DI Frost welcomes a new member of the CID team, PC Ronnie Lonnegan. They soon are investigating a mysterious death when a body is found in the local water reservoir. There is no identification on the body and there doesn't seem to be a car parked nearby so they're not sure how he got there. The post-mortem indicates however that he didn't drown in the place where his body was found. They also investigate the death of Paul and Jean Harris who are killed when an an assailant ties them up and sets their house on fire. The main suspect is Mike Patterson, a handyman who had been doing work for the couple and who may have also been having an affair with Jean. Forensics indicate there is a connection between the death of the unknown man and the Harrises. Meanwhile, Supt. Mullett is his usual concerned self about a formal inspection of the station by a senior officer. Frost is also his usual self, which doesn't help matters. Written by garykmcd

Great drama!
13 December 2006 | by jamiecostelo58See all my reviews

Jack attends a seminar and gets rather friendly with attractive profiler and counsellor Pam Hartley. He's also teamed up with Ronnie Lonnegan, but they get off to a bad (but amusing) start! There could be a psychotic killer on the loose in Denton, and Jack has his work cut out. We also see the return of a character whom we have not seen for eight years!

Cue the usual gaffes (one involving ice-cream vans!) and serious drama, and this two-part edition proves another winner with viewers. Mistaken Identity was the final of three two-part specials of A Touch of Frost, and part one is hugely enjoyable.
