t.i.tus was right. All the men from Rhakotis were running for home. A red column of soldiers, so far away it looked stationary, was marching through the enclosure. 'Landed by boat, Falco.'

The way the waves beat against the Pharos base, that could not be easy. I was surprised they had arrived here so quickly, but of course t.i.tus took the credit for his dextrous signalling.

'You're whacked, Falco. You'll do no more good tonight. Tell us who the other fellow is, and let the military track him down.

Those words seemed as sweet as a lullaby.

LI.

Even the worst nights end eventually. So, although my head still thronged with images of dark figures gesticulating against towering flames, I awoke to the hard clear sunlight that for several hours had been streaming through an open shutter. It must be mid-morning, maybe later. Subdued murmurs told me that my little daughters were close by, playing quietly on the floor together. When I had had adventures, they would often creep up near me while I recovered. I lay for a while, drowsily fighting wakefulness, but then let out a grunt to tell Julia and Favonia they could now scramble on to the bed with me. Helena found us all cuddled up together when she brought a tray of food for me. One arm around each, I kissed the children's soft, sweet-scented heads and gazed at Helena like a guilty dog.

'I am in disgrace.'

'Was it your fault, Marcus?'

'No.'

'Then you are not in disgrace.' I smiled at my tolerant, wise, forgiving girl with all the adoration I could muster. As smiling goes, it was fervently meant, though perhaps rather pallid. 'Don't do that again,' she added waspishly. ' - Ever!' Ever!'

I remembered that I was delivered home by soldiers, filthy and exhausted. I thought it had been in the dead of night, though Helena reckoned closer to dawn.

'You were sensible enough to order people to look for Pastous at the Library. He was found safe, incidentally. A message came from Aulus. Aulus is coming here later, to see what needs doing.'

She propped me up on cushions while I ticed down a late breakfast. I had little appet.i.te. I let the children steal most of it. Helena perched on a stool, watching without comment. When I pushed away the tray and slumped wearily, she told the girls to run off to see Albia, then we two settled down alone to catch up on all that had happened.

I tried to narrate the story logically, to make sense of it myself.

Helena listened, her great dark eyes thoughtful. It all took time. My words came sluggishly. Left to myself I would have lain still and closed my eyes again.

No use. I had to decide what to do.

'So... where are Fulvius and Pa?'

'They went out, Marcus.' Helena appraised me. I must look a wreck, but she was cool, clean, beautiful in garnet reel and a russet stole. Her face seemed pared and hollow, but her eyes were clear. Although she wore no cosmetic tints, she had dressed her fine hair meticulously, holding it in place with a full pantheon of long ivory pins, topped with little G.o.ddesses. Her custom was to be carefully groomed after I had had a sc.r.a.pe - to remind me that I did have someone worth coming home to. 'I had told them you got into trouble in a bar... they believed it very readily. Perhaps you should buff up your reputation, dearest.' She spoke as a long-term partner discussing work, rea.s.serting her own importance. I knew that att.i.tude. It posed no threat. Her sniping tone would be temporary. 'I believe they are hoping to meet Diogenes.'

'He won't turn up!' I shifted about; every joint ached. I found it impossible to get comfortable. 'The military will try to keep a lid on what happened - the Pharos is remote enough, but there were members of the public all over the place. Rumours will leak out.'

'Well, when you came back last night, I rushed down and took over. I have done my best to hide what happened.'

Helena had been magnificent: alarmed, naturally, she pretended to be coping with a reprobate husband; shooed everyone else back to bed. I had heard her rapid enquiries of my escort, their sheepish answers. I remembered her scanning me for wounds, or possibly wicked women's perfumes.

That made me smile at her, a long, deep smile of rea.s.surance and love. Accepting it, Helena hauled herself from her stool, and came across to me. After moving the tray to a side table, she took our daughters' place in my arms, as we held one another for comfort, reconciliation and relief. Once it would have led to more. I was too exhausted; she was too pregnant; we were too intrigued by our enquiries. We lay there, thinking. Don't sneer until you've tried it.

Aulus turned up. He said he had told Pastous to go into hiding - it was either that or protective custody. The fish restaurant where we ate lunch the other day had rooms for hire; Pastous was now secretly staying there. I gave Aulus directions and cash for reward purposes, then sent him across the city to recover the cartload of scrolls that Diogenes abandoned in the street last night. Albia went with him for the adventure.

'I warn you, the man took it into his head I was entrusting him with p.o.r.nographic literature.'

'I wonder why he would believe that?' mused Helena.

I went to the baths as soon as they opened, then spent the rest of the morning at home. Once I would have bounced back faster, but I had reached an age when a whole night of strenuous activity - not not the kind involving women - left me in deep need of recovery time. I consoled myself that Egypt was famous for its sensual baths and exotic ma.s.seurs - only to find that the baths near my uncle's house had nothing better to offer than a miserable washing-slave from Pelusion, who slathered me in sickly iris oil then gave me a half-hearted neck ma.s.sage while he endlessly told me his family problems. It had no effect on my aches and made me utterly depressed. I advised him to leave his wife, but he had married her for her inheritance, which due to the complicated Egyptian inheritance laws, where property was divided between all the children, came to thirty-three two-hundred-and-fortieths of their building. the kind involving women - left me in deep need of recovery time.

'Nevertheless, trust me - leave your wife and get a dog. Choose one who has his own kennel, then you can share that and live with him.'

It went down badly.

Chewing gloomily on a quid of papyrus he sold me, I crawled home to Helena. She met me in the courtyard with a warning that the old men had come in; they had gone into a huddle upstairs. Ca.s.sius had told her they had heard that Diogenes was in a coma, in military custody, and it was certain he would not live. Before they could tackle me, I commandeered the palanquin and fled. Helena came with me; we set off for the Museion.

LII.

Philadelphion was gazing at a herd of gazelles, perhaps trying to seek solace in the company of animals. Gazelles were not the best choice; they grazed in a s.p.a.cious enclosure, indifferent to his mournful scrutiny. Occasionally they would stiffen, heads up. then bound away from imagined danger. He simply continued to stare across their pasture.

We dragged him away, chivvying briskly. I was in no mood for melancholy.

'Leave me alone, Falco. I've already had that centurion down here, making my life dreadful.'

'He told you one of your staff died last night at the Pharos?'

'It was Chaeteas. I identified the body. Since his cousin seems to have gone missing, I shall take responsibility for a funeral...'The man who had seemed so competent and restrained when he conducted the necropsy - when was it? - only six days ago - had sunk into unexpected misery.

Helena and I led him in a quick march to his office. Philadelphion halted outside, as if reluctant to enter this scene of so many conversations and experiments, shared with his two a.s.sistants. 'I had known them since they were boys. I taught them all I knew...'

'So you cannot explain why they were roving through the city in chase of Diogenes yesterday?' Helena asked gently.

The handsome, silver-haired man looked at her sadly. 'No idea. Absolutely no idea . . . 'No idea. Absolutely no idea . . . This business is incredible.' This business is incredible.'

'It was all too real at the time!' I growled. 'Get a grip. I want to know what they had against the trader.'

'I know very little about him, Falco -'

'What would Chaereas and Chaeteas have to do with a scroll-seller?' Losing patience, I shoved Philadelphion on to a stool and loomed over him. 'Look, man - enough people have died in murky circ.u.mstances at the Museion! First your madcap pair were implicated in Sobek's release -'

'Oh that was merely carelessness. They had their minds elsewhere - Roxana saw them standing by the crocodile enclosure talking together so earnestly they were not thinking properly about fastening the locks.'

'Talking about what?' Helena asked.

She deliberately used a mild tone and the Zoo Keeper answered, 'Their grandfather.' Immediately he looked as if he regretted it.

'He had died? I remembered we had been told they were at a funeral, shortly after the Sobek tragedy. 'They were upset?'

'No - no, Falco, they had not learned about their grandfather at that time -' Philadelphion was flapping his hands, apparently torturing himself.

I gave him a slight shake. 'So what were they discussing so intently? Did the gorgeous Roxana eavesdrop?'

'No, of course not.'

'Still,' Helena helped me put on pressure, 'I think you know what the conversation was about. You must know what was troubling Chaereas and Chaeteas. You had a long relationship with them. When they had a problem, they would bring it to you.'

'This is very difficult,' Philadelphion whimpered.

'We understand.' Helena soothed him. Fortunately for him, I was too weary to wring his neck. 'I suppose they told you in confidence?'

'They had to; it could have caused a great scandal . . .Yes, Helena Justina, you are correct. I know what was troubling my a.s.sistants - and troubling their grandfather.' Quite suddenly Philadelphion straightened up. We relaxed. He would tell us the story.

At his best once again, he kept it succinct. Elements of this story sounded familiar. The two cousins' grandfather was a scholar who had been working m the Great Library; once, un.o.bserved, he overheard the Museion Director arranging to sell library scrolls privately to Diogenes. The grandfather took the story to Theon, who had an inkling already of what was going on. Theon attempted to dissuade Philetus, with no success. Then Theon died. The grandfather was at a loss what to do, so he turned to his grandsons for advice.

'Chaereas and Chaeteas told him to report it to you, Falco.'

'He never did so.'

'But you know?'

'I found out myself. I really could have used this grandfather's testimony,' I complained. 'Who is he, or should I say, who was he?'

Philadelphion looked astonished. 'Why he was Nibytas, Falco! Nibytas was my a.s.sistants' grandfather.'

By this point, I was half expecting it. 'Nibytas? The ancient scholar, who died in the Library of old age?'

Philadelphion pursed his lips. 'Chaereas and Chaeteas convinced themselves it was not old age that killed him. They were certain he was murdered - killed at his table by Diogenes to stop him speaking out.'

'Evidence?'

'None.'

'Dodgy!'

Philadelphion agreed. 'I was sure they were wrong. They agitated for me to conduct a necropsy, but - as I believe you know, Falco - the body was too decomposed. The funeral had to be held the next day; mummification was impossible.'

'So what form did burial take?'

'Cremation.' d.a.m.n. 'Only solution,' Philadelphion told us tersely. As a man who lived with animals, he was unsentimental. d.a.m.n. 'Only solution,' Philadelphion told us tersely. As a man who lived with animals, he was unsentimental.

We were all silent, then, as we thought about those two bereaved men: how Chaereas and Chaeteas must have become increasingly disturbed, going over what they believed had happened to Nibytas and fretting that n.o.body else, not even Philadelphion, would help them to expose the truth. I wished they had consulted me. Instead, they conspired to exact revenge themselves. Hence the way they chased down Diogenes last night - and his real fear of them, because he undoubtedly knew why they had come for him.

If they were wrong, the two cousins had driven a man to his death prematurely. Diogenes may have been engaged in criminal activities, but we had laws to deal with that. Chaeteas himself had died on the tower pointlessly. Chaereas, who presumably knew about his cousin's fatal fall, was now a fugitive.

'Where may Chaereas have gone?' asked Helena. Philadelphion shrugged.

'They had connections in Rhakotis? Or would he flee to the desert?' I persisted.

'To some family farm, more likely,' Philadelphion now replied sadly. 'He will hide up until he believes you have left Egypt and the matter of the scrolls has been resolved.'

'He could give a statement,' I barked. 'Chaereas could ensure that his grandfather and cousin did not die in vain. What Nibytas overheard would be third hand, but it could weigh the balance against Philetus. He is slippery and powerful -'

'Undeservedly powerful!' That was Helena, who had no tolerance for greed. 'Will you tackle Philetus, Marcus?' That was Helena, who had no tolerance for greed. 'Will you tackle Philetus, Marcus?'

I shook my head. 'I want all my lines clear first.'

The Zoo Keeper volunteered, 'Philetus knows what has happened to Diogenes.'

I could live with that. It might panic the b.a.s.t.a.r.d. With Pastous in safe hiding and me keeping mum about my last night's adventures, the Director would struggle to discover details. He would not be sure just how much of his malpractice was known. Soldiers were looking for the box-maker, using what I could remember about his whereabouts. They would also search for the second cartload of scrolls, while Aulus had, with luck, now retrieved the first. I would quarantine Fulvius and Pa. The Director was about to find himself very much alone.

'I'll come to Philetus as soon as I am ready. Let him sweat.'

LIII.

Next, I wanted to see Zenon. Helena was tired, feeling the weight of her pregnancy and delayed effects of her anxiety about me yesterday. She stayed sitting on a shaded bench in the gardens, gently fanning herself, while I went up to the observatory alone. I climbed the stairs very slowly as my thighs and knees protested about yet more mountaineering. It would take me days to recover. I was hoping the astronomer would be pleasant and not try anything physical.

As I concentrated on my climb, the light was blocked out. A huge man was coming down towards me. I paused politely at a landing. The last time I squeezed past a stranger on a flight of stairs, it was Diogenes; that thought now gave me goose-pimples.

'Falco! Why, it is Didius Falco! Do you remember me?' Why, it is Didius Falco! Do you remember me?'

Not a stranger. Instead, a terrifically overweight figure; I looked up and recognised him. Worldly, sophisticated and just a touch devious, he must be the largest doctor practising anywhere in the Empire - all the more ironic since his method was to recommend purges, emetics and fasting.

His name was Aedemon. After twenty years addressing the putrefying innards of credulous Romans, he had agreed to be recalled to his home town, to serve on the Board of the Museion. At the meeting we went to, we had heard he was coming. It must be a genteel retirement for a well-respected professional. He could teach occasionally, write learned papers in staccato medical prose, revisit friends and family he had not seen for years and criticise from a distance the bad habits of his former patients.

After exclaiming over this chance meeting with genuine pleasure, Aedemon's next remark was that I looked in need of a laxative.

I felt a big grin spread across my face. 'Oh it makes a change, a wonderful change, Aedemon, to meet an academic with a practical att.i.tude!'

'The rest are whimsical slobs,' he agreed at once. Helena and I had liked him. 'They need me to line them up and dispense wild lettuce and common sense.'

I gave Aedemon six months, then the inertia and in-fighting would wear him down - but I did trust him to have a good stint first.

We were still on the stairs. Aedemon had wedged his tremendous backside against the wall for support while we chatted. I hoped that wall was well built. 'What were you doing up aloft, doc? Do you know the starry-eyed Zenon, or did he call you for a consultation?'

'Old friends.Though his yellow bile needs correcting. I want him on a strict regime to cure that choler of his.'

'Now listen,' I said. 'I trust you, Aedemon - so tell me, please, can I trust Zenon?'

'Absolutely straight, 'Aedemon responded. 'His bodily humour means he is p.r.o.ne to bad temper - but equally, he is of impeccable moral virtue. What did you suspect he had done?'

'On your say-so - nothing!'

'Well you can trust him with your life, Falco.'

'He tried to throw me off the roof I reported mildly.

'He won't do it again,' Aedemon a.s.sured me. 'Not now. I've put him on a regular decoction of myrrh to cleanse his rotting intestines - and I am about to prepare his personal regime of ritual chants.'

This mystic lore hardly fitted with the pure science that Zenon had always protested, but friendship can overturn many barriers.

'He will be farting too much to lose that temper, 'Aedemon confided in me - with a rather wide grin.
