MERCY OR MERCENARY by Sheila Parker
This very English mystery revolves around the death of a distinguished biographer, Ralph Maguire. Maguire is in the terminal throes of dementia, and in his moments of lucidity he is trying finish his book about a celebrated actor.
When he is found dead, and the post mortem points to an overdose, the net of suspicion falls upon those around him, including his wife and those around him. The police investigation, led by Detective Inspector Kershaw uncovers family secrets as well as certain people who stand to gain by the biography remaining unpublished.
Mercy or Mercenary is published by Matador/Troubador and is out now.
