QUOTE : There were several things to chew on, but of course the main one was Bingham’s alternatives. If he had known Carol Mardus as well as he said he did there were just four candidates. Even if he had killed her himself, he would name the ones she would have been most likely to pick if she hadn’t picked him, so it was highly probable that it was one of those four. I stood at a window, and sat at my desk, and stood some more, going over them. Which one? That’s the silliest game of solitaire there is, and we all play it, trying to tag a murderer as one of a bunch from what they said and how they looked and acted, unless you can spot something that really opens a crack. I couldn’t.
