Ψυχογιός 23840 ο Γριφος του Παπουτσιου με την Αγκραφα

No, my friend, I'm not drunk. It is that I have just come out of the dentist and will not have to visit him again in the next six months. And this is a beautiful thought. A dentist is found dead with a small burning hole in his right-handed timer. On the floor, next to his outstretched right hand, there is a small pistol. Shortly afterwards, one of his patients died - from a lethal dose of local anesthetic. Is it a clear case of murder and suicide or something else, more serious, is it hiding behind this strange affair? But why does the dentist commit a crime and then commit suicide during a day full of professional appointments? Will Poirot be able to find the solution to the puzzle hidden in a shoe?
