"Uncle!"
The quiet voice of the girl Carmen cut softly across the muted shriek in which the last words were spoken, so quietly and normally that it was only in the contrast that Simon realized that Sardon had not really raised his voice.
The wild fire died slowly out of Sardon's eyes. For a moment his face remained set and frozen, and then, as if he had only been recalled from a fleeting lapse of attention, he seemed to come awake again with a slight start.
"Where was I?" he said calmly. "Oh yes. I was speaking about the intelligence of ants. ... It is even a mistake to assume, because they make no audible sounds, that they have not just as excellent means of communication as ourselves. Whether they share the telepathic gifts of other insects is a disputed point, but it is certain that in their antennae they possess an idiom which is adequate to all ordinary needs. By close study and observation it has even been possible for us to learn some of the elementary gestures. The work of Karl Escherich . . ."
He went into details, in the same detached incisive tone in which he had been speaking before his outburst.
Simon Templar's fingers stroked over the cloth, found a crumb of bread and massaged it gradually into a soft round pellet. He stole a casual glance at the girl. Her aloof oval face was pale, but that might have been its natural complexion; her composure was unaltered. Sardon's outburst might never have occurred, and she might never have had to interrupt it. Only the Saint thought that he saw a shadow of fear moving far down in her eyes.
Even after Carmen had left the table, and the room was richening with the comfortable aromas of coffee and liqueur, brandy and cigars, Sardon was still riding his hobbyhorse. It went on for nearly an hour, until at one of the rare lulls in the discussion Nordsten said: "All the same, Doctor, you are very mysterious about what this has to do with your own experiments."
Sardon's hands rested on the table, white and motion less, the fingers spread out.
"Because I was not ready. Even to my friends I should not like to show anything incomplete. But in the last few weeks I have disposed of my uncertainty. Tonight, if you like, I could show you a little"
"We should be honoured."
The flat pressure of Sardon's hands on the table increased as he pushed back his chair and stood up.
"My workshops are at the end of the garden," he said, and blew out the four candles.
As they rose and followed him from the room, Nordsten touched the Saint's arm and said in a low voice : "Are you sorry I dragged you out?"
"I don't know yet," answered the Saint soberly.
The girl Carmen rejoined them as they left the house. Simon found her walking beside him as they strolled through the warm moonlight. He dropped the remains of his cigar and offered his cigarette case; they stopped for a moment while he gave her a light. Neither of them spoke, but her arm slipped through his as they went on.
The blaze of lights which Sardon switched on in his laboratory wiped the dim silvery gloom out of their eyes in a crash of harsh glaring illumination. In contrast with the tasteful furnishings of the house, the cold white walls and bare tiled floor struck the Saint's sensitive vision with the hygienic and inhuman chill which such places always gave him. But Sardon's laboratory was not like any other place of that kind in which he had ever been.
Ranged along the walls were rows of big glass-fronted boxes, in which apparently formless heaps of litter and rubble could be dimly made out. His tye was caught by a movement in one of the boxes, and he stepped up to look at it more closely. Almost in the same moment he stopped, and nearly recoiled from it, as he realized that he was looking at the largest ant that he had ever seen. It was fully six inches long; and, magnified in that proportion, he could see every joint in its shiny armour-plated surface and the curious bifurcated claws at the ends of its legs. It stood there with its antennae waving gently, watching him with its bulging beady eyes . . .
"Tetramorium cespitum," said Dr Sardon, standing beside him. "One of my early experiments. Its natural size is about three tenths of an inch, but it did not respond very well to treatment."
"I should say it had responded heroically," said the Saint. "You don't mean you can do better than that?"
Sardon smiled.
"It was one of my early experiments," he repeated. "I was then merely trying to improve on the work of Ludwig and Ries of Berne, who were breeding giant insects almost comparable with that one, many years ago, with the aid of red light. Subsequently I discovered another principle of growth which they had overlooked, and I also found that an artificial selective cross-breeding between different species not only improved the potential size but also increased the intelligence. For instance, here is one of my later results--a combination of Oecophylla smaragdina and Prenolepsis imparis."
He went to one of the longer and larger boxes at the end of the room. At first Simon could see nothing but a great mound of twigs and leaves piled high in one corner. There were two or three bones, stripped bare and white, lying on the sandy floor of the box. . . . Then Sardon tapped on the glass, and Simon saw with a sudden thrill of horror that what had been a dark hole in the mound of leaves was no longer black and empty. There was a head peering out of the shadow-- dark bronze-green, iridescent, covered with short sparse bristly hairs. . . .
"Oecophylla is, of course, one of the more advanced species," Sardon was saying, in his calm precise manner. "It is the only known creature other than man to use a tool. The larvae secrete a substance similar to silk, with which the ants weave leaves together to make their nests, holding the larvae in their jaws and using them as shuttles. I don't yet know whether my hybrid has inherited that instinct."
"It looks as if it would make a charming pet, anyway," murmured the Saint thoughtfully. "Sort of improved lap dog, isn't it?"
The faint sly smile stayed fixed on Sardon's thin lips. He took two steps further, to a wide sliding door that took up most of the wall at the end of the laboratory, and looked back at them sidelong.
"Perhaps you would like to see the future ruler of the world," he said, so very softly that it seemed as if everyone else stopped breathing while he spoke.
Simon heard the girl beside him catch her breath, and Nordsten said quickly: "Surely we've troubled you enough already----"
'I should like to see it," said the Saint quietly.
Sardon's tongue slid once over his lips. He put his hand up and moved a couple of levers on the glittering panels of dials and switches beside the door. It was to the Saint that his gaze returned, with that rapt express sion of strangely cunning and yet childish happiness.
"You will see it from where you stand. I will ask you to keep perfectly still, so as not to draw attention to yourselves--there is a strain of Dorylina in this one. Dorylina is one of the most intelligent and highly disciplined species, but it is also the most savage. I do not wish it to become angry----"
His arm stretched out to the handle of the door. He slid it aside in one movement, standing with his back ||
to it, facing them.
The girl's cold hand touched the Saint's wrist. Her fingers slipped down over his hand and locked in with his own, clutching them in a sudden convulsive grip. He heard Ivar Nordsten's suppressed gasp as it caught in his throat, and an icy tingle ran up his spine and broke out in a clammy dew on his forehead.
The rich red light from the chamber beyond the door spilled out like liquid fire, so fierce and vivid that it seemed as if it could only be accompanied by the scorching heat of an open furnace; but it held only a slight appreciable warmth. It beat down from huge crimson arcs ranged along the cornices of the inner room among a maze of shining tubes and twisted wires; there was a great glass ball opposite in which a pale- yellow streak of lightning forked and flickered with a faint humming sound. The light struck scarlet highlights from the-gleaming bars of a great metal cage like a gigantic chicken coop which filled the centre of the room to within a yard of the walls. And within the cage something monstrous and incredible stood motionless, staring at them.
