“Only a month or so, but she is crazy about him.”

“And when he came last night she went away with him?”

“Yes. She was all ready to go before the other gentleman called. He must have told her something which made her think it was all off, and she was crazy with joy when Sidney turned up. She had all her things packed, and off she went.”

Experience had taught Detective Inspector Wessex to recognize the truth when he met it, and he did not doubt the statement of the woman with the baby. “Can you give me any idea where this man Sidney came from?” he asked.

“I am afraid I can’t,” replied the listless voice. “He was in the service of some gentleman in the country; that’s all I know about him.”

“Did Polly leave no address to which letters were to be forwarded?”

“No; she said she would write.”

“One other point,” said Wessex, and he looked hard into the woman’s face: “What do you know about Fire-Tongue?”

He was answered by a stare of blank stupidity.

“You heard me?”
