In "A Jury of Her Peers," a fictionalized version of a true ax murder, the method of murder is important because Mrs. Hale and Mrs. Peters, who make the discovery of the dead canary, are able to determine the motive for Mr. Wright's murder as clearly belonging to his wife.
The method of murder against Mr. Wright in Glaspell's story is strangulation. According to Mr. Hale, a neighbor of the Wrights, Mrs. Wright told him when he came over the day following the murder that her husband "... died of a rope around his neck." Then she looked at Mr. Hale with a frightened look.
It is not until Mrs. Hale and Mrs. Peters discover the hidden box in the kitchen that contains a canary which has had its neck wrung that they know the motive for the murder. The two women stare at each other in comprehension and horror. For, it must have been a very angry Mrs. Wright who slipped a rope around her husband's neck and was able to choke him. After her husband killed the only thing that brought her any joy, Mrs. Wright must have had a great deal of adrenaline flowing through her as she was enraged that her bird, the only thing that she could love and that could bring her joy, would be strangled.
