Agatha Christie, the murder-mystery writer, was married to an archeologist (she joked that “an archeologist is the best husband any woman can have; the older she gets the more interested he is in her”). Her husband wanted to visit the Roman ruins at Conimbriga, so the couple spent some time in Portugal. They chose the Bussaco Palace Hotel as their base and stayed in room number 7.
The romantic surroundings must have appealed to the mystery writer. But the only crime committed in this luxury hotel was the occasional spilling of a few drops of precious Bussaco wine. And there was no need to call Hercule Poirot because it was obvious that the butler did it.
