Only the shadow knows the truth

"X" is the story told in numerous parts.

The central part has Kinsey investigating a serial killer. She's unaware that as she gets closer to building enough evidence to nail the killer, she becomes a target.

The second layer of the story has Kinsey dealing with her landlord's elderly neighbors. At first they seem worthy of Kinsey's sympathy but there is something beneath their outer personae.

The final segment of the story is where the "X" comes from. It covers a woman of Greek heritage who recently divorced. She is still embittered about her husband's philandering when she discovers an art work in her husband's basement's basement that could be worth millions. But she has to smuggle it out of his basement to get it appraised in London.

The book is good but tends to jump from one story line to another too much. The characters are old friends by this 24th installment of Kinsey's actions.  I look forward to their antics but found the conclusion unfulfilling,  perhaps it was a prelude to a future story.
