"Only one?" Theebles asked again.

"Would it matter?" Artemis replied, thinking himself clever. "One, two, or three poisoned drinks, the risks remain equal between us."

The fat lieutenant's expression grew sour. "It is a quarter table," he said condescendingly. "A quarter. One in four.

That is the rule. When the top is spun, each of us has a one-in-four chance of sipping the poisoned drink. And by the rules, no more than one glass can be poisoned, no more than one can die."

"Only one is poisoned," Artemis confirmed.

"The poison is that of the Thesali viper, and only the poison of a Thesali viper?"

Artemis nodded. To a wary challenger like the young rogue, the question screamed the fact that Theebles didn't fear such venom. Of course he didn't.

Theebles returned the nod and took on a serious expression to match his opponent's. "You are certain of your course?" he asked, his voice full of gravity.

Artemis did not miss the experienced killer's sly undertones. Theebles was pretending to offer him the opportunity to change his mind, but it was only a ruse. And Artemis would play along. He glanced about nervously, summoned a bead of sweat to his forehead. "Perhaps…" he began tentatively, giving the appearance of hedging.

"Yes?" Theebles prompted after a long pause.

Artemis started to rise, as though he had indeed changed his mind about making such a challenge; Theebles stopped him with a sharp word. The expression of surprise upon Artemis's young and too-delicate face appeared sincere.

"Challenge accepted," the lieutenant growled. "You cannot change your mind."

Artemis fell back into his seat, grabbed the edge of the tabletop, and yanked hard. Like a gambling wheel, the top rotated, spinning smoothly and quietly on its central hub. Artemis grabbed the long lever flanking him, one of the table's brakes, and Theebles, smiling smugly, did likewise.

It quickly became a game of nerves. Artemis and Theebles locked gazes, and for the first time, Theebles saw the depth of his young adversary. At that moment Theebles began to appreciate the pure cunning of merciless Artemis Entreri. Still, he was unafraid and remained composed enough to note the subtle shift of Artemis's eye, the hint that the young man was quietly watching the spinning glasses more intently than he was letting on.

Artemis caught a minute flicker, a subtle flash of reflected light from the table, then a second. Long before Theebles had come to visit, he had chipped the rim of one of the glasses ever so slightly. Artemis had then painstakingly aligned the table and the seat he'd chosen. With every rotation, the tiny chip in the glass would flicker a reflection of the torch burning in the nearest wall sconce-but to his eyes only.

Artemis silently counted the elapsed time between flickers, measuring the table's speed.

"Why would you take such a risk?" wary Theebles asked, verbally prodding the young man's concentration. "Have you come to hate me so much in a few short tendays?"

"Long months," Artemis corrected. "But it has been longer than that. My fight in the street was no coincidence. It was a set-up, a test, between myself and the man I had to kill. And you are the one who arranged it."

The way that Artemis described his adversary, "the man I had to kill," tipped Theebles off to the young rogue's motivation. The stranger in the dusty street had likely been Artemis Entreri's first kill. The lieutenant smiled to himself. Some weaklings found murder a difficult thing to accept; either the first kill, or the inevitable path it had set the young man on, was not to Entreri's liking.

"I had to know if you were worthy," Theebles said, admitting his complicity. But Artemis was no longer listening. The young rogue had gone back to his subtle study of the spinning glasses.

Theebles eased his brake, slowing the rotation considerably. The hub was well-greased-some even claimed there was a bit of magic about it-so the top did not need much momentum to keep spinning at a nearly constant rate.

Artemis showed no sign of distress at the unexpected speed change. He kept completely composed and began silently counting once more. The marked glass flickered exactly an eighth of the circumference from Theebles's chair. Artemis adjusted his cadence to make each complete rotation take a count of eight. He saw the flicker; he counted and as he hit nine, abruptly pulled the brake.

The tabletop came to a sudden stop, liquid sloshing back and forth inside the glasses, droplets of it splattering to the table and the floor.

Theebles eyed the glass in front of him. He thought to remark that the young rogue didn't understand the proper protocol of the quarter table challenge, for the brakes were supposed to be applied slowly, alternately between the opponents, and the challenged party would make the final stop. The fat lieutenant decided not to make an issue of it. He knew that he had been taken, but didn't really care. He'd been expecting this challenge for almost a tenday and had enough antivenin in his blood to defeat the poison of a hundred Thesali vipers. He lifted his glass. Artemis did likewise, and together they drank deeply.

Five seconds passed. Ten.

"Well," Theebles began. "It would seem that neither of us found the unfortunate quarter this day." He pulled his huge form from the chair. "Of course, your insolence will be reported in full to Pasha Basadoni."

Artemis showed no expression, didn't blink. Theebles suspected that the young rogue was hiding his surprise, or that he was fuming or trying to figure out how he might escape this unexpected disaster. As the seconds passed, the young man's continued calm began to bother the fat lieutenant.

"You have had your one challenge," Theebles snapped suddenly, loudly. "I am alive, thus you have lost. Expect to pay dearly for your impertinence!"

Artemis didn't blink.

Good enough for the young upstart, the fat lieutenant decided with a snap of his fingers. As he departed, he thought of many ways that he might properly punish Artemis.

How delicious that torture would be, for Basadoni could not stop Theebles this time. The guildmaster, who by Theebles's estimation had become much too soft in his old age, had intervened many times on behalf of Entreri calming Theebles whenever he learned that the fat lieutenant was planning a brutal punishment for the young upstart. Not this time, though. This time, Basadoni could not intervene. This time, Entreri had certainly earned the punishment.

The first place Theebles went when he returned to his lavish private quarters was the well-stocked cupboard. The antivenin to Thesali viper poison was known to cause great hunger after the poison was introduced, and Theebles had never been one to need much prompting toward food. He pulled out a two-layered cake, a gigantic, sugar-speckled arrangement, decorated with the sweetest of fruits.

He took up a knife to cut a slice, then shrugged and decided to eat the whole thing. With both hands, he lifted the cake for his mouth.

"Oh, clever lad!" Theebles congratulated, returning the cake to the table. "Sly upon sly, a feint within a feint! Of course you knew the effects of Thesali antivenin. Of course you knew that I would run back here to my personal cupboard! And you have had the time, haven't you, Artemis Entreri? Clever lad!"

Theebles looked to the window and thought to throw the cake out into the street. Let the homeless waifs find its crumbs and eat them, and all fall down dead! But the cake, the beautiful cake. He couldn't bear to be done with it, and he was so, so famished.

Instead, he moved across the room to his private desk. He carefully unlocked the trapped drawers, checked the wax seal to be certain that no one had been here before him, to be certain that Artemis could not have tampered with this supply. Satisfied that all was as it should be, Theebles opened a secret compartment at the bottom of the drawer and removed a very valuable vial. It contained an amber-colored liquid, a magic potion that would neutralize any poison a man might imbibe. Theebles looked back to the cake. Would Artemis be as clever as he believed? Would the young rogue really understand the concept of sly upon sly?
