Modern readers of Dorothy Sayers' excellent mysteries frequently have trouble identifying the source of the quotations she liberally drops into her stories, often as a chapter heading. There are two reasons for this problem.
1) Modern readers are sadly deficient in their literary education compared with someone like Sayers. Therefore, modern Americans who have been educated by the government schools might understand references to James Bond or The Mary Tyler Moore Show but few will note, for example, that the term "shabby tigers" (which Sayers uses in Busman's Honeymoon) comes from Ralph Hodgson's poem "The Bells of Heaven."
2) A second reason that a reader might be unable to trace one of the quotations Dorothy Sayers places in her mysteries? She sometimes invented them herself!
