"I did not--I did not."
"I guess you did," said Tracey; "see here, professor, what's the use of slinging lies? I guess we've got the bulge on you this trip. Mrs. B.'s diary gave away the whole thing, and now we have come to ask what you were doing in the house on the night of the murder?"
"Or, to put it plainly," said Arnold quietly, "why you killed Flora?"
Bocaros, as Fane had done before him, leaped to his feet. "I did not kill the woman! I swear I did not."
"Fane said the same thing."
"But Fane did. He was in the house."
"How do you know that?" asked Luther; and Bocaros, seeing he had gone too far, was silent. "I reckon," went on the American, "that this is what the law calls a conspiracy. You've been building up card-castles to get that money, and they've tumbled. Now it's our turn to threaten to make things public, professor, and if you don't speak out you will be arrested."
"I arrested!" gasped Bocaros, stepping back a pace.
"Yes--for murder," said Arnold solemnly.
"I did not kill her."
