This is a comprehensive investigation by Chris Mullin into the Birmingham Pub Bombings on 21st November 1974. 21 people were killed and over 200 people injured when the IRA blew up two bombs, (one in each pub) in the city centre. The first pub was the Mulberry Bush and the Second was the Tavern in the Town, (later the Yard of Ale). It's very well researched, written and explains what happened prior to the bombings.
