““Hercule Poirot went to bed thoughtful. He was fascinated by the problem of personality. To Edmunds, the clerk, Elsa Greer was a hussy, no more, no less. To old Mr Jonathan she was the eternal Juliet. And Caroline Crale? Each person had seen her differently. Montague Depleach had despised her as a defeatist-a quitter. To young Fogg she had represented Romance. Edmunds saw her simply as a ‘lady’. Mr Jonathan had called her a stormy, turbulent creature. How would he, Hercule Poirot, have seen her? On the answer to that question depended, he felt, the success of his quest. So far, not one of the people he had seen had doubted that whatever else she was, Caroline Crale was also a murderess.””
