The hum of noise subsided. A Thracian and a myrmillon in a fish-crested helmet circled each other warily. The long day's professional slaughter had begun.

Justinus and I turned away, still intending to resume our seats. Then, coming from the tunnel, we saw a young man, running fast.

"That's Hanno's son. It's Iddibal."

Stung into action, I was the first to waylay him and demand what was wrong. Iddibal seemed hysterical. "It's Auntie Myrrha! She's been attacked-"

My heart lurched. Things were starting to happen. "Show us!" I commanded him. Then Justinus and I took him by an arm each and pretty well dragged him to where he had found his injured aunt.

Sixty

WE SHOUTED FOR a doctor, but as soon as we examined her we reckoned Myrrha was done for. Justinus exchanged a look with me, discreetly shaking his head. We pulled Iddibal away to the side of the tunnel on the pretext of allowing the medical staff space.

"What was your aunt doing here?" I could not remember seeing Myrrha leave her seat. My last sighting had been with Euphrasia, looking like any substantial matron stuck there for the day, with a packet of dates in her well-beringed hand and a large white kerchief shading her pinned and rolled hair.

Staring over my shoulder to where Myrrha lay, Iddibal trembled. We had found the woman lying against the wall of the tunnel near its far exit at the stadium end. She had made no sound since we reached her. There was blood soaking her robe and now spreading on the sandy floor. Somebody had slashed her right across the throat; she must have seen the attack coming and had tried to fend it off. Her hands and arms were cut too. There was even a knife scratch on one cheek. Judging from a long trail of blood spots, she had staggered out here, coming from the stadium, wrapping her marine blue stole around her wounded throat in an attempt to staunch the blood.

Now she was fading fast, though Iddibal had not accepted it. I knew Myrrha would never recover consciousness.

"Why was she here?" I urged him a second time.

"Our novice fighter is being armed in the stadium."

"Why the stadium?"

"For secrecy."

Justinus touched my arm and went to take a look.

"Who's your fighter?" The frightened nephew had gone limp on me. "Who, Iddibal?"

"Just a slave."

"Whose slave?"

"One of her own that Aunt Myrrha had taken a dislike to. Nobody. Just a nobody."

I pulled Iddibal more upright and rammed him back against the wall. Then I loosened my hold on him, to seem more friendly. He was dressed in holiday style, even more colorful than the last time I saw him. A long tunic in shades of green and saffron. A wide belt around it. A couple of finger rings and a gold chain.

"That's a nice chain, Iddibal." Its workmanship looked familiar. "Any others at home?"

Bemused and troubled, he answered numbly, "It's not my favorite. I lost that when all this began…"

"When and how?"

"In Rome."

"Where, Iddibal?"

"I left my best clothes with my aunt when I signed on with Calliopus-" He was still straining to look past me to where a doctor was crouched over his aunt. "After I was manumitted, I found the chain was gone."

"What did your aunt say?"

"She had to assume somebody had stolen it. In fact, the slave we're putting up today was the only suspect; Aunt Myrrha told that to father and me last night when she suggested him for the bout-"

"Theft sounds a good reason to get rid of him, yes." I bet Myrrha had had another motive. I had a filthy feeling about this so-called thief, and what Myrrha really knew about her nephew's chain. I tugged at the one Iddibal was now wearing. "Same style as this, was it? The one you lost in Rome?"

"Similar."

"I may have seen it once."

At that Iddibal roused himself. He must have interpreted my ominous tone. "Who had it?"

"Somebody gave it to Rumex, the night he was killed."

He seemed astonished. "How can that be?"

The doctor attending Myrrha stood up. "She's gone," he called. Iddibal abandoned me and rushed over to the corpse. The doctor was holding out an object he had found among Myrrha's clothing; since the nephew was grief-stricken the man gave it to me. It was a small knife, with a bone handle and straight blade, such as a domestic slave might use for sharpening styli.

"Seen this before, Iddibal?"

"I don't know. I don't care-for heaven's sake, Falco-leave me alone!"

Justinus came back.

"Marcus." He stepped close to talk privately. "They have an area where their novice is being hidden from the public. I insisted they let me see him; he's nothing much. Sitting quietly in his armor, inside a small tent."

"Alone?"

"Yes. But Myrrha went in to speak to him a short time ago. The attendants are outside, playing dice, and took no notice-he was her slave, apparently. They saw Myrrha leave, heading fast towards the tunnel with her head wrapped up. They thought no more about it."

"Did you mention that she had been hurt?"

"No."

"What's the name of their gladiator?"

"Fidelis, they say."

"I thought it might be!"

Iddibal looked up. Tearstained and haggard yet no longer so distraught, he rose from his knees beside the sticken figure of his aunt. "That's his knife," he told me, rediscovering himself. "Fidelis was her interpreter."

My voice must have been grim: "A man of that name ran errands as a messenger in Rome. I have an idea your aunt then used him for something very serious. Iddibal, you aren't going to like this but you'll have to face up to it: I don't believe Myrrha ever paid over any money for your release from Calliopus."

"What?"

"When she heard from you that Calliopus wanted Rumex dead, she offered to do the job you had refused. I think she used Fidelis. He took your lost chain to the Saturninus barracks, to offer as a supposed gift. Rumex let him bring it close, then as he put it on he was stabbed in the throat. Unlike Myrrha who must have been wary today, Rumex was caught off guard. On that occasion the slave was able to kill neatly and take his weapon home."

"I don't believe it," said Iddibal. People never do. Then they think things through.

"Myrrha must have decided Fidelis knew too much," Justinus followed up gently. "So she planned to have him killed in the arena today to silence him."

"Perhaps once he killed Rumex, Fidelis became too cocky," I suggested, remembering his attitude when we met them at Sabratha.

"For some stupid reason, she visited him-perhaps to apologize." Justinus was a nice lad. I thought it more likely that Myrrha had been taunting the condemned slave. "He stabbed her, and she must have been too shocked to call for help-"

"Impossible to do so," I said. "She had set him up to kill Rumex; she was guilty too. She needed to keep that secret."

So, fatally wounded, though perhaps unaware of just how grave her condition was, Myrrha had proudly walked away. She collapsed. Now she was dead.

I was all set to visit Fidelis myself and interrogate the bastard. But Fidelis would keep. He had nothing to tell me, really; I was now sure I knew exactly what he had done, and how he was now being made to pay for his faithful service to Myrrha. From the way Justinus described him sitting quietly, it sounded as though Fidelis himself understood that discovery had come and was resigned to his fate. He was a slave. If he died in the arena, that was only where a trial judge would send him anyway.

I had something else to think about. Somebody walked out towards us and stopped on seeing the body. A female voice exclaimed in cultured but callous tones, "What-Myrrha dead? My word, it looks as if we're set to have a bloody day. What fun!"

Then, Scilla, my ex-client, deigned to recognize me.

"I want a word with you, Falco! What have you done to my agent?"
