Police!!!

After a moment's silence we three men ventured to look sideways at each other. We had certainly killed Professor Bottomly, scientifically speaking. The lady was practically dead. The morning papers would consummate the murder. We didn't know whether we wanted to laugh or not. She was now virtually done for; that seemed certain. So greedily had this egotistical female swallowed the silly bait we offered, so arrogantly had she planned to eliminate everybody excepting herself from the credit of the discovery, that there seemed now nothing left for us to do except to watch her hurdling deliriously toward destruction. Should we burst into hellish laughter?
