'Mombelli warned me there was danger of it.'

'Where is Mombelli?' Bellarion asked. He stood with Filippo Maria by the canopied bed in a spacious chamber in the northern tower, adjacent to the Hall of Mirrors.

'Mombelli, devil take his soul, left me a month ago, when I seemed well, to go to Duke Gian Maria who desired to appoint him his physician. I've sent for him again to the Duke. Meanwhile some Pavese doctor will be required to give me ease.' He groaned with pain. Then, recovering, rapped out his orders to Bellarion. 'It's a mercy you are recovered, for you are needed at Bergamo. Meanwhile Carmagnola commands there, but he has my orders to surrender his authority to you on your arrival.'

It was an order which Carmagnola did not relish, as he plainly showed when Bellarion reached the camp two days later. But he dared not disobey it.

Bellarion examined the dispositions, but changed nothing. He carried forward the plans already made by Facino. The siege could be tightened no further, and, considering the straits to which Malatesta must be reduced, there could be little point in wasting lives on an assault.

A week after Bellarion's coming there rode into the great camp of green tents under the walls of Bergamo, a weary, excited fellow all splashed with mud from the fury of his riding.

Brought, by the guards who had checked his progress, to Facino's large and handsomely equipped pavilion, pitched beside the racing waters of the Serio, this slight, swarthy, fierce-eyed man proved to be that stormy petrel, Giovanni Pusterla of Venegono.

Bellarion rose from the couch, covered by a black bear-skin on which he had been reclining, and closed the beautifully illuminated copy of Juvenal's 'Satires,' which had been a parting gift from Filippo Maria. His gesture dismissed the Swiss halberdiers, who had ushered in this visitor. The very name of Venegono was of ill omen, and ill-omened was the man's haggard countenance now, and his own announcement.

'I bring evil tidings, Lord Count.'

'You are consistent,' said Bellarion. 'A great quality.'
