Nora looked back at him.
“That was Leng’s grand project: to rid the earth of humanity, to save mankind from itself, from its own unfitness. He was searching for the ultimate poison—hence those rooms full of chemicals, plants, poisonous insects and reptiles. Of course, I had plenty of tangential evidence before: the poisonous materials on the glass fragments you unearthed from Leng’s old laboratory, for example. Or the Greek inscription on the escutcheon outside the house. Did you notice it?”
Nora nodded her head numbly.
“It’s the final words of Socrates, spoken as he took the fatal poison. ‘Crito, I owe a cock to Asclepius; will you remember to pay the debt?’ Yet another thing I should have realized sooner.” He cauterized another vein. “But it wasn’t until I saw the room full of weapons that I made the connection and realized the scope of his plans. Because creating the ultimate poison alone wasn’t enough—he would also have to create a delivery system, a way to make it reach across the globe. That’s when the more vexing, inexplicable parts of the cabinet—the clothing, weapons, migratory birds, windborne spores, and the rest—made sense to me. Among other things, while researching this delivery system, he had collected all manner of poisoned objects: clothing, weapons, accessories. And much of it was poisoned by himself—redundant experiments with all manner of poisons.”
“My God,” Nora said. “What a crazy scheme.”
“It was an ambitious scheme, certainly. One he realized would take several lifetimes to complete. That was why he developed his, ah, method of life extension.”
Pendergast put the electrocauterer carefully to one side. “I’ve seen no evidence here of any supplies for closing incisions,” he said. “Clearly, Fairhaven had no need of them. If you’ll hand me that gauze and the medical tape, I’ll butterfly the wound until it can be properly attended to. Again, I’ll need your assistance.”
Nora handed him the requested items, then helped him close. “Did he succeed in finding the ultimate poison?” she asked.
“No. Based on the state of his laboratory, I would say he gave up around 1950.”
“Why?”
“I don’t know,” Pendergast said as he taped gauze over the exit wound. The troubled look she’d noticed earlier returned. “It’s very curious. It’s a great mystery to me.”
Dressing completed, Pendergast straightened up. Following his instructions, Nora helped him make a sling for his injured arm using torn surgical sheets, then helped him into his shirt.
Pendergast turned once again to Smithback, examining his unconscious form, studying the monitors at the head of the table. He felt Smithback’s pulse, examined the dressing Nora had made. After rummaging through the cabinet he brought out a syringe, and injected it into the saline tube.
“That should keep him comfortable until you can get out of here and alert my doctor,” he said.
“Me?” Nora said.
“My dear Dr. Kelly, somebody has to keep watch over Smithback. We daren’t move him ourselves. With my arm in a sling and a gunshot wound in my abdomen, I fear I’m in no condition to go anywhere, let alone row.”
“I don’t understand.”
“You will, shortly. And now, please assist me back down these stairs.”
With a final look at Smithback, Nora helped Pendergast back down the staircase and through the series of stone chambers, past the endless collections. Knowing their purpose made them seem even more dreadful.
At the laboratory, Nora slowed. She angled her light into the weapons room beyond, and saw Fairhaven, still motionless, sitting in the corner. Pendergast regarded him a moment, then moved to the heavy door in the far wall and eased it open. Beyond it lay another descending staircase, much cruder, seemingly fashioned out of a natural cavity in the earth.
“Where does this go?” Nora asked as she approached.
“Unless I’m mistaken, to the river.”
They descended the staircase, the perfume of mold and heavy humidity rising to greet them. At the bottom, Nora’s light revealed a stone quay, lapped by water, with a watery tunnel leading off into darkness. An ancient wooden boat lay upturned on the quay.
“The river pirate’s lair,”Pendergast said as Nora shone the light around. “This was how he snuck out to the Hudson to attack shipping. If the boat’s still seaworthy, you can take it out into the river.”
Nora angled the light toward the skiff.
“Can you row?” Pendergast inquired.
“I’m an expert.”
“Good. I believe you’ll find an abandoned marina a few blocks south of here. Get to a phone as quickly as possible, call 645-7884; that’s the number of my chauffeur, Proctor. Explain to him what’s happened. He’ll come get you and arrange everything, including the doctor for Smithback and myself.”
Nora turned over the rowboat and slid it into the water. It was old, loose-jointed, and leaky, but it appeared to be seaworthy.
