The man in the crooked hat
(Book - Large Print)

Two years after Jack Pellum's beloved Olivia, a photographer, was strangled near the Huron River, Jack remains obsessed with finding the killer, whom he believes to be a man wearing a fedora he saw watching her a few days before her death. He continues to blanket the city with flyers bearing the suspect's image. Then Carl Dumisani, his former partner, reports that someone has written, "There's a killer, and he wears a crooked hat," on the wall near the body of a recent suicide. This news leads Jack to Paul Rook, who thinks that his mother was killed by Olivia's murderer.
