Knox tailed Peterson to a high wall with a neat row of well-spaced date palms standing like sentries in front. Fatima's Hermopolis compound, as he'd expected. He kept a good distance behind, but even so Peterson may have sensed something because he suddenly whirled and glared into the darkness. Knox froze, trusting the deluge to hide him. Peterson turned forwards again, reached the main gate, oil lamps fluttering weakly either side, a sign inviting visitors to ring the bell. But Peterson had no intention of doing that. He hurried past, reached the end of the wall, turned down the side, splashing over the waterlogged sand, looking for another way in. The back gate was evidently locked from the inside and wouldn't open. He completed a full circuit, paused in the shelter of a date palm. After a few moments' reflection, he wedged his boot between the wall and the tree-trunk, lifted himself up, looked over the top to make sure there was no one there, that he could drop down safely on the other side. He hooked a leg over the top, straddled it, lowered himself down before letting go and landing with a splash and a grunt and a clatter. But then only silence.
Knox considered ringing the front bell, raising the alarm. Peterson would have one hell of a time explaining himself. But it wouldn't be a picnic for Knox either; and he couldn't risk getting banged back up in gaol. So he wedged his foot like Peterson had done, grabbed hold of the top, hauled himself over. Peterson had had a minute's head start, but Knox had local knowledge. He took a short cut between the lecture hall and kitchens, reached the courtyard with the sleeping quarters. All the lights were off, but he spotted Peterson beneath an awning when he turned on a pocket torch to consult his print-outs, work out which was Gaille's bedroom. Something clattered inside the kitchens. There was a muffled curse. A cry of exasperation went up. 'Stay where you are,' yelled a man, as doors flew open all around the courtyard. 'Put your hands on your head.' An ambush. Peterson turned and fled, all the policemen chasing after him, shouting orders, waving torches, leaving Gaille's French windows tantalizingly open.
Knox hurried forwards in out of the rain, shoes squelching on the terracotta tiles. Her laptop was open on her desk. He yanked out its leads, packed it into its case, slung it over his shoulder, was making for the French windows when he heard footsteps, saw the beam of a flashlight. He dropped to the floor, rolled beneath the desk. Two policemen came in, stomping their feet. 'Tonight it rains,' grumbled the first. 'Nothing but sun for six damned months, and tonight it rains like the world's on fire.'
'I'd better call our friend in Alexandria,' grunted his companion. 'He'll want news.'
'Not this news,' muttered the other. 'I think he'll…' He trailed off. Knox noticed the glazed slug's trail of mud he'd laid on the floor, leading directly to him. He sprang out from beneath the desk, startling the policemen, barging between them, out through the French windows into the courtyard. Other policemen were returning bedraggled and empty-handed from their chase. Knox ran the other way, towards the rear of the compound. The back gate was bolted top and bottom. The top bolt slid easily but the bottom one was stiff. He had to jiggle it before it would open. Footsteps splashed behind him. Torch-beams picked him out. He hauled the door towards him but it clogged on the bloated earth. He squeezed through but it snapped closed again, snagging the laptop so that he had to twist it sideways to pull it free. But then he was out in the desert, laptop slapping his backside as he ran.
The rain continued to hammer. He glanced back. Torches flashing, people shouting. A low fence ahead, he hurdled it in one stride, but his feet slid from beneath him on landing. Lightning illuminated an SCA sign as he picked himself up, trousers sticking wetly to his legs. He headed towards it, looking for anything familiar; conditions had been very different on his last visit. He heard gates open. An engine roared, headlights sprang on full-beam, casting his shadow out ahead, making the fat raindrops glint like jewels. He foolishly glanced around, ruining his night vision, then clattered headlong into a protective railing, tumbled over it, clinging on to avoid falling into a pit, hauled himself to safety. A ladder was tied to the wall. He climbed down into darkness, fumbling in vain for some way out.
A vehicle pulled up above. Doors slammed, people shouted. A torch shone down, briefly illuminating a corridor to his left. He hurried down it, blindly feeling the walls, the ancient windows and niches in them informing him he was in the animal catacombs. He twisted and turned, looking upwards for a glimpse of the sky, a ventilation shaft through which he could escape. Torchlight ahead. He turned back. Light that way too.
He felt the walls, found a window, climbed through it into a cell, half-filled with debris and sand. An eerie place, made all the more so by the fluttering approach of a torch. A mummified baboon stared glassily from a niche in the far wall. Baboons had been revered around here as the personification of Thoth, Egyptian god of writing, associated by the Greeks with Hermes, which was how Hermopolis had got its name. Hundreds of thousands of baboons had been buried in these catacombs, which stretched for miles.
Heavy wheezing outside, the rasp of a lighter, the orange pulse of a cigarette. Knox pressed himself against the wall. A man's backside appeared in the mouth of the cell as he sat down to enjoy a smoke.
