The inkvine scar along his jawline writhed as he turned, casting a smile across the room.

"So you don't even have a good morning for me, you young imp," Halleck said.

"And what barb did you sink in old Hawat? He passed me in the hall like a man running to his enemy's funeral."

Paul grinned. Of all his father's men, he liked Gurney Halleck best, knew the man's moods and deviltry, his humors, and thought of him more as a friend than as a hired sword.

Halleck swung the baliset off his shoulder, began tuning it. "If y' won't talk, y' won't," he said.

Paul stood, advanced across the room, calling out: "Well, Gurney, do we come prepared for music when it's fighting time?"

"So it's sass for our elders today," Halleck said. He tried a chord on the instrument, nodded.

"Where's Duncan Idaho?" Paul asked. "Isn't he supposed to be teaching me weaponry?"

"Duncan's gone to lead the second wave onto Arrakis," Halleck said. "All you have left is poor Gurney who's fresh out of fight and spoiling for music." He struck another chord, listened to it, smiled. "And it was decided in council that you being such a poor fighter we'd best teach you the music trade so's you won't waste your life entire."

"Maybe you'd better sing me a lay then," Paul said. "I want to be sure how not to do it."

"Ah-h-h, hah!" Gurney laughed, and he swung into "Galacian Girls." his multipick a blur over the strings as he sang:

"Oh-h-h, the Galacian girls

Will do it for pearls,

And the Arrakeen for water!

But if you desire dames

Like consuming flames,

Try a Caladanin daughter!"

"Not bad for such a poor hand with the pick," Paul said, "but if my mother heard you singing a bawdy like that in the castle, she'd have your ears on the outer wall for decoration."

Gurney pulled at his left ear. "Poor decoration, too, they having been bruised so much listening at keyholes while a young lad I know practiced some strange ditties on his baliset."

"So you've forgotten what it's like to find sand in your bed," Paul said. He pulled a shield belt from the table, buckled it fast around his waist. "Then, let's fight!"

Halleck's eyes went wide in mock surprise. "So! It was your wicked hand did that deed! Guard yourself today, young master -- guard yourself." He grabbed up a rapier, laced the air with it. "I'm a hellfiend out for revenge!"

Paul lifted the companion rapier, bent it in his hands, stood in the aguile, one foot forward. He let his manner go solemn in a comic imitation of Dr. Yueh.

"What a dolt my father sends me for weaponry," Paul intoned. "This doltish Gurney Halleck has forgotten the first lesson for a fighting man armed and shielded." Paul snapped the force button at his waist, felt the crinkled-skin tingling of the defensive field at his forehead and down his back, heard external sounds take on characteristic shield-filtered flatness. "In shield fighting, one moves fast on defense, slow on attack," Paul said. "Attack has the sole purpose of tricking the opponent into a misstep, setting him up for the attack sinister. The shield turns the fast blow, admits the slow kindjal!" Paul snapped up the rapier, feinted fast and whipped it back for a slow thrust timed to enter a shield's mindless defenses.

Halleck watched the action, turned at the last minute to let the blunted blade pass his chest. "Speed, excellent," he said. "But you were wide open for an underhanded counter with a slip-tip."

Paul stepped back, chagrined.

"I should whap your backside for such carelessness," Halleck said. He lifted a naked kindjal from the table and held it up. "This in the hand of an enemy can let out your life's blood! You're an apt pupil, none better, but I've warned you that not even in play do you let a man inside your guard with death in his hand."

"I guess I'm not in the mood for it today," Paul said.

"Mood?" Halleck's voice betrayed his outrage even through the shield's filtering. "What has mood to do with it? You fight when the necessity arises --

no matter the mood! Mood's a thing for cattle or making love or playing the baliset. It's not for fighting."

"I'm sorry, Gurney."

"You're not sorry enough!"

Halleck activated his own shield, crouched with kindjal outthrust in left hand, the rapier poised high in his right. "Now I say guard yourself for true!"

He leaped high to one side, then forward, pressing a furious attack.

Paul fell back, parrying. He felt the field crackling as shield edges touched and repelled each other, sensed the electric tingling of the contact along his skin. What's gotten into Gurney? he asked himself. He's not faking this! Paul moved his left hand, dropped his bodkin into his palm from its wrist sheath.

"You see a need for an extra blade, eh?" Halleck grunted.

Is this betrayal? Paul wondered. Surely not Gurney!

Around the room they fought -- thrust and parry, feint and counterfeint. The air within their shield bubbles grew stale from the demands on it that the slow interchange along barrier edges could not replenish. With each new shield contact, the smell of ozone grew stronger.

Paul continued to back, but now he directed his retreat toward the exercise table. If I can turn him beside the table, I'll show him a trick, Paul thought.

One more step, Gurney.

Halleck took the step.

Paul directed a parry downward, turned, saw Halleck's rapier catch against the table's edge. Paul flung himself aside, thrust high with rapier and came in across Halleck's neckline with the bodkin. He stopped the blade an inch from the jugular.

"Is this what you seek?" Paul whispered.

"Look down, lad," Gurney panted.

Paul obeyed, saw Halleck's kindjal thrust under the table's edge, the tip almost touching Paul's groin.

"We'd have joined each other in death," Halleck said. "But I'll admit you fought some better when pressed to it. You seemed to get the mood." And he grinned wolfishly, the inkvine scar rippling along his jaw.

"The way you came at me," Paul said. "Would you really have drawn my blood?"

Halleck withdrew the kindjal, straightened. "If you'd fought one whit beneath your abilities. I'd have scratched you a good one, a scar you'd remember. I'll not have my favorite pupil fall to the first Harkonnen tramp who happens along."

Paul deactivated his shield, leaned on the table to catch his breath. "I deserved that, Gurney. But it would've angered my father if you'd hurt me. I'll not have you punished for my failing."

"As to that," Halleck said, "it was my failing, too. And you needn't worry about a training scar or two. You're lucky you have so few. As to your father --

the Duke'd punish me only if I failed to make a first-class fighting man out of you. And I'd have been failing there if I hadn't explained the fallacy in this mood thing you've suddenly developed."
