"Imagine the nerve of that thief!" said Ralph Jameson. "While we were cleaning up after Thanksgiving dinner, he crept into our bedroom and stole all our antique silver! When we came into the room, the window was open and the silver was gone!"
Captain Black leaned out the window to look at the rooftop next door
"Most unpleasant, to have this happen on a holiday," the Captain said. "Was the collection valuable?"
"Yes, but that's not important," said the weeping Sally Jameson. "I'm worried about our safety. We've been afraid to go out since we discovered this. We just called the police and locked our door."
"Maybe we should have a cup of coffee," suggested Black.
The three went to the apartment's very clean, very neat kitchen. The Captain threw his chewing gum into an empty garbage can and quietly sipped his coffee.
"Tell me, Mr. Jamesone, have you left your apartment today for any reason at all? Even for a brief moment?"
"No, we were here all day before dinner, and afterwards we were afraid to go out...."
"You haven't fooled me with this silly lie!" the Captain snapped. "Now tell me the truth!"
~How did he know the Jamesons had lied?~
