Deadly Sins

Brant's careful research leads to believable twists and turns in her sixth Mindhunters romantic FBI procedural. When a Supreme Court justice is gunned down, his widow asks former FBI agent Adam Raiker, owner of Raiker Forensics, to serve on the special investigative task force with Jaid Marlow, whom Adam was involved with eight years earlier. A note from the killer links the judge's murder to another unsolved case, but as Adam and Jaid connect the dots, the killer takes aim at Adam. The well-paced thriller reveals multiple victims and minor conspirators but cleverly conceals the mastermind's identity, and Adam and Jaid slowly move past regrets and mistrust to rebuild their relationship. Abundant subplots and characters from earlier volumes sometimes confuse the reader, but Brant does a credible job of tying all the loose ends together. (Aug.)
