“Don’t ask me about it,” continued Miss Howard, “because I shan’t tell you. I won’t admit it, even to myself. I must be mad to think of such a thing.”
Poirot nodded, as if satisfied.
“I will ask you nothing. It is enough for me that it is as I thought. And I—I, too, have an instinct. We are working together towards a common end.”
“Don’t ask me to help you, because I won’t. I wouldn’t lift a finger to—to——” She faltered.
“You will help me in spite of yourself. I ask you nothing—but you will be my ally. You will not be able to help yourself. You will do the only thing that I want of you.”
“And that is?”
“You will watch!”
Evelyn Howard bowed her head.
“Yes, I can’t help doing that. I am always watching—always hoping I shall be proved wrong.”
“If we are wrong, well and good,” said Poirot. “No one will be more pleased than I shall. But, if we are right? If we are right, Miss Howard, on whose side are you then?”
