What was the strange thing about the narrator in I never forget a face?

It is the summarry here

Explanation:

The “I” in the story is a businessman with a weird ability of remembering faces but not the names of people. Once he saw a face, he never forgets them. This strange capability both helped him and got him into trouble. One day, he was late from work and was traveling back home in a train later than usual. It was then he saw a man get in from London. One look at him and the author knew that the man was from Bardfield like him although he didn’t know where he had seen his face there.

The train was quite crowded and the author smiled at the gentleman who returned it to him. However, their carriage soon became empty leaving only the two of them behind. The author tried to make conversation with him in many ways including about a business deal that he had made that morning. However, the man talked very little and soon the author gave up on him. Once, when he looked up at the man from his newspaper, the author found the man asleep.

When they reached their station, the author woke up his co-passenger and they walked outside the station. As it was dark and rainy, the author offered to drop the man home in his car if it was on the route that he took. The man thanked him and they resumed their journey together with the man remaining silent.

Half way through when they were at a deserted spot, the man said that he would get down there. The author thought that he was crazy but slowed down anyway. Suddenly, he felt a sharp blow on his head and he fell unconscious. He vaguely remembered being pulled out of his car. When the author regained consciousness, he had a bad headache and he found himself robbed of his car, wallet, umbrella and watch. Slowly, he made his way by foot to Bardfield and to the police station there.

When he reached the police station, the author remembered who the person was. There was a lookout notice posted on the wall that the author had seen daily for a week. The man was John and he was accused of robbery with violence and murder attempts. Once again, remembering just the face and not the name had landed the author in trouble.
