been about? They had strict orders to allow no one near the place without proper credentials!'

This is a clip of the shortened HTML file with error. It was in the debug input directory with the debug-raw.html file.
I see where the text stops being imported, but I can’t see why. (Ignore the apparent space between “with” and “astonishment”. It’s a line wrap artifact caused by the very large continuous ...</span></span>... code.)
The </span>’s continue to the end of the file.
