The Confessors' Club: A PI mystery set in Chicago

An intriguing new mystery featuring Chicago private investigator Dek Elstrom
Men are dying in Chicago. Not ordinary men, but rich men, powerful men, men who control the city. They are being murdered, quietly, skilfully. Dek Elstrom’s ex-father-in-law, a major player in everything Chicago, is likely to be one of them. Amanda, Dek’s ex-wife, wants him to investigate.
Dek doesn’t want this case – but Amanda persists, and Dek finally agrees, because that’s what he always does with Amanda. He learns quickly that Amanda’s father is lying. The man knows plenty and is talking about none of it.
Is he about to become a victim? Or is he a killer?
