It would be the same when he blew up the Senate.
He opened the lime-wood box with an ornately carved hinged lid that sat on his desk. The box had belonged to his father, and Cotta had lost count of the number of times he’d praised the old man’s good sense in keeping it in his bedroom rather than taking it to the west wing when he’d conducted his final experiment in the search for immortality.
Lined up side by side within the box, like dolls in a cot, lay several kid-skin pouches, separating the ingredients for the fabled elixir. Cotta untied the string from one of the pouches, dipped his finger in the ruby red powder and examined it in the light. Realgar. What the Arabs who fetched it up from the bowels of earth called Fire of the Mine. He sniffed carefully, but did not make the mistake of licking his finger, instead wiping it clean with a cloth. Realgar was a form of arsenic.
He retied the pouch, opened another and tipped out a series of opaque yellow crystals, each forming a perfect metallic cube. A third pouch contained crystals of a much brighter yellow. Needle-like, these crystals were sulphur, while yet another pouch kept separate the gritty, vermilion-coloured cinnabar, which the old man had insisted was essential. The final pouch contained the most precious ingredient of all. A substance known as Poseidon Powder.
Poseidon was the name the Greeks gave to the God of the Sea, who conjured up storms and cleaved the land with his trident, sending waves three storeys high to devastate the land after he’d shaken it. Fine and chalky, white as flour, Poseidon Powder was only found in a handful of secret places in the world, one of which lay close to the rose-red city of Petra in the Jordanian desert.
These nitre beds were formed from camel dung from the huge caravans that used to camp outside the city in the old days, before the sands-and the caravans-shifted. Over time, the dung reacted with the salty soil and the moisture in the air to form crystals that dissolved in rain then dried into a fine, white powder on the surface. To the Arabs who guarded these precious nitre beds, the powder was known as salt of Petra. Saltpetre.
For Cotta’s father, this substance was the key to eternal life.
For Cotta, it was the key to releasing the eagle.
In its present form, the powder was not dangerous, but when mixed with other substances, it was-as his father discovered-highly combustible. What Cotta needed to know was the precise formula the old man had worked to.
Only one other person knew the answer. The servant who had helped the old man with his fatal experiment.
A servant who had apparently vanished into thin air.

Julia’s husband, Marcellus, had no idea he was sitting a mere hundred paces from the Arch-Hawk of the Senate, and even if he had, he would have imagined the Senator’s thoughts were concerned more with the burning of Dacian cities and the storming of Scythian fortresses than how a pinch of chalky powder would change the future of Rome. Every afternoon around this time Marcellus took himself off to the library. Not any old library, mind you, though heaven knows there were plenty to choose from. For Marcellus, there was only one library which mattered. The one adjacent to the Temple of Apollo on the Palatine.
The incentives were numerous. The view, for one. The vast spread of the city sprawled away below him, he could watch the ants bustling back and forth across the open plazas. Slaves doubled under the weight of barrels, beams and sacks, children scampering, donkeys plodding along with bulging panniers. He could see litters carrying the rich. Young men carrying the old. In fact, every stratum of humanity passed below him here, and if a man preferred a gentler pace on which to rest his eyes, he only had to gaze across to the rolling hills beyond, or watch the barges being hauled along the banks of the Tiber by patient oxen. On the other hand, if it was excitement that he craved, he could always crane his neck and watch the charioteers practising in the Circus Maximus below, leather chest protectors tied tight around their torsos and helmets to protect them when they fell. Not that Marcellus could see any of those things today. Low, grey clouds obscured the hills and released a relentless shrouding drizzle.
But if the view wasn’t enough to lure a person up the Palatine’s steep embankment, there was the sheer grandeur of the temple itself. The breathtaking colonnades of yellow Numidian marble. Exquisite frescoes, statues, marble busts, not to mention the Great Frieze depicting Augustus’s victory over Antony and Cleopatra’s fleet at Actium. Some of the finest paintings and sculptures the world had ever seen were on display here, many of them precious beyond price, being works by the old masters, but views and artistic splendours were not the motivation behind Marcellus’s daily visits. He didn’t give a hoot about the Greek and Latin archives, either, or the fact the ancient Sybilline Prophecies were stored at the base of Apollo’s bravura statue.
Important men passed through this library. Senators, philosophers, landowners, merchants, shipbuilders, shipowners, shipping magnates. One day might find Marcellus engaged in debate with a tribune, another day with a prefect for the roads. Sooner or later, he reasoned, one of them was bound to shove a co mmi ssion his way.
There were few potential patrons in the library this afternoon, however. Rain invariably kept people indoors and now that the light was fading, there were even fewer. But Marcellus was determined to remain here to the very last, and he was happily whiling away his time on Plato’s treatise on the ‘Janus Croesus, Claudia!’ He picked himself up from where he’d been sent sprawling across the floor and looked around. ‘Did you see what just happened? Some bastard sneaked up behind me and socked me clean off my stool.’
‘You need a shave,’ she said, sucking her knuckles.
Her? ‘What did you do that for?’ he asked.
‘Pleasure,’ she purred.
Marcellus never expected to figure out what went through women’s heads, but come on. What the hell was wrong with Plato? ‘You’ve killed my reputation as an architect, you know that.’
‘If your reputation had any sense of decorum, it would have committed suicide months ago,’ she retorted. ‘Outside.’
‘But-’
‘ Outside.’
Trailing behind her, Marcellus wished he could have felt something other than a stirring in his loins, but by heaven, his sister-in-law was magnificent when roused. Her breasts heaved, her eyes flashed, a curl would spring loose from its hairpin, and although Marcellus would never have obeyed any other woman’s orders, much less trot meekly after them, with Claudia he would jump off the Tarpeian Rock if she asked him.
‘Would you mind telling me what that was all about?’ he hissed outside. ‘I’ll be the laughing stock of the Apollo Library for months.’
A lie. He knew damn well they’d take her for a disgruntled mistress and that, if anything, his stock would soar.
‘How long before it sinks into that thick skull of yours that prestigious patrons aren’t placing contracts with you, Marcellus, because you spend too much time idling it away in this blessed library?’
