This 1958 ABC series, was filmed at AB Elstree Studios, two films being made per week. It was produced by the phenomenal Harry Alan Towers.
Tom Fallon, who had set up the 999 telephone emergency service, acted as adviser and
Robert Beatty had his finest moment starring as a Royal Canadian Mounted Police inspector, seconded to the British police. The series shows him gaining experience in the varied aspects of British policing.
"It will take me a long time to live down Mike Maguire," claimed Beatty in 1959. "The part hits me in the eye whenever I show my face.
I'm just waiting for a London bobby to tip his helmet instead of booking me for a parking offence." In a later interview he stated, with a slight exaggeration, that it "kept me out of television for about ten years."
Because Maguire worked alongside various police branches, he had no regular helper. These policemen however assisted him:
Duncan Lamont as Insp Winter (#1 The Killing Job), John Witty as Sgt West (#3 Illegal Entry),
John Warwick as Insp Blake (#9 77 Bus), John Howlett as Sgt Cole (#29 Deadly Blackmail), Richard Bebb as Inspector Pybus (#13 Special Branch)/ as Sgt Bellamy (#22 Barge Burglars): Richard told me he appeared in other stories too
