A wealthy merchant was found poisoned in his locked study. There were no signs of forced entry. On the mahogany table sat a half-empty glass of iced tea and a suicide note. Detective Gray examined the ice cubes in the glass and instantly knew it was murder, not suicide. Why?
The ice cubes were completely melted, meaning the drink had been sitting out for hours, yet the merchant had just been poisoned.
If the merchant had just drank the poisoned tea, the ice would still be frozen or partially frozen. Fully melted ice indicates the drink was left unattended long before the victim consumed it.
