More than one case of mistaken identity is leading an expatriate Briton into hot water in Greece in this tale of suspense. Harry Barnett (John Thaw) was once a successful British businessman, but after his luck and his business acumen went south, Harry suddenly found himself single, and these days he works as a laborer for his old friend Alan Dysart (Matthew Marsh), a former government figure who fled to the Greek island of Rhodes to get away from a scandal. One night, Harry enjoys a brief fling with Heather Mallender, an attractive woman from out of town; the next morning, Harry discovers that Heather is nowhere to be found, and has seemingly disappeared. When Dysart's men seem downright casual about Heather's death, it draws Harry's suspicion; he begins digging, and learns Heather's death parroted the killing of one of Dysart's former employees -- who was also Heather's sister. 1997's Into the Blue was originally produced for British television, and first aired in the United States as part of the anthology series Masterpiece Theatre.
