Michael Prentiss is an agent with The Detachment.
According to the author's description:
"Prentiss is a sixteen year old young man attending the army’s selection centre to join the Royal Military Police. He is, however, recruited by a secret army intelligence unit known as The Detachment, or simply, ‘The Det’, for an unofficial operation in Londonderry. The Det’s role is to combat the Provisional IRA in Northern Ireland at the height of ‘The Troubles’.
"Michael Prentiss is a man born out of time. He believes passionately in chivalry, not as we know the word today, but in its truest sense of courage, bravery, honour and defending the innocent whatever the cost. Prentiss is one of three main characters in my books. Michael Prentiss, Colonel Charles Mabbitt, the CO of The Det, and Richard Jordan, one of its best operators. These are my three musketeers. Although all my books have rather intricate plots with many twists and turns, they are first and foremost character driven. I take the reader on a journey, following the lives of these three men and how their experiences change them, not always for the better."
