‘My dear, some people talk in their sleep. Typically, you’d like the reader to believe you write in yours. All I had to do was turn back to page 163. Butterflies turning into books! Books with such titles as
‘There’s something strange about a dream,’ she suddenly mused. ‘It may be anything at all it cares to be, it’s governed by no rules of logical or psychological verisimilitude. Yet, in a way I’m not wholly able to account for, a dream can also be
‘I admit you’ve constructed quite a case against me,’ I said fairly calmly, ‘even if it’s a case propped up on the wobbliest of circumstantial evidence. But, as dear old Trubshawe might have put it, haven’t you overlooked something?’
‘What have I overlooked? And, incidentally, I’d be greatly obliged if you would leave Eustace, God rest his soul, out of it.’
‘Haven’t you overlooked the fact that Slavorigin was invited to the Sherlock Holmes Festival as its Mystery Guest? That none of us was informed in advance of his attending it?’
‘Well, yes, I did at first wonder at that. As I just said, I distrust coincidences. But then a foolish notion occurred to me, although not so foolish I didn’t feel it worth following up.

‘When you took Slavorigin’s life, Gilbert, you not only broke the law, you not only broke the Fourth Commandment, you broke one of the cardinal rules drawn up for the Detection Club by Ronnie Knox. “The criminal must be someone mentioned in the early part of the story, but must not” – repeat,
‘It’s true,’ I dreamily replied, ‘I was such a weird child my parents thought I’d been adopted.’
‘I’m not surprised.’
‘Joke. It was a joke, Evie. But do go on. The suspense is killing me.’
‘Well, the single question whose answer continued to elude me was, of course,
‘You mean?’
‘I mean the Belgian agent from Interpol. He was, I fear, a letdown for all of us fans of Poirot and Maigret. A big strapping ginger-haired fellow with a crushing handshake and a sergeant-major’s bark, he bore as little resemblance to one as to the other.
