See if You Can Pass the FBI Special Agent Test (Part 2)

3. Murder at home

A man was found murdered on a Sunday afternoon. At the time of the murder there were four people in the house. The wife, the cook, the maid, and the gardener. The police were called to investigate the murder. Everybody told the police what they were doing.

The wife said “I was reading a book”

The cook said “I was cooking breakfast”

The maid said “I was fixing the table”

The gardener said “I was watering the plants”

After listening the statements, the police arrested the murderer.


Who is the murderer and how did the police know?


The cook did it.

You don’t cook breakfast in the afternoon.


4. Stolen money

A man placed a $100 bill on the table and left for work. When he returned, the money was gone. He has three suspects: the cook, the maid, and the electrician.

The cook said “I put the bill under a book to keep it safe,” the man checked and it was not there.

The maid said “I moved the bill inside the book between page 10 and 11 to keep it safe,” the man checked the book and there was nothing between pages 10 and 11.

The electrician said “I saw the bill sticking out of the book and I moved it between pages 11 and 12 to keep it safe.”

The man immediately knew who stole the money.


Who is the thief?


The electrician stole the money.

If the man checked for the money between pages 10 and 11 of the book, then pages 11 and 12 will be opposite sides of a single sheet and the electrician simply was not able to do what he said.


5. Frost on windows

Ben was found dead in his study by his friend John. John called the police and told them what happened. He said “I was walking by Ben’s house and saw light on in his room. I decided to look from outside to see if he was there. There was frost on the window, so I wiped it and that’s when I saw the body. I kicked the front door in to check things out and found that my friend was dead. I called police immediately.”

The officer knew immediately that John was lying.


How did the detective know?


Frost forms on the inside of the window, not the outside. So John could not have wiped it off to find his friend.
