Move to Strike is the fourth book from Sydney Bauer - set in the US.
From the Blurb:
Doctor Jeffrey Logan, daytime TV's most loved psychologist, has a top-rating talk show seen around the world - his picture perfect life completed by his talented lawyer wife, Stephanie Tyler, their 16-year-old daughter, Chelsea, and 13-year-old son, J.T.
But this image of domestic bliss is shattered when Stephanie is killed instantly by a bullet from a big game rifle in the family's pristine Beacon Hill kitchen. The consequences of her death are catastrophic as Doctor Jeff confesses, despite all the evidence pointing directly towards his blood spattered son.
'Remind me why I am here again', said Boston Police Department's Homicide Unit Chief Joe Mannix as he tugged at the too tight bow tie around his neck.
