He removed his coat and buckled the scabbard around his waist. He took a few steps as an experiment and found that the scabbard slapped against his leg. The thick leather belt hindered access to his revolver holster as well. He tried another position, slipping the scab- bard belt over his shoulder so that the sword hung down by his left side. Then he got back into his coat.

"Planning to do some fencing?" Zavala said. "Maybe. You must admit it beats your army knife." "My knife has a corkscrew," Zavala reminded him. "What about the overgrown bugle?"

"We'd better put it back. I don't want to advertise the fact that I've absconded with the toothpick under my coat."

They carefully replaced the horn the way it was found and moved to the other side of the room, where a map of the world was spread out on the worktable. Austin bent over the map and saw that coastal areas on all the continents were blocked out in red pen. Noted next to each red section was a date and a listing of various species offish. A large star marked the lake site where they had boarded the airship. He drew his finger from the star along a pencil line due east into the North Atlantic. The notation above the line was that day's date.

He straightened and said, "We've got to stop this ship before it gets to the Atlantic. This isn't a test run."

"Fine with me. I might point out that this thing is almost a thou- sand feet long and full of heavily armed thugs who might have other ideas."

"We don't have to take over the whole ship, just the control cabin.'

"Why didn't you say so? It's as good as done."

"Think you can fly this old gasbag?"

"Can't be that hard," Zavala said. "You hit the throttle and point the nose where you want to go."

Despite the casual reply, Austin never doubted Zavala's words. His partner had hundreds of hours under his belt flying practically every aircraft built. Austin tried to picture where they were in the zeppelin. He guessed that they were about midway along the length of the great airship. If they kept moving forward and down, they would come to the control cabin.

They left the room and its strange museum display and followed a maze of passageways totally unlike those they had encountered when they first came aboard. Their surroundings were newer and more functional. They came to a set of stairs leading down. Austin thought they had come to the control cabin, but he changed his mind when his nose picked up a whiff of brine and fish. He was reminded uncomfortably of his first breath inside the Oceanus fish nursery in the Faroe Islands.

He hesitated at the top of the stairs, drew his Bowen, and slowly descended into the blackness below. His ears picked up the sound of motors and bubbling aerators, further convincing him that his fish- nursery theory was correct. He was about halfway down the stairs, when the lights went on and he saw that he had more than biofish to contend with.

Dr. Barker stood at the bottom of the stairs looking up at him, a cheerful smile on his thin face. His eyes were hidden behind dark sunglasses.

"Hello, Mr. Austin," Barker said. "We've been expecting you.

Won't you join us?"

Any inclination to refuse Barker's offer was tempered by the sight of the stone-faced guards who surrounded the man, and the assault rifle muzzles pointed up the stairwell. The touch of a finger on even a single trigger would be enough to reduce Austin and Zavala to their basic molecules. Even more persuasive was the expression on the face of Barker's scarfaced henchman, who had tried on several occa- sions to kill Austin. His liver-colored lips were stretched in a wide grin that told Austin he was still the top target in the man's sights.

"I would be a fool to refuse such a warm invitation," Austin said, as he descended the rest of the way.

"Now drop your guns and kick them over/' Barker said. Austin and Zavala did as they were told. The guards picked the weapons up. One man came over and frisked Zavala. Scarface stepped up to Austin and ran his hands roughly down the front of the leather coat.

"I'm going to enjoy watching you die," he growled.

Durendal seemed to glow red hot against Austin's ribs. "I know a dentist who could do wonders for your teeth," he said.

Scarface stopped his search and grabbed Austin's lapel in a chok- ing hold, only to back off at an order from Barker.

"That's no way to treat our guests," Barker said. Turning to Joe, he said, "You're Mr. Zavala, I presume?"

Zavala's mouth turned up slightly at the ends, and the softness of his dark brown eyes couldn't disguise the contempt in his voice. "And you're Dr. Barker, the mad scientist, I presume. Kurt has told me a lot about you."

"All good, I'm sure," Barker said. He seemed amused as he glanced back to Austin. "Are you gentlemen on your way to a cos- tume ball?"

"Yes, as a matter of fact. If you don't mind, we'll be on our way/ Austin said.

"Don't run off so soon. You just got here."

"If you insist. We'd like to lower our hands, if you don't mind." "Go right ahead, but don't give my men an excuse to kill you on the spot."

"Thanks for the warning." Austin glanced around. "How did you know we were aboard, hidden surveillance cameras?"

"Nothing so sophisticated in this old relic. Purely as a safety meas- ure, we installed sensors around the ship. A light in the control cabin indicated a change in air temperature in the starboard engine- maintenance room. When we went to investigate, we found the hatch open. We thought it was an accident until we noticed that the coats were missing."

"How careless of us." "It's the kind of carelessness that can get you killed. That was a dangerous way to come aboard. If you wanted a tour, we would have been glad to accommodate you."

"Maybe next time."

"There won't be a next time." Barker stepped forward and re- moved his sunglasses, revealing the pale eyes Austin had first seen at the Smithsonian reception. The irises were almost as white as the rest of his eyes and reminded Austin of a venomous snake he had once seen. "You and NUMA have caused me a great deal of trouble," Barker said.

"Your troubles are just beginning," Austin said.

"Brave words for someone in your position. But not unexpected. Umealiq was disappointed when you foiled his plans for you in Washington."

"Umealiq?" said Zavala, who was hearing the name for the first time.

"That's Scarface's real name," Austin said. "It supposedly means 'stone lance.' "

Zavala's lips curled in a slight smile.

"You find something humorous in the situation?" Barker said. "That's funny," Zavala said. "I thought it was Kiolyan for 'seal ma- nure/ "

Scarface's hand went to the ivory knife at his belt, and he took a step forward. Barker stopped him with an outstretched arm. He gazed thoughtfully at the NUMA men.

"What do you know about the Kiolya?"

"I know that the Inuit consider you to be the scum of the Arctic," Austin said.

Barker's bloodless face flushed scarlet. "The Inuit are in no posi- tion to judge. They have let the world think that the people of the north are nothing but a bunch of blubber-chewing caricatures who run around in furs and live in ice houses."

Austin was pleased to see that he could get under Barker's cold skin. "I've heard the Kiolyan women smell like rancid whale blub- ber," he said.

Zavala sensed the opening and joined in. "Actually, they smell worse," he said. "That's why these goons prefer their own male com- pany."
