One of the themes of this story - Ruthlesness evolves from the possessiveness, and stinginess of the main character - Judson Webb.
The story summarized the cause of this death as arising from inadvertent self-poisoning.
Described as a short-tempered man with an inordinate obsession for his property especially his fishing equipment, guns, and liquor, Judson against his wife's pleas and advice poisons his own drink on the premise that a thief was stealing some of it.
He believes that it is "fair" for the thief to die for stealing.
Unfortunately, upon the occurrence of an accident where Judson slips and hits his head, his servant - Alec, (unaware that the poisoned bottle) administers some of the liquor to him to relieve the pain. This of course leads to Judson's demise.
