"I am not reassured," the Northman replied.

"Why, you should be, friend Anders. I am in all things and in all ways the very soul of honesty. Not only do I pride myself on my true and forthright nature, but I believe that I can claim to have never knowingly allowed a falsehood to pass my lips. The slightest deceit is quite beyond my capabilities, and every day I fervently pray to be struck down in the most horrible and grisly fashion imaginable should I fail to live up to my own exacting standards of decent and moral conduct."

"And what is that?"

"Decent and moral conduct? Why, I define-"

"No, no, not that. The most horrible and grisly demise imaginable. What would that be?"

Jack raised his hand as if to answer, thought for a moment, and then lowered it. "I'm not entirely sure." Momentarily nonplussed, he tapped his finger on his chin and then gave up with a shrug. "I'll think on it. Are you satisfied with the arrangements?"

Anders grimaced. "I accept, under one condition: If I end up fighting the demon, I get the fifth gem."

"I assure you, that condition is completely unnecessary," Jack said.

"If that is really the case, then you should be able to agree to it without hesitation. Now, do you agree to my condition?"

Jack winced and offered a weak smile. Anders was much smarter than he looked. "I do, although perhaps we should define 'fighting.'"

"Easily done. If I find myself in a situation where it's trying to kill me, or I'm trying to kill it. Now, if you please, resume your burglary."

The small thief opened the door and slipped out into the hall. He furiously considered some kind of strategy by which he might have avoided conceding the last gem to the Northman but fell short. He glided past several doors emblazoned with the symbol of the House Kuldath, an anvil crowned by five gemstones, and wondered idly if in the near future the brothers would amend their house symbol to a plain anvil. Jack had carefully studied the interior of the building through various divinations and seeing spells over the last week, committing the entire plan of the building to his memory. He knew, for example, that the door immediately to his left led to the personal quarters of Aldeemo, eldest of the brothers, and that the door across the hall led to a linen closet backed by a secret stairway that led down to the emporium on the first floor. Talent in both sorcery and thievery made possible thefts that mundane rogues or honest sorcerers would never have attempted.

He reached the end of the hall, where a door sheathed in green copper sheets warded the upper vault. Here Jack knelt and fished out a couple of small picks from a pouch at his side, expertly picking the lock with a moment's work. He glanced over his shoulder; at the other end of the hallway, Anders peered out of the carpet storeroom, watching intently. Jack winked at him and opened the copper door, quietly sliding inside.

The room was a small, crowded place fitted with five counting desks all in a row, awash in bagged coinage and precarious stacks of iron strongboxes. Had Jack a mind to take it, the coinage itself would have been an epic success… but he was after something more impressive than hundreds of pounds of coins. He worked his way to the back of the room, where a small iron box rested in an alcove in the wall. Cautiously, he inspected the niche and the box, using his poignard gently to raise the front edge of the box.

The weight of the box held down a small spring-loaded trigger, just visible under the center of the container. "Perfectly predictable," Jack muttered. Taking the box out of the niche would trigger some kind of alarm or trap. He could probably disarm it, but did he need too? Suddenly the answer struck him. He laughed softly. "Of course!" Carefully, he fished another set of picks from his pouch and set to work, quickly opening the small box right where it sat. If he didn't move the lockbox, he wouldn't trigger the trap, and that meant that all he had to do was remove the rubies from the box without removing the box from the niche. With one final click, the box opened.

Five perfect rubies glimmered darkly inside.

Jack grinned. He pushed the lid back out of the way, exposing the five rubies to view. Then, as a precaution in case removing the weight of the rubies might be sufficient to trigger the spring-loaded catch beneath the box, he fished out a small wooden dowel from his burglary kit and wedged it in place to hold the box firmly down on the bottom of the niche. That done, he produced a small silk cloth from another pocket and folded the five rubies inside. "And that is that." He grinned.

Something snuffled and grunted outside.

Jack froze. He held his breath, listening intently. Then he mumbled an invisibility spell, fading from sight as the familiar words and energies worked the magic in the accustomed way. Even as he vanished, the counting-room door slowly swung open, creaking on its hinges.

A hulking, bearlike shape stood in the door. Leathery bat-wings flapped and shuffled as it advanced into the room. Demonic red eyes glowed in the center of an ursine face crowned by curling ram's horns.

"Come out, come out, little thief," the demon hissed. Its voice was thick oil poured over a hot stove. "I can smell your magic, I can hear your heartbeat, I can taste your spoor in the air. You cannot hide from me."

Jack decided to try anyway. He held himself perfectly still, breathing slowly and silently.

The demon advanced into the room, snuffling and spreading out its limbs to grope for him. "I see you have borrowed my masters' rubies, little thief," the creature hissed. "Put them back now, and I will allow you to live."

Moving very slowly, Jack crouched low and began to feel his way forward. The only way to escape was to dive under the creature's grasp and bolt before it could turn to follow. He tightened his grasp on the gems, held in his left hand. Then, before he could lose his nerve, he jumped to one side and scrambled under the monster's outstretched paws.

"Anders!" he called.

The demon roared and slammed its monstrous talons against the wall, trying to catch hold of Jack or pin him in place, but Jack dropped to all fours and scrambled past the guardian. Coins glittered and crashed in the darkness. The monstrous creature whirled with impossible speed and sprang after him, talons grasping blindly for him, its stinking breath hot on his neck. Jack gained his feet in the hallway outside and fled for his life.

At the far end of the hall, Anders broke his cover and charged forward, unsheathing his broadsword with a shrill ring of steel. The demon roared and spat a gout of flame at the swordsman, driving him to the ground. For one long, flawless moment, Jack saw nothing between him and his route of escape but the dark crevice of the storeroom door. He put his head down and ran for all he was worth.

Then a door opened right in front of him, and Aldeemo Kuldath stepped right into his path. Pale and wizened, the easterner blinked his eyes sleepily while drawing back the string of a small hand crossbow. Jack, still invisible, crashed into him at a dead run. Both thief and merchant sprawled to the floor. Aldeemo's crossbow fired with a sharp snap, embedding its tiny quarrel in the middle of his own left foot. Jack's rubies flew from his hand and scattered across the polished wood floor of the hallway, skittering and dancing like droplets of wine.

"My foot!" howled the merchant.

"My rubies!" wailed Jack. His invisibility faded, spoiled by the collision.

Roaring in rage, the demon leaped over both to meet Anders's charge, as the Northman shrieked a battle cry and sprang forward with his blade flashing. The guardian's claws and teeth snapped and gouged huge furrows in the paneling. Anders dodged and slashed, parrying the attack and hacking away at the monster with furious strokes.
