He had just handed back the scrap of vellum when several fast-moving horsemen appeared from the direction of Caer-Birrenswark. Artorius muttered, "More bad news, it looks like," an assessment Ancelotis was forced to agree with, particularly when the riders came close enough to identify as soldiers of Galwyddel's cataphracti. When their officer recognized the Dux Bellorum, they drew to a halt to greet Artorius. The man spoke without preamble.
"Have you seen Lailoken, the minstrel?"
A queasy sensation hit Stirling square in the gut as Ancelotis answered. "I spoke briefly with him, some ten miles further back." He gestured down the road that led toward Caerleul.
"Then we may yet catch the bastard. King Medraut sent us to fetch the god-cursed traitor back for trial."
Even as Ancelotis gasped, the Dux Bellorum said in a soft and dangerous voice, "King Medraut? Mean you not Queen Morgana?"
The officer hesitated, clearly upset by that piece of news, as well as whatever disaster Lailoken might have unleashed. The man cleared his throat, then said, "No, it was King Medraut who gave the orders to find the minstrel. The abbot of Caer-Birrenswark himself drew up the agreement to transfer the throne of Galwyddel to Medraut. That news was startling enough, but the lad, er, the new king has also married."
An unhappy look darkened the man's eyes. "It seems utter insanity, but Father Auliffe has lent the support of the Holy Church to Medraut's marriage and I cannot imagine a man less likely to support treason. Medraut has married the heiress to Dalriada, you see, and the abbot swears it is a good alliance with nothing of treachery in either the girl or her father. The hope was to secure the northern border between Strathclyde and Dalriada against invasion. And it might have worked, truly it might, only..." He hesitated.
"Only what?" Artorius growled, eyes dark and grim.
"Only Lailoken has betrayed all of Britain. He's a Saxon agent, in the pay of King Aelle."
"Lailoken, a Saxon spy?" Ancelotis asked, eyes widening in astonishment. "How can that possibly be proved? I've seen the man in my brother Lot's court and he spent a week or so entertaining the soldiers of Caer-Iudeu. You saw him yourself, Artorius, at Rheged's festivals. He's a comic buffoon and a passable minstrel, but a spy?"
The officer nodded, eyes bleak. "A Saxon spy and much else as well, I fear. There is far worse news than Medraut's marriage to Keelin of Dalriada. Lailoken is a poisoner. A monstrous saboteur. While he and Medraut visited Fortress Dunadd to arrange the marriage with King Dallan mac Dalriada, he poisoned the entire city, poisoned the wells, at least that's what Father Auliffe and Queen Morgana suspect. A Briton slave escaped across the border into Strathclyde and rode for Galwyddel with the news that all of Dunadd is dead, down to the infants at their mothers' breasts. Vomiting, convulsions, paralysis—it was no natural plague that killed those poor bastards." Distress roughened the man's voice.
The image struck Trevor Stirling with a familiar sense of horror, even as Ancelotis and Artorius went stiff with shock. Biological warfare was a reality Stirling had witnessed before, in the twenty-first century, but neither the king of Gododdin nor the Dux Bellorum had any experience with such atrocity.
"The whole town?" Artorius whispered. "My God, Dalriada will massacre every Briton in Strathclyde before marching into Galwyddel!"
"Not if we can catch Lailoken and hand him over to the Irish," the officer muttered. "Queen Morgana and King Medraut have taken ship to try and catch Dallan mac Dalriada before he returns home, to try and convince him it was Saxon treachery, not Briton. Queen Keelin and her Druidess have gone with them, to try and prevent utter disaster."
Artorius just shut his eyes. "Oh, God, watch over her," he groaned.
Ancelotis muttered agreement, while Stirling tried to sort out a confusing issue that puzzled him immensely. The murder of an entire town by some form of biological weapon was entirely in keeping with an agent of the Irish Republican Army. But why would Brenna McEgan massacre the Irish? It made no sane sense. The IRA terrorist had come here to further Irish interests, so why destroy the very Irish settlers who were destined to form the political and social structure of the entire Scottish Lowlands?
If McEgan had poisoned Caerleul, or even Artorius, it would have been perfectly understandable. But not Dalriada. And if Brenna McEgan had not killed every soul in the Irish colony's capital, who had? The Saxons? It was difficult to credit such a notion, when the sixth century's natives were completely unfamiliar with the ways in which a whole settlement could be taken out with chemical or biological agents.
Artorius was asking, "And Morgana has already left for Dalriada? You're sure of that?"
The officer nodded. "Father Auliffe said she took sail from the Lochmaben coast, by way of a fishing sloop, trying to catch up with Dallan mac Dalriada's ship."
"Whether or not she succeeds," Ancelotis said quietly, "there is nothing you and I can do to change what will happen between her and the king of Dalriada. All we can do is strengthen the northern garrisons against invasion and turn our own attention to the Saxon threat in the south."
"King Medraut has already ordered riders north to warn Strathclyde of the danger to the border forts. Just in case."
"Then we must ride south," Artorius said heavily. "And pray God the Irish believe her. For myself, I must suspend judgement against Morgana and Medraut until the war with the Saxons has been decided, one way or the other."
"Agreed," Ancelotis murmured, half sick with grief and worry.
They turned their horses about and set out in pursuit of Lailoken. They had gone perhaps three miles when one of the men back in the line of cataphracti broke into song, a stirring, cadence-rich marching tune which brought the hairs on Stirling's arms and nape standing straight up. He drew rein sharply, trying to locate the singer.
"Where did you hear that?" he demanded.
The soldier blinked in surprise. "One of the minstrels was whistling it at Caer-Birrenswark. I hadn't heard it before and asked him to teach it to me. It's good for the riding, don't you think?"
"Oh, yes, it's a snappy little tune," Stirling agreed darkly. "Let me guess? He learned the tune from Lailoken?"
The man stared in absolute shock. "Aye, that's what he said. He'd been to Caerleul and learnt it there, from Lailoken. How did you know? Is it a Saxon tune, then?" the man asked worriedly.
"In a manner of speaking." Stirling was cursing himself as the worst fool ever to put on the uniform of the SAS. All the little clues he had failed to notice before had fallen neatly into place the instant he heard that particular song. It was a marching song, all right. An Orange marching song. One of the Orangemen's favorites, in fact. It wouldn't even be written for more than a millennium and a half. If Lailoken had been singing it, he could have learned it from only one soul: Cedric Banning. The man whose British affectations had struck Trevor Stirling as odd, that first night, the kind of snobbery a status-seeking colonial might display—or a very clever man wishing to pass himself off as one.
And he'd worn a paisley scarf, must have been laughing at Stirling the whole time they'd sat in that pub, wearing such a blatant, insulting clue and watching the SAS officer blunder his way right into the trap Banning had set up. Brenna McEgan hadn't killed Terrance Beckett. Banning had. McEgan must have been planted by the IRA as a countermeasure against an Orange terror plot. The bruises on her face—and on Banning's knuckles—floated into his mind's eye, another humiliating clue he'd ignored. McEgan must have walked into the lab right on the heels of the murder. And Banning, clever bastard, had led Stirling straight down the garden path with that note about her ties to Cumann Na Mbann.
