Role in And Then There Were None
Despite knowing that Cyril wasn't a strong child, Vera let him swim far out into the sea. The intent was that he would drown, so that Hugo would inherit money and thus propose to Vera.

The inquest declared Cyril's death as accidental, however Hugo realized Vera had sent Cyril to death and left her. Hugo later told the story to Lawrence Wargrave.

Cyril drowned on August 11, 1935.
