“Some people are much easier to read from than others. Lady Heritage is very easy. I’m sure I was not mistaken; she was saying, ‘If she overheard anything, would she have the intelligence to be dangerous? That is what I ask myself,’ and she said, ‘Despise not thine enemy,’ and ‘Anything but Formula “A.”’ Now Mr. Ember is very difficult. I can’t really make him out at all. His lips don’t move. It’s no use not believing me, Henry. Look here, I’ll show you.” She caught up the little torch, and turned the light upon his face. “Say something,” she commanded. Henry’s lips formed the words, “Jane, I love you very much indeed”—and Jane switched off the light. “Henry, you’re a perfect beast! Play fair,” she said, in a low, furious whisper. “Sorry. Wasn’t it all right? Try again.” Jane allowed the ray to light up Henry’s mouth and chin. The hand that held the torch was not quite steady. This may have been the result of anger—or of some other emotion. As a result the light wavered a good deal. Henry’s lips moved, and Jane read aloud, “A sleuth should never lose its temper.” Henry’s hand caught the little shaking one that held the torch, and gave it a great squeeze. “How frightfully clever you are, and—oh, Jane, what a goose!” “I’m not,” said Jane. “But don’t you see that, with Renata’s story in your mind, you would be looking out for things? You couldn’t help it.” “What do you think, then, of Lady Heritage saying that Mr. Ember’s verdict was inclined to be ‘Guilty, but recommended to mercy,’ whereas she said that she herself doubted the guilt, but that if she did not, she would have no mercy at all? Do you know, that frightened me almost more than anything. I don’t know why. That wasn’t lip-reading; I heard the words with my own ears.” “But—don’t you see——” He paused. “Let’s get back to facts: Formula ‘A’ has been stolen and offered for sale. Renata, undoubtedly, overheard something relating to Formula ‘A.’ Now, supposing Mr. Molloy or one of his friends to be the person who is doing the deal, don’t you see that the possibility of Renata having overheard something compromising would be sufficient to account for a good deal of alarm? “If Molloy and his friends had stolen Formula ‘A’ and were trying to dispose of it, it would naturally be of the highest importance to them to find out how much Renata knew, and to take steps which would ensure her silence. They would almost certainly try and frighten her—that’s how it seems to me.” “Then where does Mr. Ember come in?” said Jane. “He was there.” “Are you sure?” “Renata described him,” said Jane. “She said he was the worst of them all.” “She knew him by name?” “No. But ... but”—a little chill breath of doubt played on Jane’s certainty—“she called him the man in the fur coat. The others spoke of him as Number Two.” “But you don’t know that it was Ember?”
