“I don’t know what you mean, Michael,” she moaned. “Tell me you’re joking.”
“This key isn’t any joke,” he told her harshly. “It’s going to unlock the death chamber for you, and you know it. I’m afraid we can’t touch you for shooting Ted Granger. You’re the only one who can testify as to what happened in that locked room. But you’ll never talk yourself out of murdering your husband, Nora. It just isn’t in the books.”
She slowly brought her emotions under control, sat back rigidly erect, and stared at him.
“I have no idea what you’re talking about,” she told him calmly. “No matter what absurd theory you have about Ralph’s death, I couldn’t possibly have gotten into his room, if I’d tried. You know, yourself, that’s the wrong key.”
Shayne said dispassionately, “You made one slip, Nora. One tiny slip in some of the neatest and fastest work to beat a murder rap I’ve ever run into. Why did you close my door on the night latch last night before coming to bed?”
“Because I thought you were Ralph. I’d left the door open to have a little light to see to undress. You can’t be serious,” she pleaded. “You’re just joking, and I don’t think it’s funny at all.”
“If I hadn’t been standing in the bedroom doorway, if I hadn’t seen you go to close the door, it might never have come to me. But I couldn’t get that picture of you out of my mind. You looked good,” he went on angrily. “So damned good that it kept coming back to me. And finally I realized the truth. You knew perfectly well you weren’t in Ralph’s apartment. Your whole story was a desperate lie to alibi yourself.”
“I don’t understand what you’re trying to get at at all,” she told him, her voice still calm and cold.
“Ludlow,” said Shayne grimly. “The photographer who was supposed to take a picture of you in bed with Ralph as clinching evidence to kill the divorce. We got it from Ludlow; and from Bill Nash, who was posing as Michael Shayne in the deal. You knew the setup. Everything was timed to the minute. They’ll testify you were to enter Ralph’s apartment at exactly two-ten. You were to leave the door ajar for Ludlow to follow ten minutes later, get undressed and into Ralph’s bed, and have the picture taken.
“And you did just that, Nora. The door was open for Ludlow at two-twenty. Ralph was there waiting for his picture, but you weren’t.”
