I'm a fan of Richard North Patterson, and he can do so much better. Yes, I was drawn into the story and stuck with it until the (not-so-surprising) end, but now that I've finished it, I have the sense that he just mailed it in...and I feel like I need a shower.
This is the story of an estranged son, drawn back to his broken family due to the circumstances surrounding the death of his wealthy father. Was it a result of natural causes? Or was it an accident? Suicide? Murder? Have you read this one before?
Old relationships are revisited, reuniting the son with his mother, uncle, brother, and former lover, and introducing him to his father's recent mistress. While these characters are developed well enough, I just never found myself caring much about any of them...and if I'm not caring about the central characters in a work of fiction, I'm usually not going to be recommending it. This one gets two stars simply because I didn't abandon it altogether.
Patterson himself says in his notes that he always wanted to write a book based in Martha's Vineyard, and I think he simply came up with this little idea for a story, placed it in that locale, and stretched it into something that looks like a novel. I'll give him a mulligan, and hope that his next effort rises closer to the level of the books of his I enjoyed so much: Degree of Guilt, Eyes of a Child, and Protect and Defend, to name just a few.
