Arthur looked at Merlin, who looked back. Neither of them could think of a reason to keep Ganelin out of the investigation. Arthur put a hand on the boy’s shoulder. “Yes, of course we want you to help. But you must remember, Ganelin, you have other duties as well. You are still my squire.”

“I won’t neglect my duties, sir.”

“And you must promise to share everything you learn with Merlin, and to do so immediately. He is in charge of this investigation.” He looked around the table. “That goes for the rest of you, too.”

There was a general murmur, though neither Britomart nor Mark seemed happy about it.

“Promise me, all of you.”

They did so, one at a time.

“I don’t want any of you working alone. Whoever did this is vicious, maybe even mad.”

“Like Pellenore?” Brit said, voicing her suspicion.

“Pellenore?” Arthur frowned, obviously not liking the thought. “He’s a harmless old fool.”

“Is there such a thing as a harmless fool? In the town where I grew up there was a fool, a complete imbecile, who used to go wild when he saw the gleam of precious metal. How do we know Pellenore isn’t the same?”

“He’s been here for years, Brit. We’d have noticed by now.”

“There isn’t much point to us investigating if you’re going to reject possibilities out of hand, Arthur.”

He took a deep breath. “I know it.”

“Pellenore left the Great Hall before the ceremony got under way. He was galloping about the castle as usual, screaming about bogeymen. And in his day he was a warrior. He knows how to handle a broadsword.”

“Why not let us investigate,” Merlin interjected, “and bring our results to you? We could spend the whole day spinning theories. But we need facts.”

Arthur took a deep breath. “I want all of you to be careful. This is a killer, after all, and possibly a madman. Don’t let anyone know you’re investigating.”

“When we start asking questions,” Brit said, “they’ll know.”

“We must never ask directly what we want to know.” Merlin was in teacher mode. “We must be clever. Indirect. We must learn what we want slyly, carefully.”

Arthur turned thoughtful. “Exactly. And-suppose this. Suppose I make an announcement that Mark is conducting an official investigation in my name? He will conduct one for show, and that will leave the rest of you to do the real work.”

“Am I in, then?” Ganelin sounded quite unsure of himself.

“Yes, Ganelin. You are one of us.” Merlin smiled. “And I’m certain you’ll be a great help.”

“Good. I mean, thank you. If I might say something…?”

“By all means, Ganelin.” One of the ravens flapped to Merlin’s shoulder, and he stroked its head.

“Well, sir, it seems to me you’re making some assumptions that might not be valid.”

Mark laughed. “Oh really? What are they?”

“Be quiet, Mark.” Brit shushed him impatiently.

“Well…” Ganelin looked uncertainly around the room. “You’re assuming the criminal must have been after the skull and the shrine and the king’s sword out of greed. Is that necessarily so? And you’re assuming it must be someone who left the Great Hall.”

“He can hardly have committed the crime while he was still there.” Mark laughed again. Merlin crossed the room to him and took the wine cup firmly, pointedly, out of his hand.

“No, sir,” Ganelin went on. “He-or she-couldn’t. But there were certainly people who simply never went to the hall.”

Everyone looked at one another, startled and abashed that it hadn’t occurred to them.

“I mean, unless someone was keeping a roll of who attended, that is.”

“You’re right, Gan.” Brit seemed pleased he had thought of it. “Everyone who matters-everyone who is anyone- was at the hall. We think. But-”

“It’s the kind of thing the servants will know, if anyone does. As I said, I can be a help to you all.”

“I don’t think there’s any doubt about that at all.” Arthur glared at Mark, warning him not to make any sarcastic comments. Then he took another cup of wine and drained it in one swallow. “I have to go. I have to preside at court today. There are sure to be peasants squabbling over livestock. I have such important matters to judge.”

They all bade him good morning, and he left. Mark took his wine cup again. Everyone in the room turned to Merlin.

“It seems we have several clear suspects.” Ticking them off on his fingers, he went on. “Morgan and her party, especially Mordred. Guenevere and hers, particularly Lancelot. Pellenore. But there must have been others who left the hall before Borolet was-before the crime happened. And as Ganelin rightly suggested, there may be key people who simply avoided the ceremony. We need to find out who.”

Nimue had been listening, taking everything in. “I’m fairly certain I saw Gawain heading for an exit.”

“Good observation. Did anyone else notice anything?”

“That damned Frenchman, Accolon. He left.” Mark had never trusted him.

“Good. And anyone else?”

They stared at one another blankly.

“I think we have to assume there must be one or two more.” He turned to Ganelin. “Can you ask among the servants, then, and see if they can tell us where any of the suspects were? And whether there are any others?”

“Of course. I’ll be happy to. Give me a day or two, all right?”

“That will be fine. Meanwhile, the rest of us can begin to question the various possible culprits. Obliquely, indirectly. We don’t want anyone to know we’re investigating.”

“People will guess.” Mark sounded impatient with it all. “A crime has been committed at Camelot. At the seat of government. That makes it much more serious than any ordinary murder. Whatever the motive, this strikes at the heart of England’s government and stability. We must find the assassin and bring him to justice as quickly as possible.”

“Of course, Mark.” Brit was finding him annoying. “I’m sure we all share those concerns. They must have occurred to each of us. Until we find the killer, Arthur himself is in danger, and so is everyone else at court.”

Mark started to bicker with her, but Merlin got between them and dismissed the little council. “Thank you all for coming. I’m sure Arthur is grateful to have us working together. ” He hoped his point wasn’t lost on Mark. Then he gestured to the window. “We’re lucky in one way, at least. Look-more snow. From the look of the black clouds in the west, another storm is coming, possibly worse than the one last night. If I’m right, no one will be leaving Camelot for at least a few more days.”

“Splendid.” Mark slammed his cup down on the table and got to his feet. “More of this damned overcrowding. I’m sharing my quarters with two elderly knights from Dover. They smell of flounder.”

“It is a gift, Mark. Let us take it and use it to our advantage. ”

Mark scowled and stomped out the door. For the hundredth time Merlin found himself wishing Arthur’s knights wouldn’t drink so heavily. He asked Brit if she had anything more to add, but she said no and left. To Nimue, she said, “Thanks for the wine, Colin.” She said it with a wink, and Nimue looked at Merlin as if to repeat, She knows about me.

Ganelin lingered by the door. He seemed to be screwing up his courage. “May I ask you something, Merlin?”

“Yes, of course.”

“Well, why can’t you just use your magic powers to divine who did the-who-who did that to my brother?”

Merlin rolled his eyes skyward. “I am not a wizard, a magician, a sorcerer, a shaman, a warlock or anything else of that sort. When am I ever going to convince people of that?”

“All the knights say you are. They say for anyone to be as wise as you-to know as much as you do about so many things-is unnatural. It could only come from something dark, something hidden.”

“The knights are fools, most of them. And drunken fools at that. What they don’t understand, they make mysterious. But reason-understanding-is the key to every mystery. Even your brother’s death. You’ll see.”
