Uncertain, unhappy, she got into the carriage with Brit, and the column left Camelot.

Then Merlin headed to the castle library, where one of the copyists was working on something for him. “Good morning. Is it ready?”

“Nearly, sir.” The copyist was a slender young man in his late twenties. “It’s simple enough.”

“Fine.”

“Are you certain you don’t want any illuminations or enhancements? It’s so plain.” He wrinkled his nose. “Unattractive. I can do better work than this.”

“Just a plain, straightforward copy of the chart, please, with no crosses, triangles and such.”

“Yes, sir. It will be ready in an hour or so.”

“Fine. Bring it to me then, will you? I’ll be in my tower.”

Next he went to Arthur’s tower and found Greffys. “I should be ready this afternoon. You’ve explained to the servants what I want?”

“Yes, Merlin. But-”

“But what?”

“They’re suspicious.”

“Who wouldn’t be? But they must understand that we’re investigating the murders. And they must understand that they themselves are not under suspicion. Tell them that. Reassure them. I’ll do the same when I talk to them.”

“Yes, Merlin. I thought you wanted the investigation kept secret.”

“The time for that is past. I think we should be ready to begin by mid-afternoon. Bring the first of them then.”

“Yes, sir.”

“And Greffys?”

The boy had turned to go; he paused in the doorway. “Yes?”

“You’ve done a fine job so far.”

The squire beamed. “Thank you!”

And so at mid-afternoon Greffys brought the first of the servants to Merlin’s study. She was one of the kitchen girls, a buxom redhead in her early twenties. And she was plainly nervous.

“Good afternoon.” Merlin smiled in a way he hoped was fatherly and reassuring. “You are Alice?”

“Yes, sir.”

“Has Greffys, here, explained why I want to talk to you?”

“Yes, sir.”

“Good. You understand, my only interest is in the informationyou might be able to provide. No one thinks you’ve done anything out of line.”

“Yes, sir.”

“Excellent.”

“Yes, sir.”

“Uh… yes.”

“Yes, sir.”

“Do you remember the night of the ceremony for the Stone of Bran?”

“Yes, sir.”

“The night Borolet was killed?”

“Yes, sir.”

“Can you say anything besides ‘yes, sir’?”

“Yes, sir.”

He sighed. “You recall that night, then?”

“Yes, sir.”

“Where were you?”

“Sir?”

“When we all gathered in the Great Hall, where were you?”

“In the kitchen, sir, making honey cakes.”

“As I remember it, the supply of those ran out early.”

“Yes, sir. They didn’t tell us there would be so many people. I-”

“That’s all right, Alice. When you were finished with your duties, where did you go?”

“I-I had to go to the loo, sir.”

“And did you see anyone on your way there?”

“Yes, sir.”

“Who?”

“I saw Morgan le Fay’s son.”

“Mordred? Where did you see him?” He unrolled the copy of Ganelin’s chart. “Here. You see-this is the Great Hall and all the corridors that lead from it. Can you show me where you were when you saw Mordred?”

“Yes, sir.” She squinted at the chart; she seemed to be working to remember. Then she extended her index finger and pointed. “Here.”

“Did he say anything to you?”

“He asked me how to get to the-to the privy.”

“I see.”

“So I gave him directions and he went off-in the wrong direction. He was so lost. He was so cute.”

“I don’t believe I’ve heard anyone else describe him that way. Did you see anyone else in the hall?”

“No, sir.”

“I see. Fine. Thank you very much, Alice.”

She stood, made a shy curtsy, turned and left.

Merlin got out the original chart. The spot where she’d painted was almost exactly where Ganelin had marked one of his little stars. It looked as if Merlin’s guess had been right. Each ★ represented a place where someone had seen Mordred.

The carriage and its escort made good time on the journey to Cornwall. The weather was sunny and dry and the roads were good. They stopped at Winchester for a midday meal. Brit said she knew the town and one particular inn where the food was always good. Accolon, who was again in charge of the escort, posted soldiers outside the inn.

Nimue and Brit had not talked much in the carriage. Their mutual distrust was obvious and getting worse. Brit in particular conversed in monosyllables, and only when it was necessary. Nimue tried making chat about the weather, the countryside, anything she could think of to try to break the ice, but to no avail.

Over lunch she decided she’d had enough. “Do you really think this sullen silence is going to help us do what we have to?”

Brit took a bite of her roast beef almost aggressively. “I don’t know. But I can’t think of any reason why I should trust you, Colin.” She said the name with emphatic contempt.

“Merlin trusts me. Isn’t that what matters? He told you himself he’s the one who has encouraged me to continue this pretense.”

“I’ve been suspicious of you from the outset. From the day you arrived at Camelot.”

“What did you suspect me of? No crimes had been committed then.”

“No, but I find it impossible to trust someone whose identity is such a complete mystery.”

“You know who I am.”

“And if I’ve been suspicious, don’t you think other people must be? Your involvement in this investigation puts us all at risk.”

“I don’t see how.”

“Never mind.” Unhappy, Brit called to the innkeeper for more meat. A few minutes later they were back on the road.

Greffys brought more and more of the servants to Merlin for interrogation. And one session after another went much like the first one had gone. Some of the servants were talkative and cooperative; some were silent or nearly so, sullen and distrustful.

They had been in the hallways for various reasons- hunger, restlessness, nature’s call. Some of them had seen one or more of the suspects; most had not. But one fact emerged clearly from the first several interviews-none of them had seen anyone in the halls who might make a plausible suspect except the suspects who were already known to him. Mordred, Pellenore, Lancelot. So far he had found no one who’d seen Mark.

Then one of the stable boys claimed to have seen him. As before, Merlin showed him the copy of the chart and asked him to indicate where. The boy pointed precisely to a spot where Ganelin had marked an X on the original. “You’re certain of this? It was King Mark of Cornwall that you saw?”

“Yes, sir. I know him. I’ve groomed his horse for him.”

“And this is the spot?”

“Yes, sir.”

“And you told Ganelin about this? He questioned you?”

The boy nodded.

“Very well. Thank you. You may go.”

“Uh… sir?”

“Yes?”

“Ganelin told me my information was valuable.”

“And so it is.”

“He said you’d give me a farthing.”

“Oh.” Scowling, Merlin found his pocketbook, got out a coin and gave it to the boy. “Thank you again.”

“Anytime, sir.” Beaming, he left.

So Mark was the X. There seemed less and less room to doubt it.

But Greffys was puzzled by it all. “Excuse me, sir, but I thought King Mark was a friend of King Arthur.”

“The Hebrews have a holy book called Micah, Greffys. One of the things it says is ‘A man’s enemies are the men of his own house.’”

“But-but didn’t Arthur come to power with Mark’s help?”

“That would be a politic way of putting it. As a young man Arthur became determined to unify England. Until then it was a patchwork of tribes and confederations, all of them at each other’s throats all the time. Arthur realized that England would never progress-would never advance to par with the rest of Europe-until some kind of unity could be imposed.”

The boy seemed bewildered by this.

“Look, Greffys, there is power here. We have the population and-thanks to the Cornish tin and wine-the economic clout to stand shoulder to shoulder with any country on the Continent. We are only beginning to see the benefits that come from a unified nation, but they are real, and they will grow.”
