"Bang up," murmured O'Connor.
"Take another along," suggested Forrester, accepting the hint.
The two detectives each carefully selected another cigar, and then Forrester went with them to the door.
"What will you do if the ghosts supposed to haunt that tree should appear?" inquired Forrester.
"You don't believe that stuff, do you, Mr. Forrester?" asked Cahill, scornfully.
"Well, several people, unknown to one another, have agreed on the details."
Cahill smiled. "Maybe so," he said, "but don't forget that O'Connor and me can shoot, Mr. Forrester. We can lay out any ghost that ever ghosted."
"You certainly have my best wishes for your success," said Forrester.
"Don't worry any more," assured Cahill, as he passed out. "The police have got this gang dead to rights this time. Saturday night will end it!"
