They Told me you were Dead by James Daniel

A story of revenge. The father of a subaltern who was killed by an IRA machinegun decides to take revenge by killing the killer in the same way. A rather roundabout story follows, sometimes clever, sometimes barely plausible. He almost succeeds, with the help of his brother-in-law, and all their ex-army contacts. A woman finishes the job.
