“You’re right, of course,” Frock said, wheeling [450] himself back toward his desk. “We know the creature was highly intelligent. It realized it would be in danger if its existence in the Museum was discovered. I think it must have curbed its normally fierce nature as a means of self-preservation. When it first reached the Museum, it was desperate, perhaps feral, and it killed Montague when it saw him with the artifacts and the plants. But after that, it grew quickly cautious. It knew where the crates were, and it had a supply of the plant—or, at least, it would until the packing material gave out. It was parsimonious in its consumption. Of course, the hormones in the plant were highly concentrated. And the beast supplemented its diet occasionally, in stealthy ways. Rats living in the subbasement, cats escaped from the Animal Behavior department ... once or twice, even luckless human beings that wandered too deep into the Museum’s secret places. But it was always careful to conceal its kills, and several years passed in which it remained—for the most part—undetected.” He shifted slightly, the wheelchair creaking.
“Then it happened. The crates were removed, put under lock and key in the Secure Area. The beast grew first hungry, then desperate. Perhaps it grew murderous with rage at the beings who had deprived it of the plants—beings who themselves could be a substitute, though poor, for that which they’d taken away. The frenzy grew, and the beast killed, then killed again.”
Frock withdrew his handkerchief and wiped his forehead. “But it didn’t lose all rationality,” he continued. “Remember how it hid the body of the policeman in the exhibition? Even though its blood lust had been aroused, even though it was mad with desire for the plants, it had the presence of mind to realize that the killings were attracting unwanted attention to itself. Perhaps it had planned on bringing the body of Beauregard back down to its lair. Chances are, it was unable to do so—the exhibition was far beyond its usual haunts—so it hid the [451] body instead. After all, the hypothalamus was its primary objective; the rest was just meat.”
Margo shuddered.
“I’ve wondered more than once just why the beast went into that exhibition,” Pendergast said.
Frock raised his index finger. “So have I. And I think I know the reason. Remember, Mr. Pendergast, what else was in the exhibition.”
Pendergast nodded slowly. “Of course. The figurine of Mbwun.”
“Exactly,” said Frock. “The figurine depicting the beast itself. The creature’s one link with its home, the home that it had lost utterly.”
“You seem to have it all figured out,” Smithback said. “But if Wright and Cuthbert were aware of this thing, how did they know it was connected with the Whittlesey expedition?”
“I believe I can answer that,” Pendergast said. “They knew, of course, why the ship carrying the crates from Belém to New Orleans was delayed so long—much the way you learned, I expect, Mr. Smithback.”
Smithback suddenly looked nervous. “Well,” he began, “I—”
“They also read Whittlesey’s journal. And they knew the legends as well as anybody. Then, when Montague—the person assigned to curating the crates—disappeared, and a pool of blood was discovered near the location of the crates, it didn’t take a savant to put everything together. And besides,” he said, his expression clouding, “Cuthbert more or less confirmed it for me. As well as he was able, of course.”
Frock nodded. “They paid a terrible price. Winston and Lavinia dead, Ian Cuthbert institutionalized ... it’s distressing beyond words.”
“True,” Kawakita said, “but it’s no secret that it’s made you top contender for the next Director of the Museum.”
He would think of that, Margo thought.
[452] Frock shook his head. “I doubt if it will be offered me, Gregory. Once the dust settles, rational heads will prevail. I’m too controversial. Besides, the Directorship doesn’t interest me. I have too much new material here for me to delay my next book any longer.”
“One thing that Dr. Wright and the rest didn’t know,” Pendergast went on—“in fact, something that nobody here knows—is that the killings didn’t start in New Orleans. There was a very similar murder in Belém, in the warehouse where the crates had been housed while awaiting shipping. I learned about it when I was investigating the shipboard killings.”
“That must have been the creature’s first stop on the way to New York,” Smithback said. “I guess it brings the story full circle.” He guided Pendergast to the sofa. “Now, Mr. Pendergast, I suppose this also solves the mystery of what happened to Whittlesey.”
“The creature killed him, that seems fairly certain,” said Pendergast. “Say, you don’t mind if I get a piece of that cake—”
Smithback placed a restraining hand on his arm. “How do you know?”
“That it killed Whittlesey? We found a souvenir in its lair.”
“You did?” Smithback whipped out his microcassette recorder.
“Put that back in your pocket, if you please, Mr. Smithback. Yes, it was something Whittlesey wore around his neck, apparently. A medallion in the shape of a double arrow.”
“That was embossed on his journal!” Smithback said. “And on the letterhead of the note he sent Montague!” Margo chimed in.
“Apparently it was Whittlesey’s family crest. We found it in the lair; a piece of it, anyway. Why the beast carried it from the Amazon we’ll never know, but there it is.”
“We found other artifacts in there, too,” said [453] D’Agosta, through a mouthful of cake. “Along with a pile of Maxwell’s seed pods. The thing was a regular collector.
“Like what?” Margo asked, walking toward one of the bow windows and gazing out at the landscape beyond.
“Things you wouldn’t expect. A set of car keys, a lot of coins and subway tokens, even a beautiful gold pocket watch. We looked up the guy whose name was inscribed inside the watch, and he told us he’d lost it three years ago. He’d visited the Museum, and been pickpocketed.” D’Agosta shrugged. “Maybe that pickpocket is one of the unidentified bodies. Or maybe we’ll never find him.”
“The creature kept it hung by its chain from a nail in the wall of its lair,” Pendergast said. “It liked beautiful things. Another sign of intelligence, I suppose.”
“Was everything picked up from inside the Museum?” asked Smithback.
“As far as we can tell,” Pendergast said. “There’s no evidence the creature could—or wanted to—obtain egress from the Museum.”
“No?” Smithback said. “Then what about the exit you were leading D’Agosta toward?”
“He found it,” Pendergast said simply. “You were all very lucky.”
Smithback turned to ask D’Agosta another question, and Pendergast took the opportunity to get up and head for the cake. “It was awfully nice of you to throw me this party, Dr. Frock,” he said as he returned.
“You saved our lives,” Frock said. “I thought a little cake might be in order as our way of wishing you bon voyage.”
“I’m afraid, then,” Pendergast continued, “that I may be at this party under false pretenses.”
“Why is that?” Frock asked.
“I may not be leaving New York permanently. The directorship of the New York office is up for reassignment, you see.”
[454] “You mean it’s not going to Coffey?” Smithback smirked.
Pendergast shook his head. “Poor Mr. Coffey,” he said. “I hope he enjoys his position in the Waco field office. In any case, the Mayor, who has become a great fan of Captain D’Agosta here, seems to think I have a good shot at it.”
