Detective Vance found the victim slumped over a desk with a punctured chest and a half-eaten sandwich. There were no weapons in the room, but the thermostat was set to 90 degrees and ice water was dripping from the ceiling vent. How did the killer strike?
An icicle
The killer used a large icicle as a weapon. Because the room was heated to 90 degrees, the icicle melted completely, leaving no murder weapon behind and causing water to drip from the ceiling vent.
