Macro did his best to keep his simmering irritation hidden. Cato, meanwhile, continued to ponder the mystery of the missing grain. He went over every detail of the search that he and Macro had conducted at the warehouse, as well as the information he had gleaned from the grain merchants’ guild and the clerk at the offices of Gaius Frontinus. How could so much grain disappear into the city without any apparent trace? It was a maddening puzzle for Cato which vexed him as he polished his kit and spread his cloak and tunics out to dry on the small wooden rack that was set up close to the section room’s compact brazier. Meanwhile, Macro dutifully headed out each evening to carry out his punishment in the latrines at the end of the block nearest the wall of the camp.

At last, on the third morning the storm blew away, leaving a clear blue sky in its wake and the sun soon began to heat the roofs and streets of Rome, sending tendrils of vapour twisting languidly into the air before they dispersed. The people began to emerge on to the streets, and once more the bodies of those who had starved to death or succumbed to an illness in their weakened state were carried out of the city gates in carts to be added to the many hundreds that had been placed in mass graves along the roads leading out of Rome.

Word arrived from the palace that the Emperor and his retinue would set out to inspect the engineering works and the preparations for the spectacle up at the Albine Lake. Burrus gave the command for the Fifth and Sixth centuries to form up and Tigellinus stormed through the barracks bellowing at his men to get their kit and form up ready to march. The soldiers of each section scrambled out, some still fastening chinstraps and buckling on their armour. When the last man was ready Tigellinus called them to attention and then inspected the ranks, pulling his men up on every minor infraction while Fuscius noted the crime and punishment on a waxed tablet. When the inspection was complete Tigellinus moved back and faced his new command, his fists resting on his hips.
