A Case of Exploding Mangoes

The book is a fictional account of the events leading up the real plane crash that killed Pakistan's president, Colonel Zia, in 1988.  At the core it is a story of revenge.  One of the narrators is a young silent drill commander in the air force, and the son of a former colonel in Zia's army who hung himself under questionable circumstances.  We learn early on that Ali Shigri has been training since he was a boy to kill the person responsible for his father's "suicide".  He just needs to find out who that person is.
