"True. Well, I think, with a hypodermic needle, the poison could be got into the mint."
"Maybe, but I doubt it. However, I don't know much about such things. You're doubtless experienced."
"Yes, I've had a lot of poison cases. And, if we give up all thought of the soda mint, it does come back to a drink of some sort mixed by Thorpe."
"Or Blair might have mixed his own drink, and Thorpe added the poison, unnoticed."
"But I want to get away from Thorpe," Zizi said, her eyes anxious and worried.
"So do we all," returned Shelby gravely. "But where can we look?"
"Where, indeed?" echoed Penny Wise.
