Balance of probability.

盖然性原则

你肯定没和短发女人接触过
or, you know, a woman.

Stains show he's out of condition. He's sentimental

出汗说明他身体不好说他多愁善感
- because the hat has been repaired, three, four... Five times.

-因为这帽子被修补过三四 - 五次
Very neatly. The cost of the repairs exceeds that of the hat,

而且针脚很齐修补费超过了帽子本身价格
he's mawkishly attached to it. But actually more than that.

他异常地迷恋这个帽子但其实更严重
One or two patches would indicate sentimentality.

一两个补丁表明他是多愁善感
But five. Five's obsessive behaviour. Obsessive compulsive.

但有五个就表明他有强迫症
Hardly. Your client left it behind.

不可能你的客户忘记拿走帽子了
What sort of an obsessive compulsive would do that?

强迫症怎么会留下帽子
The earlier patches are extensively sun bleached,

最早的补丁都被晒褪色了
