"Well, go and see," Venner said grimly. "Unless my eyes deceive me, the box is still lying on Fenwick's table. In his fright, he forgot all about it, and there isn't a waiter among the whole lot, from the chief downwards, who has a really clear impression of what the offence was. If you take my advice, you will go and have a peep into that box when you get the chance. Don't tell me what you find, because I will guess that."
Gurdon crossed over to the other table, and took the box up in his hand. He pulled the slide out and glanced at the contents with a puzzled expression of face. Then he dropped the box again, and came back to Venner with a look on his face as if he had been handling something more than usually repulsive.
"You needn't tell me what it is," Venner said. "I know quite as well as you do. Inside that box is a dried up piece of flesh, some three inches long—in other words a mummified human forefinger."
CHAPTER III
THE LOST MINE
Gurdon nodded thoughtfully. He was trying to piece the puzzle together in his mind, but so far without success. He was not in the least surprised to find that Venner had guessed correctly.
"You've got it exactly," he said. "That is just what the gruesome thing is. What does it all mean?"
By this time dinner had long been a thing of the past, and all the guests had departed. Here and there the lights were turned down, leaving half the room in semi-darkness. It was just the time and place for an exchange of confidences.
"How did you know exactly what was in that box?" Gurdon asked. "I have read things of this kind before, but they have generally taken the form of a warning previous to some act of vengeance."
"As a matter of fact, this is something of the same kind," Venner said; "though I am bound to say that my guess was somewhat in the nature of a shot. Still, putting two and two together, I felt that I could not have been far wrong. Since I have been here this evening, I have begun to form a pretty shrewd opinion as to where Fenwick gets his money."
