“God, man, can’t you understand I’m working on a case?” Shayne burst out with harsh impatience. “Drake is the man I’ve been looking for — the man I was warned against when I took the case. The girl is Barbara Little. Margo Macon was strictly a phony name. Her father sent me here to guard her against a man who answers Drake’s description in every respect. He’s a dope-head and has had a vicious influence over the girl in the past. She broke away from him, cured herself of the habit, then got frantic when she felt the urge returning. She ran away from home and came here. Her father was afraid he’d find her and drive her back into the habit or to suicide or worse. This man Drake contacted Captain Denton yesterday, asking where such a girl might go in the Quarter to get back on the stuff. Well, he seems to have got to her as soon as I did,” he ended angrily.

Quinlan drove slowly. The quizzical, puzzled expression seemed permanently fixed on his finely chiseled features. “How do you know Drake had contacted Denton?”

“Denton told me so. I went to ask him the same question — that is, to get in touch with the dope traffic in the Quarter. I already knew who the girl was and where she lived. Denton got scared, and mad, when I told him Chief McCracken had sent me, and threw me out.”

Quinlan drummed his finger tips on the steering wheel. “You say the girl’s father knew Drake was here?”

“I don’t think he knew it, but he was afraid Drake might try to follow her. He intimated his fear of rather horrible depravities the girl might be led into, without giving any details.”

Quinlan nodded. He said dryly, “Drake doesn’t look so sinister.”

Shayne moved his big hands impatiently. “You know as well as I that you can’t judge the morals of a narcotic user by his appearance. They’re sly.”

“Is it your idea,” Quinlan asked suddenly, “that Drake murdered the girl?”

“Somebody murdered her,” Shayne argued. “Mr. Little had some such fear. It seemed to be an obsession with him. He hinted Drake had threatened her life the other time she pulled away from him.”

Quinlan sighed and said, “It sounds like a ten-cent melodrama.”
