His wife gazed from the defiant pose to the locked door visible through the parlour. She stirred angrily in her clothes and speared a morsel of food. “You’ll be punished for it.”
Later in the day Mudge and Gropper laughed heartily at the expense of the former’s erstwhile host. Danner read restively. He was forbidden to work on the Sabbath. It was his only compromise. Matilda Danner turned the leaves of the Bible and meditated in a partial vacuum of daydreams.
On Monday Danner hastened home from his classes. During the night he had had a new idea. And a new idea was a rare thing after fourteen years of groping investigation. “Alkaline radicals,” he murmured as he crossed his lawn. He considered a group of ultramicroscopic bodies. He had no name for them. They were the “determinants” of which he had talked. He locked the laboratory door behind himself and bent over the microscope he had designed. “Huh!” he said. An hour later, while he stirred a solution in a beaker, he said: “Huh!” again. He repeated it when his wife called him to dinner. The room was a maze of test tubes, bottles, burners, retorts, instruments. During the meal he did not speak. Afterwards he resumed work. At twelve he prepared six tadpole eggs and put them to hatch. It would be his three hundred and sixty-first separate tadpole hatching.
Then, one day in June, Danner crossed the campus with unusual haste. Birds were singing, a gentle wind eddied over the town from the slopes of the Rocky Mountains, flowers bloomed. The professor did not heed the reburgeoning of nature. A strange thing had happened to him that morning. He had peeped into his workroom before leaving for the college and had come suddenly upon a phenomenon.
One of the tadpoles had hatched in its aquarium. He observed it eagerly, first because it embodied his new idea, and second because it swam with a rare activity. As he looked, the tadpole rushed at the side of its domicile. There was a tinkle and a splash. It had swum through the plate glass! For an instant it lay on the floor. Then, with a flick of its tail, it flew into the air and hit the ceiling of the room.
“Good Lord!” Danner said. Old years of work were at an end. New years of excitement lay ahead. He snatched the creature and it wriggled from his grasp. He caught it again. His fist was not sufficiently strong to hold it. He left it, flopping in eight-foot leaps, and went to class with considerable suppressed agitation and some reluctance. The determinant was known. He had made a living creature abnormally strong.
When he reached his house and unlocked the door of the laboratory, he found that four tadpoles, in all, had hatched. Before they expired in the unfamiliar element of air, they had demolished a quantity of apparatus.
Mrs. Danner knocked on the door. “What’s been going on in there?”
“Nothing,” her husband answered.
“Nothing! It sounded like nothing! What have you got there? A cat?”
“No—yes.”
“Well—I won’t have such goings on, and that’s all there is to it.”
Danner collected the debris. He buried the tadpoles. One was dissected first. Then he wrote for a long time in his notebook. After that he went out and, with some difficulty, secured a pregnant cat. A week later he chloroformed the tabby and inoculated her. Then he waited. He had been patient for a long time. It was difficult to be patient now.
When the kittens were born into this dark and dreary world, Mr. Danner assisted as sole obstetrician. In their first hours nothing marked them as unique. The professor selected one and drowned the remainder. He remembered the tadpoles and made a simple calculation.
When the kitten was two weeks old and its eyes opened, it was dieting on all its mother’s milk and more besides. The professor considered that fact significant. Then one day it committed matricide.
Probably the playful blow of its front paw was intended in the best spirit. Certainly the old tabby, receiving it, was not prepared for such violence from its offspring. Danner gasped. The kitten had unseamed its mother in a swift and horrid manner. He put the cat out of its misery and tended the kitten with trepidation. It grew. It ate—beefsteaks and chops, bone and all.
When it reached three weeks, it began to jump alarmingly. The laboratory was not large enough. The professor brought it its food with the expression of a man offering a wax sausage to a hungry panther.
On a peaceful Friday evening Danner built a fire to stave off the rigours of a cold snap. He and Mrs. Danner sat beside the friendly blaze. Her sewing was in her lap, and in his was a book to which he paid scant attention. The kitten, behind its locked door, thumped and mewed.
“It’s hungry,” Mrs. Danner said. “If you must keep a cat, why don’t you feed it?”
“I do,” he answered. He refrained, for politic reasons, from mentioning what and how much he fed it. The kitten mewed again.
“Well,” she repeated, “it sounds hungry.”
Danner fidgeted. The laboratory was unheated and consequently chilly. From its gloomy interior the kitten peered beneath the door and saw the fire. It sensed warmth. The feline affinity for hearths drew it. One paw scratched tentatively on the door.
“It’s cold,” Mrs. Danner said. “Why don’t you bring it here? No, I don’t want it here. Take it a cover.”
“It—it has a cover.” Danner did not wish to go into that dark room.
The kitten scratched again and then it became earnest. There was a splitting, rending sound. The bottom panel of the door was torn away and it emerged nonchalantly, crossing the room and curling up by the fire.
For five minutes Mrs. Danner sat motionless. Her eyes at length moved from the kitten to her husband’s quivering face and then to the broken door. On his part, he made no move. The kitten was
