"I've told you everything, sir," she said quietly.

"You've not told me you found the meter turned on when you got up next morning," replied the detective sternly.

The woman's fat face turned haggard with anxiety, and then she began to cry softly with her apron to her eyes.

"Why did you not tell us this, Ann?"

"If you please, sir, I thought that the master mightn't like it if he knew. He's very particular about having the gas turned off at night, and he might have thought I had forgotten it."

Colwyn gave her another searching look.

"Even if that were true, Ann, you have no right to keep back anything that may tend to shield the guilty, or injure the innocent."

"I didn't think it mattered, sir."

"You still say that you heard nothing after you went to bed?"

"No, sir. I fell asleep as soon as I got into bed."
