“Nothing. What should I do? As a matter of fact I didn’t think they were shots. I thought them tire explosions or some noise in the street. But after I knew about the murder, I realized that I had heard the fatal shot.”

“Yet you said nothing to anybody?”

“Man alive, what could I say? I had nothing to do with Mr Gleason or his murder——”

“But your duty as a citizen——”

“Look here, what do you mean? Where was any duty? You people—you police people knew the shots were fired, didn’t you? Then why should I inform anybody that they were? And that’s all I knew—or know about them. They were fired. I heard them. No more.”

The sharp-featured, sharp-tongued old maid sat bolt upright in her chair, and glared at Belknap. Her hair was drawn up in a tight knot, after the fashion of New England spinsters, and Belknap wondered what it was about her appearance that seemed so strange.

For the rest, Miss Adams was angular, even gaunt, and apparently of a decided and forceful nature. And her testimony might be valuable.

“Your knowledge is of importance,” he said, gravely. “To be sure we know the shots were fired, but a witness is always of interest. What time was it that you heard the shots?”

“I’ve no idea,” she returned, carelessly. “Oh, I know, in the story books, the witness always knows, because he was just going to keep an engagement—or, setting his watch, or something. But I don’t know at all.”
