"Is that all you saw?"
She was sulky again. After a time she muttered. She wrinkled her face but the tears would not come. Presently she said, and the detective caught an effort on her part to say it.
"Yes. But I think I heard a door slam downstairs."
"You think you heard a door slam? What happened next?"
"How long after the door slammed was it before your husband came?"
"Not long."
"Is it not possible that when you heard the door slam, that it was your husband coming in?"
"No. I heard the door slam behind him, too." Again he thought he detected something singular in her manner, as if she were not telling all she knew....
The detective went downstairs and talked with Mrs. McCarthy a few minutes, and then took his leave. He called up Agnes, and made an appointment and met her some hours later.
