CANNON? "One of the most critically acclaimed television series from the 1970s", as the jacket says??... I mean, it was a successful private eye show, yes, but...
Perhaps they confused it with Barnaby Jones! After all, Cannon did turn up in Barnaby Jones.
I’ve got a lovely little private eye show called Public Eye (ABC/Thames 1965-75), created by Roger Marshall and Anthony Marriott) which did seven series. Frank Marker (Alfred Burke) used to investigate the sorts of things that down-to-earth enquiry agents usually tend to. He also needed to take just about every case that crossed his path, because he needed the money. He took a few beatings and got thrown into the River Thames. There was an internal continuity going. He went from London and moved to Birmingham for a while. Marker gets jailed at the end of the third series series and spends a year in prison. He then moves to Brighton (with a slower-paced theme) and Stephanie Beacham stops by, during a period where he tries to get going again after his release.
The Brighton titles also open series five but then he moves again to Windsor, so there is another title sequence change from episode two and back to the regular title music and the show goes colour. Marker also spends time recuperating after another vicious beating and gets involved in a private eye partnership for a while before moving again to Chertsey. In his last case, however, he is in with a chance of earning a large fee for once. He misses it by 15 minutes. It was very successful but Alfred Burke bailed on doing more episodes because Euston Films were going to shoot it and he had reservations about how that might affect the show.
