Bo Sawchuk:  You 're saying Shepherd wants to frame your dad ?
Shirley Holmes: Shepherd 's job is on the line if he does n't arrest someone . He hasn't found the real culprit , so he could be setting up my dad to save his own hide .
Bo Sawchuk: Yeah , but he 's a spy catcher , not a spy .
Shirley Holmes: You need to think like one to catch _ one _ .
