Van Aldin did not answer for a minute or two, then he said:
"I don't exactly know what his intentions were."
"Did you hold any further communications with him?"
Again a slight pause, then Van Aldin said:
"No."
Poirot stopped dead, took off his hat, and held out his hand.
"I must wish you good-day, Monsieur. I can do nothing for you."
"What are you getting at?" demanded Van Aldin angrily.
"If you do not tell me the truth, I can do nothing."
"I don't know what you mean."
