Rome. I stayed at his shoulder. He introduced Arica and Tibullinus, whom he knew. Tibullinus appeared to be the man in charge. He was a truculent, untidy centurion; and I didn't like him much. With them was Porcius, a young recruit of Petro's who had been formally attached to them as an observer. He lost himself among the rest of the Sixth's enquiry team rather rapidly.
While we were going through the formalities, another couple of horses turned up. Their riders slid down, then they too joined us, openly nodding to Petro.
'What's this?' cried Tibullinus, sounding annoyed, though he tried to hide it. 'Checking up? On the Sixth?'
'Far be it from me to slander the meticulous Sixth!' Petro assured him. He was a devious bastard when he chose. 'Just a couple of lads I told to lend a hand when they'd finished something else. Looks like they only just caught up with you ..
Everyone realised his couple of lads had attached themselves to the Sixth and their not-quite prisoner for the whole journey - and that the men of the Sixth had failed to notice they were being tagged. They should have known, it could have been any kind of ambush. We left it at that, before things became too sensitive.
Something was about to happen.
There was a moment's unnatural atmosphere, then everyone straightened and grew watchful. The carriage door creaked as it opened. Then Balbinus emerged.

Always the same shock: you come face to face with a murderous master criminal, and he looks like a ribbon-seller.
Balbinus Pius was five feet three digits - definitely not tall. He was looking me in the windpipe, and appeared not to notice that most of the officers present overstripped him by almost a foot. He had an oval head; an expressionless face; wavering eyes; an anxious expression that verged nicely on bewilderment. His manner was quiet; no more threatening than a ladybird.
His hunched shoulders held up a dapper white tunic and short grey cloak. The cloak was pinned extremely neatly on the left shoulder by a round gold brooch set with five garnets. He had healthy pink skin. On the top of his head it was visible through the short, thinning down of near-baldness; the bushier stuff above his ears had been lathered with some discreetly piquant lotion. He wore dark grey leather travelling boots. His seal ring was gold, a Greek design of a winged female driving a four-horse chariot. He wore two others for ornament, one set with sapphires and ovals, the other openwork, cut from sheet gold with added granulation. He wore the plain wide gold band of the middle rank. He carried no weapons.
I was annoyed, and so was Petro, that Tibullinus, Mica and some of the other men of the Sixth stepped forwards and shook hands with him, bidding farewell. Words were exchanged. Unable to tolerate it, the rest of us looked away and breathed disapproval. We were reluctant to become part of the conversation. We were resisting being coerced. We had glimpsed the complacency amidst which corruption flowers.
'How can you do that?' Martinus spluttered at Arica; Arica had actually slapped Balbinus on the back, as if he were seeing off his own cousin to the army. Martinus always spoke his mind.
'No harm being polite.' The Sixth had been supervising Balbinus' movements ever since he went to trial. Contact would have been unavoidable.
The whole group of the Sixth began standing back now that they had delivered the package to us. As soon as he saw them shaking hands with the criminal, Petronius Longus had abandoned any pretence that this was a joint mission. His normal easy-going manner had vanished; I had never seen him so serious. The rest of the climax belonged to him and to the Fourth. Once the Sixth had formally taken their leave, they slunk from the scene.
I said nothing, but I had a sense that Petro's night of triumph had just been spoiled.
The freedmen had taken all the luggage on to the ship. They stayed aboard. We could see sailors assuming their places at the mooring
