The Secret of Sigma Seven

by Franklin W. Dixon

Book 110 of the The Hardy Boys Mystery Stories series

Frank and Joe Hardy take on a case centered on a secret associated with Sigma Seven. The brothers must sort through a coded name, group, or project whose meaning someone wants protected, looking for the practical connection among clues that initially seem designed to confuse or frighten them. As the investigation grows more dangerous, teamwork and quick decisions become as important as identifying the person behind the scheme. Franklin W. Dixon’s Hardy Boys adventure combines conspiracy-style mystery with the series’ brisk juvenile-detective formula, using its distinctive premise to give Frank and Joe another fast-moving puzzle.
