It was entirely possible that she had been part of that terrorist group. It was also entirely possible that she was innocent of everything Stirling—and London—had suspected of her. And Cedric Banning had excellent reason to poison an entire Irish city. Stirling wondered who, exactly, had tipped off London that an IRA mole had infiltrated the lab staff? Banning himself? Trying—with embarrassing success—to divert attention from his own agenda? It hardly mattered, now that the damage had been done.
The question of how he'd done it was answered shortly enough. Moving at a steady gallop, they covered the remaining miles rapidly, only to discover that their quarry was no longer on the road. He had bolted, abandoning his packhorse, which they found grazing at the verge of the Roman highway, snatching up greedy mouthfuls of grass. A search of the horse's panniers brought to light several wine bottles and ceramic jars, all carefully stoppered, with the corks and sealed lids bound down with twists of heavy twine.
Artorius held one of the glass bottles up, peering curiously at the lumps visible inside. "It looks like chunks of meat and rotten vegetables."
"Don't open any of them!" Stirling warned sharply, seeing all too clearly how Banning had committed the atrocity at Fortress Dunadd. Botulism toxin. He felt an utter and complete fool, with no way to undo the damage already wrought. Damage which might well have destroyed Stirling's entire future, with no way to tell until the equipment shut down at the end of a year—and no guarantee that it even existed any longer, to be shut down. From this end of history, there literally was no way to tell.
Worse, yet, was the damage Banning could still do. Using botulism, the man could literally poison every Irish town and farmhold from Londonderry to County Kerry and further south, to Cork. All he'd need was a cover story—and what better cover than a traveling minstrel, bringing news of a marriage of alliance between Dalriada and Galwyddel? He wouldn't even have to mention it had ended in treachery, since no one in his wake would survive long enough to find out differently.
Stirling had to shut his eyes against the vision of all Ireland dying, leaving the island wide open for Saxon invasion. Banning was an Orangeman and the Orangemen were descended from pure Anglo-Saxon stock. An Orangeman could take no better revenge than to utterly annihilate the entire Irish population, while simultaneously stirring up war between Dalriada and Galwyddel—at a time when his Saxon ancestors were laying waste to the entire south of England. Divide British attention between war at both ends of the island and the Saxons would conquer it all, the entire British Isles, in one fell swoop. Frosting on the cake would be a few bottles of death emptied into the wells of strategically important Briton strongholds.
The question was, which way had Lailoken and his unseen guest bolted? West, to Ireland? To spread the word of alliance and treachery, while quietly leaving mass murder in his wake? Or south, to join his Saxon kinfolk and take to Aelle and Cutha the secret of biological warfare contained in these monstrous little bottles?
In low, terse tones, Stirling told Artorius as much as he could, without compromising Ancelotis' status as his host. Artorius listened in black silence, then spat to one side.
"We'll have to split our forces, meager as they are. Two riders west, toward the coast, two east, in case he's bolted for Dewyr, as Cutha did. The rest of us will ride south, toward Caer-Badonicus. And pray God we catch him before he reaches his paymasters."
Staring utter disaster in the face, whichever way Lailoken had bolted, they mounted their war-horses in silence and set out in grim pursuit.
Dawn's first hint of oyster light had touched the eastern sky when one of the sailors who'd climbed the mast to act as lookout spotted sails dead ahead.
"I see them!" he shouted, pointing. "He's landward of us, rounding the tip of Kintyre!"
Morgana's heart lurched into her throat and Brenna gripped the gunwale, fingers turning white in the crepuscular light. At her side, Keelin clutched Medraut's hand and braced herself against the wild pitching of the boat as the captain turned the tiller, sending them on a tack that would take them on a shorter and faster route, seaward of the longer, looping journey Dallan mac Dalriada's crew had chosen, keeping closer to land. The Irish king's sails rose up out of the sea as they narrowed the gap, plowing deep into the troughs while the sails rattled and snapped taut again on the new course.
Brenna wished mightily for a pair of radios or even a signal cannon to flag the other ship's attention and was too distraught to try and explain to Morgana what either device was, much less how they worked. As they drew steadily closer, Brenna realized the only thing that had allowed them to catch up was the lighter, smaller boat they rode in, much faster across the water than Dallan mac Dalriada's larger and heavier warship. Like the Greeks at Salamis, whose smaller, faster boats had wrecked the massive Persian navy, the Briton fishing sloop rapidly overtook the Irish ship, finally drawing within shouting distance as they both rounded the tip of the Kintyre Peninsula.
Riona Damhnait had already taught the sloop's captain the words to shout, as deeper male voices carried farther across water than women's voices ever could. The captain bellowed out the message, which drew startled reactions from the Irish crew. A moment later, they had dropped a sea anchor overboard, slowing their speed enough to match pace with the slower Irish ship. Dallan mac Dalriada appeared at the ship's rail, shouting a question across. Riona answered, shouting as loudly as she could, while the sailors of both craft flung ropes across, snugging the ships together and running burlap bags filled with sand over the sides to act as bumpers, so the hulls didn't grind one another to splinters.
"Help me across, Medraut," Morgana said, swallowing down nausea that had very little to do with the wild pitching of the deck under their feet. "And help your bride and Riona, as well."
A moment later, all four stood on Dallan mac Dalriada's deck, while Keelin flung herself into her father's arms and sobbed out their awful news. The Irish king washed white with shock, holding his daughter tightly while he flung questions at his Druidess. Riona spoke rapidly, urgently, hands sketching gestures in the cold, wet dawnlight as she relayed the message which had come by way of the young Briton slave. His face clouded over with black rage as he listened. When he snarled some order, sending his men toward the Britons, weapons drawn, Keelin flung herself into Medraut's arms and spoke shrilly, nearly hysterical in her effort to stop whatever her father had just ordered. Given the black looks the crew sent their way, neither Morgana nor Brenna McEgan had any illusions as to the nature of that command.
Keelin braced herself at bay, arms thrown wide to protect Morgana and Medraut, like a wild vixen run to earth and snarling at the hounds who snapped at her helpless kits. Even Riona stared in surprise at the violence of the girl's response to Medraut's abrupt danger. What Medraut did next sent Morgana's heart plunging straight into the sea. He unslung his sword and dropped it onto the wet deck, took Keelin gently by the shoulders, and lifted her aside. He then stepped forward and faced the wild-eyed king straight on. Without turning his gaze away from Dallan mac Dalriada's for so much as a half-second, he said to Riona Damhnait, "Please tell my father-in-law that I will gladly die by his hand, if it is his will. But my death will accomplish nothing, not even vengeance, if he attacks Britain and allows the true culprits, the Saxons, to escape unscathed, laughing in their beards at blind Irish rage."
