Poirot shrugged his shoulders.
"I may be wrong."
"So we come to the favour I want to ask you. Will you act in this matter for me?"
"For you personally?"
"That was my meaning."
Poirot was silent for a moment or two. Then he said:
"You realize what you are asking?"
"I guess so," said Van Aldin.
"Very well," said Poirot. "I accept. But in that case, I must have frank answers to my questions."
"Why, certainly. That is understood."
