Champagne for One

"It could have been. With her character and temperament that could have been sufficient motive. But she has herself just suggested an additional one. Her nephew may have been using Faith Usher as a fulcrum to pry a fortune out of her. You will explore that."

"I certainly will. That show you put on. You say that proved that Mrs Robilotti could have done it?"

"Yes. You saw it. She could have dropped the poison into the glass that had been standing there for three or four minutes. She stayed there at the bar. If someone else had started to take that glass she could have said it was hers. When her son came and picked up the two glasses, if he had taken the poisoned one in his right hand, which would have meant-to her, since she knew his habits-that he would drink it himself, again she could have said it was hers and told him to get another one. Or she could even have handed it to him, have seen to it that he took the poisoned one in his left hand; but you can’t hope to establish that, since neither she nor her son would admit it. The moment he left the bar with the poisoned glass in his left hand Faith Usher was doomed; and the risk was slight, since an ample supply of cyanide was there on a chair in Miss Usher’s bag. It would unquestionably be assumed that she had committed suicide; indeed, it was assumed, and the assumption would have prevailed if Mr Goodwin hadn’t been there and kept his eyes open."

"Who told Mrs Robilotti that Miss Usher had the poison? And when?"

"I don’t know." Wolfe gestured. "Confound it, must I shine your shoes for you?"

"No, I’ll manage. You’ve shined enough. You say the risk was slight. It wasn’t slight when she got Miss Usher’s bag and took out the bottle and took some of the poison."

"I doubt if she did that. I doubt if she ever went near that bag. If she knew that the poison Miss Usher carried around was cyanide, and several people did, she probably got some somewhere else, which isn’t difficult, and had it at hand. I suggest that that is worth inquiry, whether she recently had access to a supply of cyanide. You might even find that she had actually procured some." Wolfe gestured again. "I do not pretend that I am showing you a ripened fruit which you need only to pick. I undertook merely to satisfy myself whether Mr Goodwin was right or wrong. I am satisfied. Are you?"
