"You'd be guarded if you looked like being pinched for murder."
She let her monocle drop. "Neville, do you think there's a danger of that?"
"I do, of course. What is more, I don't think that the further instalment of Helen's adventures on the fatal night are going to be as helpful to John as she no doubt felt they would be."
"No," said Sally bluntly. "Nor do I. If she'd only keep her mouth shut . By the way, John doesn't know anything about her second interview with the Superintendent, so don't go and let it out!"
"How simple life would be without friends! Why, in the name of all that's feeble-minded -'
"Because he'd be bound to ask why she went back to the study, of course, and that would tear the whole thing wide open. She'd have to tell him about the IOUs."
"Let's go and write an anonymous letter to John, divulging the whole story, shall we?" suggested Neville. "It would be a kindness to them both, and I don't in the least mind doing people kindnesses if it doesn't cost me anything."
Sally sighed. "I darned nearly told him myself, when he first arrived. Only Helen was so terrified of his knowing that I didn't. And since then… Oh, I don't know! She may be right. I can't make John out. Neville, what brought him home?"
"Dear heart, will you purge your mind of the belief that I'm good at riddles?"
"He doesn't suspect her of having had an affair with Ernie. Apparently he told her he didn't."
