Career
Journalism
Hallworth worked as a crime reporter for the Daily Mail. He reported on many cases but most famously on that of suspected serial killer Doctor John Bodkin Adams in 1956. Both times Hallworth was given a dressing-down but no more.
Hallworth later co-wrote a book about the case, published in 1983 after Adams" death.
In it he accused the prosecuting counsel of mismanaging the case, saying that Adams, who was acquitted, was in fact a murderer. However, Hoskins carried on in his position and Hallworth was left to "wither on the vine".
Publicity
Hallworth eventually left the Daily Express to become a publicist, representing amongst others, notorious yachtsman Donald Crowhurst in 1968-1969. Crowhurst disappeared in the Caribbean during a round-the-world yacht race and Hallworth flew over to collect his boat"s logbooks, which he then sold to the Times newspaper for "a small fortune".
Hallworth"s part in the affair brought him a lot of criticism, leading him to being called "money-grubbing" and "unscrupulous".
According to others who knew him, however, Hallworth was a "genial, rotund chap" who was "larger than life".
