Many Mansions by Edward Bloor

Janice Richman, of the law firm MacDermott and Richman, locates Rowan Butler in the rural monastery he fled to twenty years prior as a bruised and shattered young man. Janice informs Rowan that his wealthy parents have died and left him a great fortune that includes mansions in Richmond, Charleston, and Savannah. Rowan takes off with Janice to begin a happy new life, but instead encounters family secrets, sinister threats, and a pair of bloody murders. It falls to Rowan to analyze the hidden clues, to deduce what the murders were really about, and to bring the killers to justice.
