Seaweed Scare

As darkness falls, Vera goes to her room and is terrified by a cold, clammy touch on her neck. She screams, and the others rush to her aid. They discover that a wet ribbon of seaweed has been hung from the ceiling, which brushed against her throat. The scare is a psychological attack, designed to unnerve the group. The incident corresponds to the sixth line of the rhyme: 'A red herring swallowed one and then there were three.' The seaweed is a red herring, a distraction. The guests realize the killer is playing with their minds, using the nursery rhyme as a script.
