'For some such reason as he had when he sent his men to hold the bridge at Carpignano while you were building bridges here. Bellarion's intentions are not clear to dull eyes like yours and mine, Carmagnola.'

Carmagnola considered him malevolently. 'You and I will discuss this matter further elsewhere,' he promised him. 'You have used expressions I am not the man to forget.'

'It may be good for you to remember them,' said the young captain, no whit intimidated. 'Meanwhile, madonna, I take my leave. I march my condotta out of this camp within an hour.'

'I am grieved, madonna. But my duty is to the Prince of Valsassina. I was seduced from it by too hasty judgment. I return to it at once.' He bowed low, gathered up his cloak, and went clanking out.

'Hold there!' Carmagnola thundered after him. 'Before you go I've an account to settle with you.'

Ugolino turned on the threshold, drawn up to his full height.

'I'll afford you the opportunity,' said he, 'but only after I have the answer to my question, whether you are a villain or a fool, and only if I find that you're a fool.'
