At a dinner party, the host was poisoned with cyanide slipped into his wine glass. Four guests had access: the butler, the chef, the wife, and the business partner. The wife claimed she was pouring tea; the chef claimed he was testing soup; the business partner claimed he was checking his watch; the butler claimed he was dusting the chandelier. Detective Hayes arrested one of them instantly. Who and why?
The business partner
Cyanide kills almost instantly upon ingestion. The business partner claimed he was 'checking his watch' at the exact moment of ingestion, meaning he was staring directly at the victim when it happened and did nothing to stop or help him.
