Poirot Bk : Double Sin and other stories (1/5)

Double Sin

Mystery: Poirot met Mary Durrant on a coach. They had lunch together at a peak stop. Mary Durrant ran after a man whom she thought taking her suitcase. However, Mary Durrant she found that his suitcase was not hers. Just when she thought everything seems fine, she found out that her dispatch suitcase's lock was broken and it's content, the valuable miniatures was stolen. The miniatures have managed to reach the designated buyer's hand 30 minutes before Mary reached the station where she wanted to meet the buyer, Mr J.Buklet Wood. An old tall woman, with grey hair brought the minatures, and sold them to Mr J.Buklet Wood.

Victim: Mary Durrant is working for her Aunt, Miss Penn, trading valuable miniatures. Miss Penn, was old lady but wheel chair bounded. The stolen miniatures worth 500 pounds.
- She seems to be foolish to confide to strangers about her assets and her purpose of travel so quickly. (Thinking that theif will only steal money)
- Her Aunt have had a rough time taking over the business left behind by her late father. However, she became successful in this business.
- When she was in the resturant having lunch, she saw a man taking a suitcase which was similiar to hers through the window.

Suspects:
1) Mr Nortan Kane, a rude man with a grown moustache, had alighted early at the peak stop despite paying for the full ride. He was seen by Mary taking his own suitcase from the coach at the peak stop. He could have overheard easily about the value of the miniatures from Mary. He met a lady at the peak stop and drove a fast car. It seems possible for them to steal the miniatures and went on a fast car to sell them to Mr Wood before Mary.
2) Mr J.Bucklet Wood, rich and ostentatious man, could have gotten someone to steal the miniatures and lie about buying the miniature with good faith.

Curious:
->Mr Nortan Kane took something from his luggage shortly after he put his in while the rests are eating lunch.
-> Mary sitting facing the window in a restaurant, not a feminine manner.
-> The thief would have stolen the whole dispatch suitcase contenting the miniatures from Mary's luggage, rather than spending the effort of breaking the lock of the dispatch suitcase.

Leads:
The return trip is faster because the coach goes in a loop.
