Silence 

Edgar-winner Perry (Pursuit ) delivers another intelligent, literate thriller. Jack Till, a retired LAPD detective turned PI, has settled into a somewhat monastic existence, at the center of which is his 21-year-old daughter, Holly, who has Down syndrome. Six years earlier, Till helped restaurateur Wendy Harper escape from would-be assailants. Showing her the techniques the police use to track down fugitives, Till taught the woman to assume a new identity and begin a new life. When Harper disappeared, many assumed she was murdered. Now, years later, someone is trying to frame Eric Fuller, Harper’s business partner and sometime boyfriend, for her murder. The only way for Till to prove Fuller’s innocence is to produce Harper in the flesh, but first he has to find her and persuade her to come back while evading assassins Paul and Sylvie Turner, who have been hired to kill Harper when she resurfaces. As always, Perry excels at the procedural details, keeps up the pace throughout and will have readers guessing until the end. Author tour.
