“Done.”
“Bolt the back door.”
“Done.”
“Good.” He addressed them: “An inspector, a lieutenant, and a sergeant of police have this building under siege. Since they are investigating murder, and since all of the persons involved have been collected here by me and they know it, my bolted doors will irritate them almost beyond endurance. I shall let them enter when I am ready, not before. If any of you wish to leave now, Mr. Goodwin will let you out to the street. Do you?”
Nobody moved or spoke, or breathed.
Wolfe nodded. “During your absence, Archie, Dr. Brady stated that outdoors on that terrace, with a breeze going, it is not likely that the absence of the iodine odor would have been noticed by him, or by anyone. Is that correct, doctor?”
“Yes,” Brady said curtly.
“Very well. I agree with you.” Wolfe surveyed the group. “So X’s improvisation was a success. Later, of course, he replaced the genuine iodine in the cupboard and removed the bogus. From his standpoint, it was next to perfect. It might indeed have been perfect, invulnerable to any inquest, if the chimpanzee hadn’t poured some of that mixture on the grass. I don’t know why X didn’t attend to that; there was plenty of time, whole days and nights; possible he hadn’t seen the chimpanzee doing it, or maybe he didn’t realize the danger. And we know he was foolhardy. He should certainly have disposed of the bogus iodine and the piece of glass he had removed from Miss Huddleston’s bath brush when it was no longer needed, but he didn’t. He—”
“How do you know he didn’t?” Larry demanded.
“Because he kept them. He must have kept them, since he used them. Yesterday he put the bogus iodine in the cabinet in Miss Nichols’ bathroom, and the piece of glass in her bath brush.”
