“Then it must have a catch you can turn off so that the door will open from either side even though it’s latched.”
“It did have a catch like that,” she explained, “but Mr. Benson had it fixed so’s it wouldn’t work. He said it was too dangerous,—I might go out and leave the house unlocked.”
Vance stepped into the hallway, and I heard him opening and shutting the front door.
“You’re right, Mrs. Platz,” he observed, when he came back. “Now tell me: are you quite sure no one had a key?”
“Yes, sir. No one but me and Mr. Benson had a key.”
Vance nodded his acceptance of her statement.
“You said you left your bed-room door open on the night Mr. Benson was shot. . . . Do you generally leave it open?”
“No, I ’most always shut it. But it was terrible close that night.”
“Then it was merely an accident you left it open?”
“As you might say.”
