School was just commencing that morning when Peter Corner left it. He owed his freedom to his ability to take unscrupulous advantage of the caprice of circumstance, and the credulity of his fellows. His two sisters had colds, and his mother had kept them at home. Had he reported to his schoolmistress that his mother suspected measles he would have incurred the risk of ultimate retribution, which he was always adroit to avoid. Instead of that, he made the remark to Jessie Phipson, who could be relied upon to report it promptly. Challenged on the point, he strenuously denied the truth of the suggestion. His mother had never said so. He had told Jessie that they had not got measles
His expression was almost good-tempered as he dragged his clubfoot toward Dr. Merson’s surgery. His sisters usually called for his mother’s medicine, but as they had not come to school to-day the duty fell to him. He did not like going there. He hated Dr. Merson. He hated his eyes, which seemed to see through him without effort, and then to look elsewhere, as though he were not worth seeing. But he had to go today, and he had a hopeful idea this morning. He did not expect to get the medicine before noon. He knew that the doctor was not at home during the mornings. But he could not be blamed for calling on his way home.
He found the surgery door unlocked, as it was sometimes left when Dr. Merson was absent. He had expected that. He knew when and whether most of the doors in Belsham were locked or open. He did not often make use of this knowledge. His physical deformity, and the practical difficulties of secreting or disposing of illicit gains, had withheld him from active dishonesties. But in his waking dreams (for he had them, as much as more attractive children) he was most often a cat burglar of superhuman audacities.
Had he rung the surgery bell, the maid would have come, or the doctor’s wife, but he turned the handle without haste or hesitation, and stood quietly inside, in an attitude of respectful waiting, till he was reassured by the surrounding silence. Then he passed through to the passage. He could not move very quietly, but a sound of crockery in the distant kitchen reassured him, and — beyond his hopes — the key was in the door on the other side of the passage.
Dr. Merson did not often experiment with living animals, but it was generally known that he held a vivisection certificate. It was the dream of Peter’s life to enter that room, and view the horrors which he vaguely imagined to be concealed behind the frosted glass that could be seen sideways from the road, if you forced your face sufficiently far between the palings.
Now the door was not even locked, though the key was in it. Peter opened it quietly, entered, and closed it behind him.

Dr. Merson had not gone far when he was vexed by a doubt as to whether he had locked the door. He was almost sure that he had — yes, he was quite sure — but he felt vaguely uneasy. He felt for the key in its usual pocket, but it was not there. He felt in his other pockets, with the same result. He must have left it in the door. He felt sure now that he had turned the key, but not removed it. That was what had made his mind uneasy. Really, it didn’t matter. No one of his household would enter the room under such circumstances. Certainly Molly wouldn’t. She hated the room, and never entered it except to seek him. More certainly still, the maid would not venture. She would not enter to dust it. Not that he wanted her to. Women are a curse where a man works. But he knew her feeling. It was, in fact, her talk in the village which was mainly responsible for the fact that Peter Corner was now inside it. But Dr. Merson didn’t know that. He only thought that if the women of his household found the door locked and the key outside they would know that he couldn’t be in, and would be unlikely to enter. But was he sure he had locked it?
Probably he wouldn’t have turned back, being so late already, had he not discovered, to his added annoyance, that he had left behind some clinical notes which he should require at the consultation for which he was late already.
He went back hastily. On the way, he made a resolution that he would kill the rat that night, and destroy the serum he had invented. He perceived, with a sudden clarity, that the world’s Creator might understand His job better than a local practitioner in Belsham village.
The relief that the decision gave him confirmed its wisdom. He was in better spirits than he had been for many weeks as he passed through the surgery, and crossed the passage to the room beyond.
