“我把来访的两位客人带进会客厅时,他已经死了。”死者的妻子说。死者是一位知名的画家,死因是被子弹击中头部。当时他的左手握着一支手枪,外表看来好像是死于自杀。查克斯探长展开调查,询问相关的人物。来访的两位客人,一个叫道明,是死者的旧相识,三年前去了巴黎,两天前才回来;另外一个叫小田,他也是画家,这几天一直到家中拜访死者,因为他觉得死者剽窃了他的作品,前来追究。 “I was already dead when I brought two guests to the drawing-room,” said the wife of the deceased. The deceased was a well-known painter who was hit by a bullet in the head. At that time, his left hand held a pistol, apparently seems to have died of suicide. Sergeant Chicks started investigating and asked relevant people. Two visitors, one called Taoism, were the old acquaintance of the deceased. They went to Paris three years ago and came back two days ago. The other, called Oda, is also an artist who has been home to visit the deceased for days. The deceased plagiarized his work, came to investigate.
