Peter Davison stars as bespectacled, aristocratic private detective Albert Campion in this two-part adaptation of Margery Allingham's novel Mystery Mile. An American judge named Crowdy Lobbett (Brian Greene) has been targetted for extermination by a criminal organization known as "Simister" (clearly the villains are dangerous but illiterate). Heading from the US to England, Lobbett crosses the path of Campion, who offers his services. Before this case has reached its conclusion, our hero has been confronted with not one but two sudden and mysterious disappearances. In America, "{Mystery Mile" was telecast November 22 and 29, 1990, as part of the PBS anthology Mystery! ~ Hal Erickson, All Movie Guide
