In Series One, Episode Two of  Sherlock, Sherlock Holmes enters the apartment of a stockbroker he suspects has been murdered and opens the fridge to reveal at least 7 bottles of Bollinger Special Cuvee.

Seconds later he discovers in a bedroom the body of the man whose demise appears to be the result of suicide.

Using his superhuman attention to detail and a form of reasoning (‘abductive’, apparently) he decides correctly the stockbroker was murdered.

Of course he was. Who would kill themselves when there are seven bottles of Bollinger in the fridge?!
