The Becket Factor

Description for THE BECKET FACTOR by Michael David Anthony:

After years in government service, Richard Harrison is hoping for a quiet retirement in Canterbury, where he does volunteer work for the Cathedral and tends to his beloved disabled wife. Fate, though, has other plans for Harrison, which begin with a mysterious death, move on to blackmail in the secretive world of church politics, and explode into a media circus when workmen uncover a tomb that may be the final resting place of Thomas a Becket -- the notorious 12th-century Archbishop of Canterbury, otherwise known as St. Thomas. So much for that quiet retirement.
