A story by a detective
So, one foggy November night, Mr. X, wearing a long overcoat, walked along a back street in Liverpool with a box under his arm. He came to a house, put his box down on the ground, and knocked at the door. When a man opened the door, Mr. X. picked up the box and gave it to him.

Two days later, Mr. X. read in the newspaper that a dead body has been found in a Liverpool park with its left arm missing and he was extremely shocked.
