***SPOILERS*** A murder is committed at a hotel across the street from the dentist office that Mr. Logan is getting his teeth drilled. As he's about to go under or put to sleep Logan sees with his sharp eagle eyes the murder being committed and jumps out of his chair and rushes over to report it to the hotel manager where private investigator Mike Barnett,who's getting a drink at the bar, just happened to be who rushes up to the 5th floor to find out what happened. It doesn't take long to find out that there's no body but that's just half of the story. The other half is that it's later found out that someone was indeeds murdered there in room #505 but an hour before it was reported by Logan to have happened!
Barnett sniffing out a number of clues finds in the next room#504 this woman Gloria asleep or playing dead who in fact was at the scene of the murder who's terrified that the killer will do her in if she ever exposes him. In fact Barnett soon come to the conclusion that there's a major cover-up of the killing and the person who committed it forgot the time that he did it thus leaving a window of opportunity for the police as well as Barnett to catch him.
***SPOILERS***Pretty clever murder mystery that shows not only that crime or murder does s not pay but there's so such thing, unless one's well connected and with the right people from up high, as a perfect murder. It's the time line as well as the missing body, which was later found, in this baffling murder case that had Barnett pull all the loose ends together and finally find out who the killer is. That by the killer exposing himself by being so "concerned" in finding who the murderer was to not only solve or confuse the case but throw off the police and PI Barnett in trying to find him.
