Frock scanned the list, running his finger-down. “Reptilia!” he said. “There are those gecko genes appearing again! It appears that the creature combines reptile and primate genes. And it has posterior scales. They must also be from the gecko genes.”
Margo read down the list of characteristics as they became more and more obscure.
Gross enlargement and fusion of metacarpal bones in rear limb Probable atavistic fusion of forelimb No. 3 & 4 digits Fusion of proximal and middle phalanx on forelimb Extreme thickening of calvaria
Probable 90% (?) negative rotation of ischium Extreme thickening and prismatic cross-sectioning in femur Nasal cavity enlarged
Three (?) highly involute conchae Enlarged olfactory nerves and olfactory region of cerebellum Probable external mucoid nasal glands Reduced optic chiasm, reduced optic nerve
Frock slowly backed himself away from the monitor. “Margo,” he said, “this describes a killing machine of the highest order. But look how many ‘probables’ and ‘possibles’ there are. This is a hypothetical description, at best.”
“Even so,” said Margo, “it sounds an awful lot like the Mbwun figurine in the exhibition.”
“No doubt. Margo, I particularly want to direct your attention to the brain size.”
“Nine to twelve hundred and fifty cubic centimeters,” Margo said, retrieving the printout. “That’s high, isn’t it?”
“High? It’s unbelievable. The upper limit is within human range. This beast, whatever it is, appears to have the strength of a grizzly bear, the speed of a greyhound, and the intelligence of a human being. I say appears; so much of this is conjecture on the part of the program. But look at this cluster of traits.”
He stabbed his finger at the list.
“Nocturnal—active at night. External mucoid nasal glands—that means it has a ‘wet’ nose, possessed by animals with a keen scent. Highly involute conchaealso a trait of animals with enhanced olfactory organs. Reduced optic chiasm—that is the part of the brain that processes eyesight. What we have is a creature with a preternatural sense of smell and very poor eyesight that hunts nocturnally.”
Frock thought for a moment, his brows contracted.
“Margo, this frightens me.”
“If we’re right, the whole idea of this creature frightens me,” Margo replied. She shuddered at the thought that she’d been working with the fibers herself.
“No, I mean this cluster of olfactory traits. If the program’s extrapolation is to be believed, the creature lives by smell, hunts by smell, thinks by smell. I’ve often heard it said that a dog sees an entire landscape of smell, as complex and beautiful as any landscape we see with our eyes. But the olfactory sense is more primitive than sight, and as a result, such animals also have a highly instinctual, primitive reaction to smell. That is what frightens me.”
“I’m not sure I understand.”
“In a few minutes, thousands of people will be arriving in the Museum. They will be congregating together in an enclosed space. The creature will be smelling the concentrated hormonal scent of all these people. That may very well irritate or even anger it.”
A silence settled in the lab.
“Dr. Frock,” Margo said, “you said that a couple of days elapsed from the locking up of the crates and the first killing. Then, another day to the second killing. It’s been three days since then.”
“Go on,” said Frock.
“It just seems to me the creature may be desperate by now. Whatever effect the thalamoid hormones have on the beast must have worn off—after all, those brain hormones are a poor substitute for the plant. If you’re right, the creature must be almost like a drug addict unable to get a fix. All the police activity has kept it lying low. But the question is—how long can it wait?”
“My God,” said Frock. “It’s seven o’clock. We must warn them. Margo, we must stop this opening. Otherwise, we might as well be ringing the dinner bell.” He moved toward the door, motioning her to follow.
