The brahmin who killed the loyal mongoose
A brahmin leaves his infant son in the care of a pet mongoose, which kills a snake approaching the cradle. When the brahmin returns and sees the mongoose's bloody mouth, he assumes it has killed the child and strikes it dead, only then to find the baby unharmed beside the torn snake. The tale shows how acting on the first vivid piece of evidence, without checking the scene, destroys the very protector who deserved reward.
