My quarry turned downhill. Opposite the west end of the temple was a gate through the steeply stepped sanctuary wall. The usual scrum of guides and statuette-purveyors milled around. Tiring, Statianus had become less sure-footed. He knocked into a hawker, spilled his tray of votive clay miniatures and was held up in a furious argument. Seeing me catch up, he shoved the hawker into me. I grabbed the man, spun him out of my path, and felt my ankle give as I turned it on one of the scattered statuettes. Cursing, I took my eyes offStatianus and lost him.

He must have gone through the gate. I followed, though doubt gnawed. The path outside led to the legendary Kastalian Spring. Its waters were used in the Delphic rituals, so pilgrims on the full guided tour were dragged here for a sample. Dazed by a mixture of exhaustion and mystic awe, they bumbled everywhere, completely oblivious to anybody wanting to get past them. This really slowed me up. An elderly lady sitting on a rock at the roadside insisted on asking me how far the spring was, trying at least three broken languages when I failed to answer.

The spring rises in a wild ravine. It must once have been a peaceful, rocky haunt of lizards and wild thyme. Now crass voices resounded as visitors washed their feet in the sacred torrents, calling out to their friends how cold it was. Steps led down to "a rectangular basin where seven bronze lions' heads set in clean-cut stone slabs spouted water which was collected by touts with little drinking cups, all eager to obtain a tip, assuming visitors had any money left after purchasing the stickman statues, tacky tat, and crumbling votive cakes. I bet when the pilgrims had gone on their way, the shrine parasites just collected the goodies from the handily positioned niches and sold them again.

I scanned the people, searching for Statianus. By now, I myself felt like a barley cake that had been left too long on a ledge in the sun. A cup-pedlar tugged my sleeve. I jerked away.

I stood on the roadway, thinking I had lost him. Breathing hard, I startled a few pilgrims as I gazed out at the mountains and swore at the scenery.

Then I saw there was a second fountain. Older and almost deserted, this one had a small paved courtyard with benches around it on three

sides. Here, just four rather friendly looking old bronze lions spewed water in hiccupy trickles, while a solitary attendant lurked, without much hope. I bought a cupful, dashed it down, and tipped him.

"Seen a man out of breath?'

Amazingly, he waved an arm. I thanked him and set off once again, heading further down the path. Almost at once I heard Helena behind me, calling. I slowed. She caught up, and we continued together, jogging through shady olive groves until we passed the Delphi gymnasium. Beyond it lay a small enclosed sanctuary which had an air of immense age.

We slowed right down. We glanced at each other and walked into the sanctuary. Altars with inscriptions against the retaining wall told us we had come to the long-revered sanctuary of Athena Pronaia. Apart from the clutch of altars, it had just five or six main buildings, arranged in a line, including a large abandoned temple which had been destroyed by an earthquake. A newer, smaller temple had replaced it. There were a couple of treasuries, fronted by a large pedestal bearing a trophy. In the centre of the site stood a beautiful circular building, surrounded by Doric columns, with exquisite decoration on its upper features, of the type called a tholos. We had seen one at Olympia, where Philip of Macedon and Alexander the Great had collected statues of themselves and their ancestors. This stood on a circular base of several steps. Collapsed on these, struggling to recover his breath, was a young man in a white tunic.

We walked across to him.

"Tullius Statianus!' Helena's voice was hoarse but she sounded strict and determined to stand for no nonsense."I believe you know my brother, Aelianus.'

He looked up with dull eyes, unwilling or unable to run away from us any longer.

We took him to the gymnasium. It was close by, a familiar place where Statianus might relax; and it was bound to have food-sellers. Helena found a place in the shade outside (since as a woman she was barred, while I set us up with pastries, stuffed vine leaves, and olives. Statianus ate most of it. He seemed ravenous; I wondered if he had run right out of money.

Spending cash, I mean. He must possess funds, but out here he could be stranded. Men of his rank only need a banker abroad who knows their banker in Rome, but without such a contact they are as helpless as the rest of us. Delphi would have money-changers, but since the shrine's decline there would be few international financiers who took letters of credit. Statianus was said to be bad at managing and once he had used up what was in his pouch, he could find himself stuck.

Now we took a proper look at him. He was probably clean but he needed a shave. Under the stubble, his face was devoid of character. He had a limited range of expressions. he could look up, down, to the left and to the right. His mouth never moved and his eyes had no animation. A kind person would say grief had wiped him out. I was never that kindly.

Helena and I finished eating first. As Statianus ravenously continued, Helena began the softening up process, first asking about Aelianus. Between mouthfuls, Statianus told us how they had become friends at Olympia. Aulus seemed to have expertise in tragic situations and persuaded Statianus to trust him. He sympathised with the way Statianus had been hounded by the quaestor during the investigation into Valeria's death. When the group were taken to Corinth and put under house arrest, Statianus could not bear to face Aquillius again; he despaired and decided to bunk off to Delphi as a last resort. Aulus tagged along.

"So where has he gone? Why did he leave you?'

"I don't blame him. He thinks this is a waste of time. There's

nothing to do here except wait, month after month, while the organisers at the temple give out the questions, always to other people. Aulus said my connections aren't good enough ever to get a chance at the oracle. But I can wait. I do a bit here at the gym. Sometimes I run.

"Yes, we know you can run!' I snarled wryly."You use the training tracks here at the gym?' The sports facilities were on two levels, with a washing area between them. The lower building appeared to be a palaestra, with the usual large courtyard and side rooms for boxing practice. When I bought the food I had seen that the upper building had an indoor covered running track for use in hot or otherwise inclement weather, with an open-air colonnade at the back; both tracks extended a whole stadium's length."Aulus is pretty athletic. Did he practise with you?'

"Yes, but being stuck here bored him. He tried to persuade me to abandon the oracle, but I am adamant. I need the gods' help to find out what happened to my wife.'

A raw note had entered his voice. We let him alone for a few minutes. Eventually Helena took him back to the beginning of his marriage, asking how Valeria had been chosen as his bride. Statianus confirmed that prior to the wedding the couple hardly knew each other. Valeria's mother had been a friend of his own mother's years before.

"She was respectable, but she came cheap?' My frankness grated. Statianus steadied, as if he recognised he was up against a fiercer interrogator than he had encountered so far. Aquillius Macer had stubbornly thought him guilty, but lacked push; even Aulus would go easy on a fellow aristocrat – he rarely used charm, but had a snobbish politeness with his own level of society.

Impatient with my rudeness, Helena leaned towards Statianus."We met your mother in Rome. She is thinking about you, missing you. She wants you to come home and be taken care of
