*BONG* The huge grandfather clock in the foyer rings out twelve times, signalling that the time is now midnight.
Seargeant Teal was getting nowhere. Whomever Mr. Grey's killer had been, he--or she--had fiendishly concealed all evidence of the crime. There were no fingerprints, no telltale signs of struggle, no dried drops of blood, no huge flashing neon signs saying "Mr. X did it." He glanced at his wristwatch with a frown--if the investigation had not turned up anything substantial by sunrise, they would have to release the suspects.
He was rudely and abruptly startled by Detective Navy, who soberly informed him that another dead body had been found, this time in the Master Bedroom. He raced there, to discover the prone and lifeless body of the Red Baron.
"Our killer has struck again, it seems," said Teal, with a mounting sense of panic. "And right under our noses, too. Well, one thing we know, for sure--the killer was in the Master Bedroom this last hour."
"Er, not necessarily, sir," said Detective Navy. "We have discovered secret passages leading to both the Library and the Trophy Room. The killer could have been in either of those rooms as well."
