Inspector Jake Fraser is about to have yet another busy month.
A man's body is found in a tenement flat. Women have been going missing off the streets of Aberdeen. Members of the Business Club appear to enjoy the protection of each other's silence leading to secrets being kept behind the ornate front door.
Jake is already trying to bring the murderer of Mabel Lassiter to justice and now he must try to uncover some of those secrets if he is to prove that there really are more answers than questions to be found within the walls of the Business Club.
What Jake does not realise, however, is that there are other, less obvious, secrets to be uncovered in the course of his investigation.
But those secrets may only further complicate an already complicated investigation.
