"No," said Mack, his temper slowly rising.
"But you're willing to admit that a knowledge of Grinnell plays and signals would be highly valuable to your brother, aren't you?"
Mack glared. "I suppose they would ... but if you think my brother would take any underhanded advantage...!"
"We're not thinking," interrupted Detective Greene, smoothly. "We're just talking out loud. I believe you've been peeved at your Coach for some time ... even accused him of not giving you the breaks you deserved!"
"That's right," said Mack, after a moment's hesitation. "And I want to apologize for that."
"You do, eh?... What for?"
"Because I discovered last night I was wrong."
"Last night?"
"I mean—yesterday afternoon ... in scrimmage. I thought I was better than I really was. I'm sorry I ever said anything, Coach."
Coach Edward nodded, exchanging glances with the two detectives.
