How Not To Get Away With Murder

Lucas had just locked up, turning to leave, when he saw Inspector Drake and company approaching. Confident, he went into his act.
“Good morning, Inspector. What brings you here at this hour?”
“I think you know, Mr. Lucas.”
“I’m sorry, Inspector. I have no time for games.”
The Inspector pulled out a search warrant.
“I don’t either, Mr. Lucas.”
Turning back, Lucas opened up for them. They searched and found it.
BINGO! Match!
The Inspector approached him, holding up a pair of tweezers.
“Lucas, looks like you lost by a hair.”
Drake turned to his men.
“Book him, murder one.”
