Good Friday

Before Prime Suspect there was Tennison and every legend has to have a beginning . . .

During 1974 and 1975 the IRA subjected London to a terrifying bombing campaign. In one day alone, they planted seven bombs at locations across central London. Some were defused - some were not.

Jane Tennison is now a fully-fledged detective. On the way to court one morning, Jane passes through Covent Garden Underground station and is caught up in a bomb blast that leaves several people dead, and many horribly injured. Jane is a key witness, but is adamant that she can't identify the bomber.
