"It looks very innocent," Kalmon answered. "Here it is."

He took a small leather case from his pocket, opened it, and drew out a short blue glass tube, with a screw top. It contained half a dozen white tablets, apparently just like those in common use for five-grain doses of quinine.

A little murmur of disappointment went around the table. The new form of death looked very commonplace. Corbario was the only one who showed any interest.

"May I see?" he asked, holding out his hand to take the tube.

Kalmon would not give it to him, but held the tube before his eyes under the bright light of the lamp.

"Excuse me," he said, "but I make it a rule never to let it go out of my hands. You understand, don't you? If it were passed round, some one might lay it down, it might be forgotten, somebody might take it for something else."

"Of course," said Folco, looking intently at the tube, as though he could understand something about the contents by mere inspection. "You are quite right. You should take no risks with such things—especially as they look so innocent!"

He leaned back in his chair again, as if satisfied, and his eyes met the Contessa's at the same moment. There was no reason why she should not have looked at him just then, but he rested one elbow on the table and shaded his eyes from the light.

"It is strange to reflect," said Kalmon, looking at the tube thoughtfully, "that one of those little things would be enough to put a Hercules out of misery, without leaving the slightest trace which science could discover."

Corbario was still shading his eyes from the light.
