Amos Posner, it's seems at the start of this story, needs clarity it's clear he is struggling to see through the foggy window of his life.
He was an international trader for years with a large firm but lost his position two years ago. He is married happily? maybe he's about to find out through dark days that follow his meeting with a woman.

His chance encounter on a bus with a attractive woman in a pink and white catapulted his life into a deadly spiral of seduction, deceit and deception.

There are characters in this story who have different religions and roots, their backgrounds do not hold importance in this mystery. The story is more of the psychological kind.

An interesting detective who steps on to the scene detective Wisdom, when Amos meets him he describes him as 'like that shrewd yet modest television detective Colombo, except he has neither a cigar not a raincoat."
I also liked the usage in this story of a particular drug that one character takes for a certain illness.

The story is not too long, it holds it's reader with I think just the right length.
This was a modest debut which had me picturing it as an old black and white movie adaptation unfolding, written by James M Cain.
Cain wrote wonderful noir stories not too long, psychology twists, murder and love involved. I would say this is the same quality but to have me think about that author of bygone days is something.
