Originally published in 1927, UNNATURAL DEATH is the third of Dorothy L. Sayer's "Lord Peter Wimsey" mystery novels--and a novel in which Sayers manages to strike the same balance of literary style and humor that she previously created in the 1926 CLOUDS OF WITNESS. But also like CLOUDS OF WITNESS, UNNATURAL DEATH is not a murder mystery per se--a fact that may annoy readers in search of a classic "whodunit" novel. In this instance, the criminal is a foregone conclusion; it is catching her that poses the problem.
That problem proves remarkably convoluted. Miss Agatha Dawson, an elderly lady of considerable wealth, has died after a long battle with cancer--a reasonable death. Even so, the doctor in charge of the case feels uneasy; not only did the death benefit Miss Dawson's great-niece considerably, it seemed to him a little premature. And when Lord Peter Wimsey becomes intrigued, it seems that any individual who could give evidence against the niece suddenly dies! This poses an unexpected moral issue for Wimsey. Should he continue to pursue the case--even though his persistence seems to force the killer to kill again or again?
