While participating on the
Agatha Christie panel at the Murder, Mystery, and Mayhem event this year, we
discussed Christie’s fascination with using poisons to kill many of her
characters. Thanks to her work as a nurse and a pharmacy dispenser during World
War I, her knowledge of poisons was extensive.
In her first novel, The Mysterious Affair at Styles,
strychnine is featured, and it is described as an ideal poison for
a writer due to its rapid onset and dramatic effects. But the poison she used
most frequently is Cyanide, appearing in And Then There Were None and
The Mirror Crack’d from Side to Side. In other books, victims die from
arsenic, digitalis, and morphine.
However, Christie was not the first writer to introduce poison
in a mystery novel. She just used them with such incredible detail, that a reader
could learn about a new poison and its effects instantly. This method made her
novels quite sophisticated to readers during the Golden Age of Detective
Fiction in the 1920s and 1930s, which is often referred to as the Golden Age of
Poisons, largely due to Christie and her contemporaries who used toxins to dispatch
characters in their novels.
The panel discussion continued with the methods of murder that
mystery writers use today to bring about a character’s demise. These include
stabbings, shootings, blunt objects, fire, drowning, and strangulation.
However, the
use of poison still continues in culinary mysteries and other genres. Writers
use plant poisons such as hemlock, lily of the valley, poisoned mushroom,
Nicotine, and Oleander. Drugs and medicine include insulin, sedatives, Tylenol,
and Fentanyl. All of which are fascinating to today’s mystery readers.
Since Agatha Christie was a "pick your poison" writer and most likely had fun with it, in many ways, poison became a personality in her stories which is almost a cliché today. But her novels live on due to her well-crafted plots, interesting characters, and realistic descriptions of the toxin's symptoms, which is why she is crowned "The Queen of Crime."
