BEFORE PRIME SUSPECT THERE WAS TENNISON. Every legend has 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. When a photograph appears in the newspapers; showing Jane assisting the injured at the scene; it puts her and her family at risk from IRA retaliation. 'Good Friday' is the eagerly awaited date of the annual formal CID dinner; due to take place at St Ermin's Hotel. Hundreds of detectives and their wives will be there. It's the perfect target. As Jane arrives for the evening; she realises that she recognises the parking attendant as the bomber from Covent Garden. Can she convince her senior officers in time; or will another bomb destroy London's entire detective force? 'La Plante excels in her ability to pick out the surprising but plausible details that give her portrayal of everyday life in a police station a rare ring of authenticity' Sunday Telegraph
