Arthur Vernon, member of the Athenian club and member of "society," has a secret. His father has died and left him destitute, so he has begun a private investigation agency under the name "Nemo." It would be disastrous if this were known among his associates at the club, and especially if his intended in-laws found out. But he is quite sure no one else knows, that is until his old college classmate, Constantine Maunders, visits him with a proposition he can't refuse. Maunders knows all, and he wants to be made a partner in the agency, providing "Nemo" with black-mail worthy information on other people in society in return for a share of the financial rewards for their silence. Vernon is appalled, particularly as "Nemo" is engaged in solving a high profile blackmail case. These are the beginning of Vernons conundrums as the clues unfold. - Summary by Don W. Jenkins
