I put off starting Tell No One by Harlan Coben because I could not finish the other one I checked out of library by same author. Tell No One was much better; page turning mystery to be solved.
Dr. Beck's remembers when his now deceased wife, Elizabeth did an internship, "She worked for Covenant House, rescuing runaway and homeless children from New York's worst streets," "sifting through putrid pols of quasi-humanity for children who needed shelter."
Another character did charity work, "helped street kids." One of those street kids he helped was arrested for murder.
