A crime has been committed at Freemont Street. The main suspect is a man named Sean Baker. It was said that a man had been walking along the pathway when he was suddenly shot in the stomach. The suspect had brown hair, blue eyes and wore a baggy Armani suit just like Sean Baker’s. Sean was asked to tell the story right from the beginning. “Well,” said Sean, “I was just hanging around the park when I saw this man walking along the pathway. Suddenly, a guy came up from behind him and shot him! I ran home as fast as I could.” The policemen asked him to give a description of the murderer. “He had a red moustache, red hair and a baggy Armani suit on.” “I think this man is telling a lie,” said one of the policemen.

Lucretia Borgia invited a prospective victim to lunch. They ate a hearty meal of roast venison, with a selection of fresh vegetables, all washed down with the finest wine imported from Bordeaux in France. After the meal they finished off with figs and grapes freshly picked. “Just one apple left”, said Lucretia, “I insist you have that. “No”, said the guest, “I couldn’t”. “Tell you what”, said Lucretia, “we will share it”, and promptly sliced it neatly in two with her sharpest knife. The guest and Lucretia started to eat their respective halves when suddenly the guest’s eyes rolled towards the ceiling and he keeled over backwards stone dead. “Another victim successfully despatched,” thought Lucretia. Why was Lucretia not poisoned after eating the apple?

One murder happened in a village. A police officer instructed two police constables to go to the crime scene, investigate and prepare an preliminary incident report. It was already past midnight and the crime scene was far away from the police station. The two constables decided not to travel to the crime scene and came up with a fake incident report instead.

There were some items found on a table: – One open bottle of poison, – One half filled drinking water bottle, – One fountain pen, – One newspaper was flipped open, pages 9 and 10 facing each other, – One table top calendar showing June 20, – One notebook.

Six men, namely Martin Freeman, Jonah Jameson, Terry Singer, Mike Cooper, Jim Condon and Sylvian Bogard were in an elevator together. Unexpectedly, the lights went out. When the lights came back, Martin Freeman’s wallet was missing which contained a confidential item. Detectives were called at the scene.
