I was careful to get all the names spelled right in my notebook, since it seemed likely the job would be to get one of them tagged for murder, and I was especially careful with the last one that got in: Clara James, Gifford’s daughter. There were three spotlights on her. First, the reason for James’ assault on Mion had been his knowledge or suspicion — Fred and Peggy weren’t sure which — that Mion had stepped over the line with James’ daughter. Second, her name had ended the list, got by Fred from the doorman and elevator man, of people who had called that afternoon. They said she had come about a quarter past six and had got off at the floor the studio was on, the thirteenth, and had summoned the elevator to the twelfth floor a little later, maybe ten minutes, and had left. The third spotlight was directed by Peggy, who had stayed in the park a while after Fred had marched off, and had then returned home, arriving around five o’clock. She had not gone up to the studio and had not seen her husband. Sometime after six, she thought around half-past, she had answered the doorbell herself because the maid had been in the kitchen with the cook. It was Clara James. She was pale and tense, but she was always pale and tense. She had asked for Alberto, and Peggy had said she thought he was up in the studio, and Clara had said no, he wasn’t there, and never mind. When Clara went for the elevator button, Peggy had shut the door, not wanting company anyway, and particularly not Clara James.

Some half an hour later Fred showed up, and they ascended to the studio together and found that Alberto was there all right, but no longer upright or intact.

That picture left room for a whole night of questions, but Wolfe concentrated on what he regarded as the essentials. Even so, we went into the third hour and the third notebook. He completely ignored some spots that I thought needed filling in; for instance, had Alberto had a habit of stepping over the line with other men’s daughters and/or wives, and if so, names please. From things they said I gathered that Alberto had been broad-minded about other men’s women, but apparently Wolfe wasn’t interested. Along toward the end he was back on the gun again, and when they had nothing new to offer he scowled and got caustic. When they stayed glued he finally snapped at them, “Which one of you is lying?”

They looked hurt. “That won’t get you anywhere,” Fred Weppler said bitterly, “or us either.”

“It would be silly,” Peggy Mion protested, “to come here and give you that check and then lie to you. Wouldn’t it?”

“Then you’re silly,” Wolfe said coldly. He pointed a finger at her. “Look here. All of this might be worked out, none of it is preposterous, except one thing. Who put the gun on the floor beside the body? When you two entered the studio it wasn’t there; you both swear to that, and I accept it. You left and started downstairs; you fell, and he carried you to your room. You weren’t unconscious. Were you?”

“No.” Peggy was meeting his gaze. “I could have walked, but he — he wanted to carry me.”

“No doubt. He did so. You stayed in your room. He went to the ground floor to compile a list of those who had made themselves available as murder suspects — showing admirable foresight, by the way — came back up and phoned the police and then the doctor, who arrived without delay since he lived in the building. Not more than fifteen minutes intervened between the moment you and Mr. Weppler left the studio and the moment he and the doctor entered. The door from the studio to the public hall on the thirteenth floor has a lock that is automatic with the closing of the door, and the door was closed and locked. No one could possibly have entered during the fifteen minutes. You say that you had left your bed and gone to the living room, and that no one could have used that route without being seen by you. The maid and cook were in the kitchen, unaware of what was going on. So no one entered the studio and placed the gun on the floor.”

“Someone did,” Fred said doggedly.

Peggy insisted, “We don’t know who had a key.”
