A wealthy eccentric was found dead in his study, sitting in front of a running fireplace. The room was locked from the inside. On the desk was a cup of hot cocoa and a handwritten suicide note. Detective Sterling felt the cup of cocoa, checked the temperature of the room, and declared it a homicide. What discrepancy did he find?
The hot cocoa
A blazing fireplace would heat a closed room significantly, yet the cup of cocoa was stone cold, proving it had been sitting there much longer than the fire had been burning.
