He felt the bullet strike his right elbow； a sledgehammer blow that knocked him off his feet。 He lay on the ground for a moment； as the laser licked through the dusty air。 Then he rolled to his feet and limped forward； ducking from case to case as he crossed the room。
He had allowed himself to bee distracted by the strange collection； he had neglected to listen for Fairhaven's approach。 Once again； he had failed。 With this thought came the realization that； for the first time； he was about to lose。
He took another step forward； cradling his shattered elbow。 The bullet seemed to have passed above the medial supracondlar ridge and exited near the coronoid process of the ulna。 It would aggravate the blood loss； render him incapable of resistance。 He must get to the next room。 Each room had its own clues； and perhaps the next would reveal Leng's secret。 But as he moved a wave of dizziness hit him； followed by a stab of nausea。 He swayed； steadied himself。
Using the reflected light of Fairhaven's searching beam； he ducked beneath an archway into the next room。 The exertion of the fall； the shock of the second bullet； had drained the last of his energy； and the heavy curtain of unconsciousness drew ever closer。 He leaned back against the inside wall； breathing hard； eyes wide against the darkness。
The flashlight beam stabbed abruptly through the archway； then flicked away again。 In its brief illumination； Pendergast saw the glitter of glass； rows of beakers and retorts； columnar distillation setups rising like city spires above long worktables。
He had penetrated Enoch Leng's secret lab。

NORA STOOD OVER the metal table； her gaze moving from the monitoring machines to Smithback's pallid form； then back again。 She had removed the retractors； cleaned and dressed the wound as best she could。 The bleeding had finally stopped。 But the damage was already done。 The blood pressure machine continued to sound its dire warning。 She glanced toward the saline bag： it was almost empty； but the catheter was small； and even at maximum volume it would be difficult to replenish lost fluids quickly enough。
She turned abruptly as the sound of a second shot echoed up from the dark staircase。 It sounded faint； muffled； as if ing from deep underground。
For a moment she stood motionless； lanced by fear。 What had happened？ Had Pendergast shot…or been shot？
Then she turned back toward Smithback's inert form。 Only one man was going to e up that staircase： Pendergast； or the other。 When the time came； she'd deal with it。 Right now； her responsibility lay with Smithback。 And she wasn't going to leave him。
She glanced back at the vitals： blood pressure down to 70 over 35； the heart rate slowing too； now； down to 80 beats per minute。 At first； this latter development sent relief coursing through her。 But then another thought struck； and she raised her palm to Smithback's forehead。 It was growing as cold as his limbs had been。
Bradycardia； she thought； as panic replaced the transitory feeling of relief。 When blood loss is persistent； and there are no more areas for the body to shut down； the patient depensates。 The critical areas start to go。 The heart slows。 And then stops for good。
Hand still on Smithback's forehead； Nora turned her frantic gaze back to the EKG。 It looked strangely diminished； the spikes smaller； the frequency slower。 The pulse was now 50 beats per minute。
She dropped her hands to Smithback's shoulders； shook him roughly。 〃Bill！〃 she cried。 〃Bill； damn it； e on！ Please！〃
The peeping of the EKG grew erratic。 Slowed。
There was nothing more she could do。
She stared at the monitors for a moment； a horrible feeling of powerlessness stealing over her。 And then she closed her eyes and let her head sink onto Smithback's shoulder： bare； motionless； cold as a marble tomb。

PENDERGAST STUMBLED PAST the long tables of the old laboratory。 Another spasm of pain wracked his gut and he paused momentarily； mentally willing it to pass。 Despite the severity of his wounds； he had so far managed to keep one corner of his mind clear； sharp； free of distraction。 He tried to focus on that corner through the thickening fog of pain； tried to observe and understand what lay around him。
Titration and distillation apparatuses； beakers and retorts； burners； a vast thicket of glassware and metal。 And yet； despite the extent of the equipment； there seemed to be few clues to the project Leng had been working on。 Chemistry was chemistry； and you used the same tools and equipment； regardless of what chemicals you were synthesizing or isolating。 There were a larger number of hoods and vintage glove boxes than Pendergast expected； implying that Leng had been handling poisons or radioactive substances in his laboratory。 But even this merely corroborated what he had already surmised。
The only surprise had been the state of the laboratory。 There was no mass spectrometer； no X…ray diffraction equipment； no electrophoresis apparatus； and certainly no DNA sequencer。 No puters； nothing that seemed to contain any integrated circuits。 There was nothing to reflect the revolution in biochemistry technology that had occurred since the 1960s。 Judging by the age of the equipment and its neglected condition； it looked； in fact； as if all work in the lab had ceased around fifty years before。
But that made no sense。 Leng would certainly have availed himself of the latest scientific developments； the most modern equipment； to help him in his quest。 And； until very recently； the man had been alive。
Could Leng have finished his project？ If so； where was it？ What was it？ Was it somewhere in this vast basement？ Or had he given up？
The flicker of Fairhaven's light was licking closer now； and Pendergast ceased speculating and forced himself onward。 There was a door in the far wall； and he dragged himself toward it through an overwhelming wash of pain。 If this was Leng's laboratory； there would be no more than one； perhaps two； final workrooms beyond。 He felt an almost overpowering wave of dizziness。 He had reached the point where he could barely walk。 The endgame had arrived。
And still he didn't know。
Pendergast pushed the door ajar； took five steps into the next room。 He uncloaked the lantern and tried to raise it to get his bearings； examine the room's contents； make one final attempt at resolving the mystery。
And then his legs buckled beneath him。
As he fell； the lantern crashed to the floor； rolling away； its light flickering crazily across the walls。 And along the walls； a hundred edges of sharpened steel reflected the light back toward him。

THE SURGEON SHONE the light hungrily around the chamber as the echoes of the second shot died away。 The beam illuminated moth…eaten clothing； ancient wooden display cases； motes of disturbed dust hanging in the air。 He was certain he had hit Pendergast again。
The first shot； the gut shot； had been the more severe。 It would be painful； debilitating； a wound that would grow steadily worse。 The last kind of wound you wanted when you were trying to escape。 The second shot had hit a limb…an arm； no doubt； given that the FBI agent could still walk。 Exceedingly painful； and with luck it might have nicked the basilic vein； adding to Pendergast's loss of blood。
He stopped where Pendergast had fallen。 There was a small spray of blood against a nearby cabinet； and a heavier smear where the agent had obviously rolled across the ground。 He stepped back； glancing around with a feeling of contempt。 It was another of Leng's absurd collections。 The man had been a neurotic collector； and the basement was of a piece with the rest of the house。 There would be no arcanum here； no philosopher's stone。 Pendergast had obviously been trying to throw him off balance with that talk of Leng's ultimate purpose。 What purpose could be more grand than the prolongation of the human life span？ And if this ridiculous collection of umbrellas and walking sticks and wigs was an example of Leng's ultimate project； then it merely corroborated how unfit he was for his own discovery。 Perhaps with the long； cloistered years had e madness。 Although Leng had seemed quite sane when
