A man was found dead in a locked penthouse suite on the tenth floor. A bottle of vintage wine sat on the table with two crystal glasses, both containing a few drops of wine. The balcony doors were locked from the inside. Detective Mercer checked the wine glasses, smelled the victim's breath, and announced that the killer was a person who never drank alcohol. Why?
The second glass was untouched by lips
While there were two glasses, the second glass had wine poured into it to stage a meeting, but the rim of the second glass showed zero lip prints or saliva residue, proving the victim was alone and the killer staged the second glass.
