[1] Police Chief James A. Sullivan is in his office berating several people under his command who he feels are doing a less than top notch job.

His secretary, Kathleen Ryan, sends them in one by one except when Lieutenant Dan Burke arrives.

However, when the demonstration is over, the Chief, who was sitting in the front row, is found to be dead, possibly by a poison dart.

Prof. Graham establishes that the killer was Dan and his motive was the Chief's refusal to allow the wedding to proceed.

Dan and Claudia go out on a picnic and she is sad about all the recent events, especially about the fact that Graham had been executed for his crime.
