Fundanus’ firetrap of a stable finally decided to go up in smoke? Either way, the responsibility fell on him, for the vigiles were constabulary and fire brigade both.

He threw open the door. Just as he had expected, there stood the panting figure of Larcius Afer, who had the watch that night. “Well, what is it?” Tero demanded, adding hopefully, “I don’t smell smoke.” The siphon, which was the city’s chief fire-fighting implement, was a pain in the fundament to deploy and use.

“No, sir,” Afer agreed. He paused to wipe sweat from his face. The night was warm, and he had plainly run some distance. Tero, who was not the most patient of men, glared at him until he continued. “Clodius Eprius has been killed.”

“What do you mean, killed? Has he been murdered?”

“Killed, sir,” Afer repeated stolidly. “Kleandros is with the body now. He’ll be able to tell you more than I can, I’m sure.”

“Obviously,” Tero snapped. Still, he was glad the Greek doctor would be there. They were old friends, though they argued constantly.

The tesserarius ducked back into his house for sandals, then accompanied his fellow vigil to the dead man’s home. It was a couple of hours before dawn, and a waning crescent moon shed a wan light over the town. Nevertheless, it was dark enough to make Tero glad his companion carried a torch.

Eprius lived (or rather, had lived) at the opposite end of town from Tero’s home. He and Afer tramped through Vesunna’s central forum, silent save for the sound of their footsteps. At its very heart was the temple dedicated to the city’s tutelary gods. Its huge circular cella made it currently the biggest structure in Vesunna, but the amphitheater being built not far away promised to dwarf it and everything else in the town.

Tero wondered idly what the old Petrocorii, the Celtic tribe that had founded Vesunna, would have thought of such an incredibly huge edifice. Magic, without a doubt: Anything was magical to someone who did not know how to do it.

His thoughts turned back to Eprius. Why would anyone want to kill the old fool? Tero knew him fairly well, and also knew he had not a single enemy in town. Had some footpad done away with him? Tero tried to pump Larcius Afer, but Afer shook his head, saying, “You’ll have to see for yourself. “With a small shock, the tesserarius realized his subordinate was frightened. That was very strange. Before settling in Vesunna, the two of them had served together on the Rhine, and Tero knew full well that the skirmishes there had thoroughly inured Afer to the sight of gore.

It seemed as if most of Eprius’ neighbors were gathered outside his front door. Well, Tero thought, that’s scarcely surprising. They all started talking at once when they saw him, raining questions down on his unprepared head. “I don’t know a damned thing yet,” he said, pushing his way through the crowd. “If you’ll let me by, maybe I’ll find out something.”

Kleandros met him at the entrance. Tero liked the sharp-tongued physician. They had worked together before, and once or twice a month they would meet for wine, a friendly game of draughts, and much good talk. Still, the doctor’s elegant slimness always made the squarely built Tero feel like a poorly trained dancing bear. Just by standing before him, Kleandros made him suddenly and acutely aware of his own uncombed hair, the patches and stains on his cloak, and the ragged bit of leather hanging from one sandal. As usual, he disguised his feelings with raillery. “Hello, quack,” he said. “What do you have for me today?”

An opening like that would normally make Kleandros sputter and fume, but today he did not rise to the bait. Under the curling black ringlets he combed low on his forehead, his face was grim as he answered, “Hello, Tero. I’m glad to see you. You’d best come look for yourself.” He was speaking Greek instead of Latin, something he did only when very upset. Tero began to worry in earnest.

The physician led him down the dark entry hall to the dining room. Someone had refilled and lit all the lamps there; the flames cast multiple dancing shadows. Three couches had been grouped together in one comer of the room. One was overturned, and the wall behind it bore a sinister stain. The vigil looked a question at Kleandros, who nodded. “Poor Eprius is behind the couch,” Kleandros said. “Tell me what you make of him.”

“Why me? You’re the doctor,” Tero said, but he walked around the couch.

Both on the Rhine and as a vigil in Vesunna, Gaius Tero had seen the results of more violent deaths than he liked to remember. Yet the corpse in this quiet room shook him in a way none of the others, however grisly, ever had. He was in the presence of the unknown, and little fingers of ice crawled up his back as he viewed its handiwork.

Eprius’ body lay on its right side; its right hand still clutched a stick. Tero barely noticed, for his gaze was fixed in horrified fascination at the ruin that had been its head. There was a neat hole about the width of Tero’s little finger over the left eye. A small stream of blood ran down over Epirius’ face to join the pool beneath his head. Already flies were beginning to buzz about it.

Bad as that was, it was far from the worst. Whatever had drilled through Eprius’ forehead had smashed out through the back of his head, tearing his skull open: Much of the left rear quadrant of his head was a sickening soup of brain, pulverized bone, scalp, and hair. It was that which had stained the wall; blood cemented the gory fragments to the plaster.

The hobnails of Larcius Afer’s sandals clicked on mosaic tiles as he came up. Dread was on his face; his fingers writhed in a sign to avert evil. “It was Jupiter’s thunderbolt that slew him.” Afer said. “Two or three of the neighbors heard him cry out, and then the terrible roar of the thunderbolt itself-and not a cloud in the sky. His man Titus had the evening free and when he got home, he found this.”

Tero had never been one to fear the gods unduly, but he felt the little hairs on the back of his neck trying to rise as he listened to Afer. Surely nothing in his experience could have produced the ghastly wound he saw. To have Kleandros throw back his head and laugh was unbelievable. Tero wondered if the doctor had taken leave of his senses, and Afer stared at him indignantly.

“How many men has either of you known to be killed by the gods?” Kleandros demanded. “I’ve been a doctor for twenty years now, and I’ve never seen one yet.”

“There’s always a first time,” Afer said.

“I suppose so,” Kleandros conceded. “But Clodius Eprius? Good heavens, man, use your head for something more than a place to hang your hair. The worst thing Clodius Eprius did in his whole life was to drink so much wine friends had to carry him home. If the gods started killing everybody who did that, why, there wouldn’t be five men left alive in the empire by this time tomorrow. No, I’m afraid that if the gods left it to Nero to kill himself and soldiers to do away with Caligula, they wouldn’t have much interest in Clodius Eprius.

Afer was still far from convinced. “What did kill him then?” he demanded.

“I haven’t the slightest idea right now, but I intend to find out instead of moaning about Jupiter.”

The physician’s healthy skepticism gave Tero the heartening he needed to shake off his superstitious fear and begin thinking like a vigil once more. He quizzed Eprius’ neighbors, but learned nothing Afer had not already told him. There had been shouts and then a crash, but nobody had seen anyone fleeing Eprius’ home. Titus proved even less informative than the neighbors. He was grief-stricken and more than a little hung over. When Eprius had given him the night off, he had not questioned his master, but headed straight for the wine and girls of Aspasia’s lupanar, where he had roistered the night away. When he came back and found Eprius’ body, he rushed out to get Kleandros, and that was all he knew. Tero left him sitting with his head in his hands and went back to the dining room.
