“You know this woman, my boy, don’t you?”

“No,” said William, “I’ve never seen her before.”

The doctor looked pleased. “Doesn’t remember his own mother,” he said to his wife: “quite an interesting case.”

The woman approached them aggressively. The doctor stepped in front of William.

“Come after my boy,” she said, “Sayin’ ’is hours ended at five an’ then keepin’ ’im till now! I’ll ’ave the lor on you, I will. Where is ’e?”

“Prepare yourself, my good woman,” said the doctor, “for a slight shock. Your son has temporarily—only temporarily, we trust—lost his memory.”

She screamed.

“HERE IS YOUR SON,” SAID THE DOCTOR POMPOUSLY.
