“I tell you I don’t know.”

“And why can’t you tell your story to the police?”

“Because — because I’m afraid I’m in an awful jam, Mr. Mason. Sarah was the only one who could have vouched for me in case — well, in case the police turn up certain things.”

“And you want me to suppress all of this,” and Mason included the room and the body with a sweeping gesture of his hands, “simply in order to save you from being questioned by the police?”

“It isn’t going to hurt anything if you do this for me,” she said. “There’s nothing you can do to help solve this.”

Mason studied her thoughtfully. Abruptly, he asked, “This Mrs. Perlin, was she a woman who had had much experience as a housekeeper, or had she perhaps had money at one time, run into hard luck, and had to get work as a housekeeper...?”

“No. She’d been a housekeeper for years. I remember checking on her agency card when Mr. Hocksley hired her.”

Mason strolled down the corridor toward the dining room. His hands were pushed down in his pockets, his head thrust forward. She followed him, apprehensive, silently pleading. Abruptly, Mason whirled to face her. “You know what you’re asking?” he demanded.

She said nothing as he paused, her eyes pleading eloquently, her lips motionless.

“You’re asking me to square a murder,” Mason said, “to get my neck in a noose, and you’re doing it as casually as though you were wanting to know if I wouldn’t buy you an ice cream, or sign my name in your autograph album.”
