We came back to the dining-room. Poirot had not accompanied us in our tour. I found him studying the centre table with close attention. I joined him. It was a well-polished round mahogany table. A bowl of roses decorated the centre, and white lace mats reposed on the gleaming surface. There was a dish of fruit, but the three dessert plates were untouched. There were three coffee-cups with remains of coffee in them⁠—two black, one with milk. All three men had taken port, and the decanter, half-full, stood before the centre plate. One of the men had smoked a cigar, the other two cigarettes. A tortoiseshell-and-silver box, holding cigars and cigarettes, stood open upon the table.

I enumerated all these facts to myself, but I was forced to admit that they did not shed any brilliant light on the situation. I wondered what Poirot saw in them to make him so intent. I asked him.
