In The Plot Thickens, Billy, a kind of private eye, is called in when crimes are being reported involving flat complexes.

He resolves to find out and make sure that the sergeant's faith in him does not go unwarranted. It is not so easy to find the evidence that he needs, but he is never one to give up. It appears that he needs to just find some more information.
