'You take too much for granted. The letter suffices fully. You forget that it is not all the evidence against you.'

'What? Is there more?'

'There is your failure last night to make the false attack you undertook to make, and there is the intention you so rashly proclaimed here afterwards that you would raise the siege of Vercelli to-day. Why should you wish to do that if you are not Theodore's friend, if you are not the canker-hearted traitor we now know you to be?'

'If I were to tell you, you would not understand. I should merely give you another proof that I am Theodore's ally.'

'That is very probable,' said Carmagnola with a heavy sneer. 'Fetch the guard, Ercole.'

'What's this!' Bellarion was on his feet even as Belluno rose, and Stoffel came up with him, laying hands on his weapons. But Ugolino da Tenda and another captain between them overpowered him, whilst the other two ranged themselves swiftly on Bellarion's either hand. Bellarion looked at them, and from them again to Carmagnola. He was lost in amazement.

'Are you daring to place me under arrest?'

'Until we deliberate what shall be done with you. We shall not keep you waiting long.'

'My God!' His wits worked swiftly, and he saw clearly that they might easily work their will with him. Of the four thousand men out there, only Stoffel's eight hundred Switzers would be on his side. The others would follow the lead of their respective captains. The leaders upon whom he could have depended in this pass—Koenigshofen and Giasone Trotta—were away at Mortara. Perceiving at last this danger, hitherto entirely unsuspected, he turned now to the Princess.

'Madonna,' he said, 'it is you whom I serve. Once before you suspected me, in the matter of Carmagnola's bridges, and the sequel proved you wrong.'
