The Alienist - Caleb Carr [235]
We were all agreed on one essential point: that Beecham’s map of the New York City water supply system bore some kind of relevance not to his past killings but to his upcoming one. While waiting for Theodore’s detectives on the night that we’d first discovered Beecham’s flat, Marcus had confirmed his initial theory that the map had been tacked on the wall only recently by making comparative analyses of the wall plaster in different parts of the place. Taking such elements as heat, moisture, and soot into account, Marcus had satisfied himself completely that the map had not been on the wall even as recently as the night of Ernst Lohmann’s murder.
“Splendid!” Theodore judged, giving Marcus a salute. “Precisely why I brought you boys onto the force—modern methods!”
Marcus’s conclusion was further backed up by several other factors. First, it was difficult to see what connection Bedloe’s Island, Bartholdi’s Liberty statue, or indeed any of the other murder sites to date might have had to the city’s water system. In addition, the overall notion of such a system, one of the primary purposes of which was to facilitate bathing, might easily have been metaphorically connected in Beecham’s mind to the figure of John the Baptist. Add to all this the fact that Beecham seemed to have been both taunting and pleading with us by leaving the map behind, and we felt confident in saying that the thing was somehow conceptually tied to the next killing. These details were accordingly entered on the chalkboard by Lucius.
“Bully,” Theodore pronounced as Lucius scribbled. “Bully! This is what I like—a scientific approach!”
None of us had the heart to tell the man that this particular part of our approach was a good deal less scientific than it might have appeared; instead, we took out any and all books we had that related to public works and buildings in Manhattan and embarked on a tour of the island’s water supply system.
Each of Beecham’s 1896 murders had occurred on the banks of a river, from which we had already deduced that the sight of a large body of water had become a vital emotional component of his murderous rituals. It was therefore important to focus our attention on those elements of the water system that were positioned close to the waterfronts. This didn’t leave us with many choices. In fact, it left us, we felt, with only one: the High Bridge Aqueduct and Tower, whose ten-foot pipes had brought clear upstate New York water across the East River and into Manhattan since the 1840s. True, if Beecham had selected High Bridge it would mean his first murder north of Houston Street; yet the simple fact that he had confined his slaughter to Lower Manhattan did not necessarily mean that he was completely unacquainted with the northern end of the island. And it was always possible that Beecham in fact intended to visit some less imposing site on his map—a water main juncture or the like—and was just hoping that we would jump at the more obvious and dramatic High Bridge interpretation.
“But what about the boy’s story?” Theodore asked, deeply frustrated that he could not be more involved in the speculative process. “The ‘castle that
