With your quick intelligence you have spotted that the coming clean of Trout if the one thing that was needed to extricate you from the soup in which you are wallowing. It gives verisimilitude to an otherwise bald and unconvincing narrative. I go to her and say, "Hello there, Miss Fitch, I'll bet you've been wondering why Joe asked you to dinner and didn't turn up. The matter is readily explained. Somebody gave him a Mickey Finn," and it carries little or not conviction. But it's very different when Trout, tapping his chest, says, "I dun it." She swallows his story whole and asks for more.
