only to pass his fingers lightly over the brass knob of the door。 His business lay elsewhere； below； with things older and infinitely stranger。
He had mentioned to Nora his inability to maintain proper intellectual distance in the case； and this was undeniably true。 This was what had led him； and her…and； to his deepest sorrow； Patrick O'Shaughnessy…into the present misfortune。 What he had not revealed to Nora was the profound shock he felt when he saw the face of the dead man。 It was； as he now knew； Enoch Leng…or； more accurately； his own great…grand…uncle； Antoine Leng Pendergast。
For Great…Grand…Uncle Antoine had succeeded in his youthful dream of extending his life。
The last remnants of the ancient Pendergast family…those who were pos mentis…assumed that Antoine had died many years ago； probably in New York； where he had vanished in the mid ninteenth century。 A significant portion of the Pendergast family fortune had vanished with him； much to the chagrin of his collateral descendants。
But several years before； while working on the case of the Subway Massacre； Pendergast…thanks to Wren； his library acquaintance…had stumbled by chance upon some old newspaper articles。 These articles described a sudden rash of disappearances： disappearances that followed not long after the date Antoine was supposed to have arrived in New York。 A corpse had been discovered； floating in the East River； with the marks of a diabolical kind of surgery。 It was a street waif； and the crime was never solved。 But certain unfortable details caused Pendergast to believe it to be the work of Antoine； and to feel the man was attempting to achieve his youthful dream of immortality。 A perusal of later newspapers brought a half…dozen similar crimes to light； stretching as far forward as 1935。
The question； Pendergast realized； became： had Leng succeeded？ Or had he died in 1935？
Death seemed by far the most likely result。 And yet； Pendergast had remained uneasy。 Antoine Leng Pendergast was a man of transcendental genius； bined with transcendental madness。
So Pendergast waited and watched。 As the last of his line； he'd felt it his responsibility to keep vigil against the unlikely chance that； someday； evidence of his ancestor's continued existence would resurface。 When he heard of the discovery on Catherine Street； he immediately suspected what had happened there； and who was responsible。 And when the murder of Doreen Hollander was discovered； he knew that what he most dreaded had e to pass： Antoine Pendergast had succeeded in his quest。
But now； Antoine was dead。
There could be no doubt that the mummified corpse in the glass case was that of Antoine Pendergast； who had taken； in his journey northward； the name Enoch Leng。 Pendergast had e to the house on Riverside Drive expecting to confront his own ancestor。 Instead； he had found his great…grand…uncle tortured and murdered。 Someone； somehow； had taken his place。
Who had killed the man who called himself Enoch Leng？ Who now held them prisoner？ The corpse of his ancestor was only recently dead…the state of the corpse suggested that death had occurred within the last two months…pegging the murder of Enoch Leng before the discovery of the charnel on Catherine Street。
The timing was very； very interesting。
And then there was that other problem…a very quiet； but persistent feeling that there was a connection still to be made here…that had been troubling Pendergast almost since he first set foot within Leng's house。
Now； inside the memory crossing； he continued down the hall。 The next door…the door that had once been his brother's…had been sealed by Pendergast himself； never to be opened again。 He quickly moved on。
The hallway ended in a grand； sweeping staircase leading down to a great hall。 A heavy cut…glass chandelier hovered over the marble floor； mounting on a gilt chain to a domed trompe l'oeil ceiling。 Pendergast descended the stairs； deep in thought。 To one side； a set of tall doors opened into a two…story library； to the other； a long hall retreated back into shadow。 Pendergast entered this hall first。 Originally； this room had been the monastery's refectory。 In his mind； he had furnished it with a variety of family heirlooms： heavy rosewood chiffoniers； oversized landscapes by Bierstadt and Cole。 There were other； more unusual heirlooms here； as well： sets of Tarot cards； crystal balls； a spirit…medium apparatus； chains and cuffs； stage props for illusionists and magicians。 Other objects lay in the corners； shrouded； their outlines sunken too deeply into shadow to discern。
As he looked around； his mind once again felt the ripples of a disturbance； of a connection not yet made。 It was here； it was all around him； it only awaited his recognition。 And yet it hovered tantalizingly out of grasp。
This room could tell him no more。 Exiting； he re…crossed the echoing hall and entered the library。 He looked around a moment； savoring the books； real and imaginary； row upon forting row； that rose to the molded ceiling far above。 Then he stepped toward one of the shelves on the nearest wall。 He glanced along the rows； found the book he wanted； pulled it from the shelf。 With a low； almost noiseless click； the shelf swung away from the wall。
。 。 。 And then； abruptly； Pendergast found himself back in Leng's house on Riverside Drive； standing in the grand foyer； surrounded by Leng's astonishing collections。
He hesitated； momentarily stilled by surprise。 Such a shift； such a morphing of location； had never happened in a memory crossing before。
But as he waited； looking around at the shrouded skeletons and shelves covered with treasures； the reason became clear。 When he and Nora first passed through the rooms of Leng's house…the grand foyer； the long； low…ceilinged exhibit hall； the two…storied library…Pendergast had found himself experiencing an unexpected； unfortable feeling of familiarity。 Now he knew why： in his house on Riverside Drive； Leng had re…created； in his own dark and twisted way； the old Pendergast mansion on Dauphine Street。
He had finally made the crucial connection。 Or had he？
Great…Uncle Antoine？ Aunt Cornelia had said。 He went north； to New York City。 Became a Yankee。 And so he had。 But； like all members of the Pendergast family； he had been unable to escape his legacy。 And here in New York； he had re…created his own Maison de la Rochenoire…an idealized mansion； where he could amass his collections and carry on his experiments； undisturbed by prying relations。 It was not unlike； Pendergast realized； the way he himself had re…created the Maison de la Rochenoire in his own mind； as a memory palace。
This much； at least； was now clear。 But his mind remained troubled。 Something else was eluding him： a realization hovering at the very edge of awareness。 Leng had a lifetime； several lifetimes； in which to plete his own cabinet of curiosities。 Here it was； all around him； possibly the finest natural history collection ever assembled。 And yet； as Pendergast looked around； he realized that the collection was inplete。 One section was missing。 Not just any section； in fact； but the central collection： the one thing that had fascinated the young Antoine Leng Pendergast most。 Pendergast felt a growing astonishment。 Antoine…as Leng…had had a century and a half to plete this ultimate cabinet of curiosities。 Why was it not here？
Pendergast knew it existed。 It must exist。 Here； in this house。 It was just a question of where 。 。 。
A sound from the outside world…a strangely muffled scream…suddenly intruded into Pendergast's memory crossing。 Quickly； he withdrew again； plunging as deeply as he could into the protective darkness and fog of his own mental construct； trying to recover the necessary purity of concentration。
Time passed。 And then； in his mind； he found himself once again back in the old house on Dauphine Street； standing in the library。
He waited a moment； re…acclimating himself to the surroundings； giving his new suspicions and questions time to mature。 In his mind's eye he recorded them on parchment and bound them between gilt covers； placing the book on one of the shelves beside a long row of similar books…all books of questions。 Then he
