"Where there is smoke, there is fire"

The proverb "Where there is smoke, there is fire" is often used metaphorically to suggest that evidence of a problem or scandal usually indicates the existence of a larger, underlying issue. It implies that signs or indications of trouble ("smoke") are rarely without cause and often lead to the discovery of a significant problem ("fire"). This saying serves as a cautionary note to pay attention to warning signs before they escalate into more serious problems. It encourages vigilance and investigation when there are hints or suspicions of something amiss. The essence of this adage is to not dismiss minor or initial signs of an issue, as they can be symptomatic of a much larger and more serious situation.
