Deductive Thinking Puzzle 1
Nicole went to the police to report that
someone had stolen her vintage ring. When
the police got to her house they notice that
the window was broken, there was a total
mess inside, and there were dirty footprints
on the carpet. But, there were no other
signs of a break-in.
The next day, the police arrested Nicole for
fraud. Why?
Answer
As soon as the police got to the
“crime scene,” they knew that
Nicole has most likely staged the
break-in. The glass from the
broken window was all outside of
the house, meaning that it had
been broken from the inside.

A chemist was murdered in his own lab. The only evidence was a piece of
paper that had the names of chemical substances written on it. The

only had four people come by his lab on the day of the murder: fellow
scientist Claire, his nephew Nicolas, his wife, and his friend Marc. The police
arrested the murderer right away. How did they know who it was?

ANSWER.
A chemist was murdered in his own lab. The only
evidence was a piece of paper that had the names of
chemical substances written on it. The substances
were nickel, carbon, oxygen, lanthanum, and sulfur.
The chemist only had four people come by his lab
on the day of the murder: fellow scientist Claire, his
nephew Nicolas, his wife, and his friend Marc. The
police arrested the murderer right away. How did
they know who it was?
There was a very
obvious clue on the
piece of paper. If you
combine the
abbreviations of the
chemical substances
on the paper, you’ll get
a name: Ni-C-O-La-S.
