Accountant Anthony Costello has a talent for manipulating both numbers and people, turning losses into profits, enemies into allies--and vice versa. When Costello is found murdered in his own home, three suspects had motive. All three had access to his home. And all three women are missing. Are they in the wind--or in the grave?

Eyes are on Detective Sean Walsh, whose personal connection to the case is stronger than leads to solve it. Neither the powerful bankroll behind Costello nor Walsh's vengeful superior officer can budge the investigation, yet as Walsh continues to dig, he uncovers even more reasons the women have to stay hidden--from the law, and from each other.
