"What sort of sounds?" he asked.
"There were two," replied the cab driver. "The first was a revolver shot; the second came right after, and was a kind of a scream—like that of a parrot."
"And what then?" asked Ashton-Kirk, easily.
"There wasn't anything for a few minutes, anyway. But the revolver shot had kind of got my attention, so I was taking notice of the windows. Then suddenly I caught sight of the woman. You see, the gas-light was near the window and she kind of leaned over and turned it out. It was only for a time as long as that," and the man snapped his fingers. "But I saw her plain. Then I heard her coming down the stairs to the street—almost at a run. She banged the street door shut after her, jumped into her car and went tearing away as if she was crazy. I stayed fifteen minutes before I got a fare; but nothing else happened."
Pendleton's hand closed hard on the edge of the chair he sat in. There was a moment's silence; then Ashton-Kirk asked:
"Just where was your cab standing at this time?"
"Right in front of McCausland's door."
"And you were on the box?"
"Yes."
The investigator put a piece of money in the man's hand as he and Pendleton arose and prepared to go.
