First listen and then answer the question: What was wrong with the man's story?
"At the time the murder was committed, I was travelling on the 8 o'clock train to London," said the man.
"Do you always catch such an early train?" asked the inspector.
"Of course I do," answered the man.
"I must be at work at 10 o'clock. My employer will confirm that I was there on time."
"Would a later train get you to work on time?" asked the inspector.
"I suppose it would, but I never catch a later train."
"At what time did you arrive at the station?"
"At ten to eight. I bought a paper and waited for the train."
"And you didn't notice anything unusual?"
"Of course not."
"I suggest," said the inspector, "that you are not telling the truth.
I suggest that you did not catch the 8 o'clock train, but that you caught the 8.25 which would still get you to work on time.
You see, on the morning of the murder, the 8 o'clock train did not run at all. It broke down at Ferngreen station and was taken off the line."
