A wealthy merchant was found poisoned in his locked study. On the mahogany table sat three wine glasses: one half-full of red wine, one empty, and one containing a mysterious clear residue. The butler stated the merchant poured himself a glass of red wine at 8:00 PM and never touched another bottle. Detective Miller looked at the glasses and arrested the cook. Why?
The merchant drank alone but there were two used glasses plus the residue
If the merchant only poured one glass of red wine at 8:00 PM, there should only be one glass used. The presence of multiple glasses points to someone else being in the room.
