If you would like to have another try at your detective skills then feel free to answer this little puzzle.
A young boy is travelling in a car with his dad when they are involved in a serious accident and the dad is killed. The young boy is rushed to hospital whereby the surgeon in the operating room turns to the nurse and says "I cannot operate on this boy he is my son" Answers please
