课文内容：

'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.'

参考翻译：

“在凶杀发生的时候，我正坐在8点钟开往伦敦的火车上。”那人说。

“您总是赶这样早的火车？”探长问。

“当然是的，”那人回答。“我必须在10点钟上班，我的雇主会证明我是按时到了那儿的。”

“晚一点儿的车也能送您按时上班吗？”

“我认为可以，但我从来不乘晚一点儿的车。”

“您几点钟到的火车站？”
