"That's nonsense," was my answer. "We're going to meet here to-morrow night to talk things over."

"But why?" he protested.

There is no activity more explosive than that of the chronic idler. Once out on Broadway, accordingly, I did not let the grass grow under my feet. Two minutes at the telephone and ten more in a taxicab brought me in touch with my old friend Doyle who was "working" a mulatto shooting case in lower Seventh Avenue as quietly as a gardener working his cabbage-patch.

"What do you know about a woman named Vinnie Brunelle?" I demanded.

He studied the pavement. Then he shook his head. The name clearly meant nothing to him.

"Give me something more to work on!"

"She's a young woman who lives by her wits. She keeps up a very good front, and now and then does a variety of the wire-tapping game."
