Given the below context:  Prominent criminal attorney Amos Strickland checks into the Lost Caverns Resort Hotel. His murdered body is later discovered by the bellboy, Freddie Phillips, who is implicated in the crime. Casey Edwards, the house detective, tries to clear Freddie, but Inspector Wellman and Sgt. Stone keep him in custody at his hotel room 'on the state'.  Strickland's secretary Gregory Millford and seven of Strickland's former clients happen to be at the resort, and they are all suspects. These former clients are Swami Talpur, Angela Gordon, Mrs. Hargreave, T. Hanley Brooks, Lawrence Crandall, Mrs. Grimsby and Mike Relia.  The bodies of Relia and the secretary Gregory Millford are found in Freddie's closet, and he and Casey try to move them and hide them.  The former clients gather for a meeting and decide that they must conceal their pasts and that Freddie must take the blame for the three murders. They trick Freddie into signing a confession, and then want him dead. Angela tries to seduce him, but the police stop her when they fear she's poisoned the champagne, then the Swami attempts to hypnotize him into committing suicide but his stupidity saves him.  Guess a valid title for it!
