RAFFERTY, IN DANGER of feeling sorry for Sarah Astell, was relieved when, later that day, with hindsight's godlike vision; he saw clearly an aspect of the case that he and Llewellyn had both missed. One that provided Sarah Astell with an even stronger and – from Rafferty's point of view, anyway – far more satisfying motive for murder. Greed.
This indication that she hadn't been prompted entirely by a misconceived but entirely understandable concern for Carstairs' reputation, instantly gave Rafferty much more relish for his job. Even better, Llewellyn would be annoyed that he'd spotted the large clues while missing the subtler ones. But, he cautioned himself, he'd better try to check his facts before he shared his suspicions with the Welshman. To this end, he picked up the phone.
