The subject matter is horrific but written with enough candour and sensitivity to capture the horrors and the minute hope of the Nazi Concentration Camp(s) in WWII.
You felt that much of the historical background was an an accurate portrayal of these horrifying events, which made the story more chilling.
He also did a commendable job in both portraying the different factions (Jew, Nazi, British, American) and captured the story in hand about Nazi Germany in WWII without ever being too gruesome or cloying.
Without giving too much away about the story it is told to us by a Rabbi, who describes the story to the son of the principal character.
The Rabbi tells the son that he must tell him the entire story, otherwise the end would not be believable.
The essence of the plot concerns persuading a German/Jew and an American Doctor/Scientist to join together to stop a Nazi poison gas attack against the D-Day Allied troops.
Their mission is to spread poison gas and kill all the prisoners of a concentration camp where the Germans were getting ready to give their high command, including Himmler no less, a demonstration of how effective nerve gas can be.
If successful and Hitler buys its effectiveness it is believed that he would sanction its use at the D-Day Landings.
You get to "meet" Winston Churchil early on and he intuitively fears the posibility that the Germans will use poison gas on the invasion of Normandy Beach and he mastermands this elite force to combat this threat.
The book details how lethal the nerve gases the Germans have developed such as Soman and Sarin which, BTW, was classsed as a "weapon of mass destruction".
The insidious nature of nerves gases, such as these, which are odourless and fast acting are absolutely horrific.
I'm a great fan of Greg Iles and have read most of his books but in the wrong order.
Not that it matters that much but this is very different to his later works which proves his versatility.
Whilst I thought it was an extremely good book I found the characters a bit one-dimensional and whilst I should have really engaged with them 100% found it difficult at times to do so.
It also got bogged towards the end and was somewhat confusing.
