Inspector Vance found the victim slumped over a desk with a punctured tea cup, a fresh ink stain on his right index finger, and a window blown wide open by a winter gale. Vance immediately arrested the secretary. How did he know she lied about being out of the room all morning?
The fresh ink
In a winter gale, ink dries almost instantly due to the freezing draft. A fresh ink stain proves the victim was writing just seconds before Vance arrived, contradicting the secretary's claim that she had been alone in the office tending to him all morning.
