principality and a strong rule, and after his death his three or four or five sons, in and out of wedlock, all demand by right equal shares, and the law says they should have them. Then one picks off another, to enlarge his portion, and it would take more than law to stop the killing. I wonder, sometimes, what will happen when Owain's gone. He has sons already, and time enough before him to get more. Are they, I wonder, going to undo everything he's done?"
"Please God," said Hugh fervently, "Owain's going may not be for thirty years or more. He's barely past forty. I can deal with Owain, he keeps his word and he keeps his balance. If Cadwaladr had been the elder and got the dominance we should have had border war along this frontier year in, year out."
"This Cadwaladr is the brother it's best not to mention?' Mark asked. "What has he done that makes him anathema?"
"A number of things over the years. Owain must love him, or he would have let someone rid him of the pest long ago. But this time, murder. Some months ago, in the autumn of last year, a party of his closest men ambushed the prince of Deheubarth and killed him. God knows for what mad reason! The young fellow was in close alliance with him, and betrothed to Owain's daughter, there was no manner of sense in such an act. And for all Cadwaladr did not appear himself in the deed, Owain for one was in no doubt it was done on his orders. None of them would have dared, not of their own doing."
Cadfael recalled the shock of the murder, and the swift and thorough retribution. Owain Gwynedd in outraged justice had sent his son Hywel to drive Cadwaladr bodily out of every furlong of land he held in Ceredigion, and burn his castle of Llanbadarn, and the young man, barely past twenty, had accomplished his task with relish and efficiency. Doubtless Cadwaladr had friends and adherents who would give him at least the shelter of a roof, but he remained landless and outcast. Cadfael could not but wonder, not only where the offender was lurking now, but whether he might not end, like Geoffrey of Mandeville in the Fens, gathering the scum of North Wales about him, criminals, malcontents, natural outlaws, and preying on all law-abiding people.
"What became of this Cadwaladr?" asked Mark with understandable curiosity.
"Dispossession. Owain drove him out of every piece of land he had to his name. Not a toehold left to him in Wales."
"But he's still at large, somewhere," Cadfael observed, with some concern, "and by no means the man to take his penalty tamely. There could be mischief yet to pay. I see you're bound into a perilous labyrinth. I think you should not be going alone."
Hugh was studying Mark's face, outwardly impassive, but with a secretive sparkle of fun in the eyes that watched Cadfael so assiduously. "As I recall," said Hugh mildly, "he said: 'Not quite alone!' "
"So he did!" Cadfael stared into the young face that confronted him so solemnly, but for that betraying gleam in the eyes. "What is it, boy, that you have not told us? Out with it! Who goes with you?"
"But I did tell you," said Mark, "that I am going on to Bangor. Bishop Gilbert is Norman, and speaks both French and English, but Bishop Meurig is Welsh, and he and many of his people speak no English, and my Latin would serve me only among the clerics. So I am allowed an interpreter. Bishop Roger has no competent Welsh speaker close to him or in his confidence. I offered a name, one he had not forgotten." The sparkle had grown into a radiance that lit his face, and reflected not only light but enlightenment back into Cadfael's dazzled eyes. "I have been keeping the best till last," said Mark, glowing. "I got leave to win my man, if Abbot Radulfus would sanction his absence. I have as good as promised him the loan will be for only ten days or so at the most. So how can I possibly miscarry," asked Mark reasonably, "if you are coming with me?"
It was a matter of principle, or perhaps of honour, with Brother
