[00:19.20]'At the time the murder was committed I was travelling on the 8 o'clock train to London,' said the man. [00:28.62]'Do you always catch such an early train?' asked the inspector. [00:34.94]'Of course I do,' answered the man. [00:38.80]'I must be at work at 10 o'clock. [00:42.39]My employer will confirm that I was there on time.' [00:48.09]'Would a later train get you to work on time?' asked the inspector. [00:55.17]'I suppose it would, but I never catch a later train.' [01:01.97]'At what time did you arrive at the station?' [01:06.74]'At ten to eight. I bought a paper and waited for the train.' [01:14.38]'And you didn't notice anything unusual?' [01:19.52]'Of course not.' [01:22.72]'I suggest,' said the inspector,' that you are not telling the truth. [01:29.23]I suggest that you did not catch the 8 o'clock train, [01:34.06]but that you caught the 8.25 which would still get you to work on time. [01:41.02]You see, on the morning of the murder, the 8 o'clock train did not run at all. [01:48.29]It broke down at Ferngreen station and was taken off the line.'
