Erik Cohen is an elderly psychiatrist - but that was in 'Before Time'. Before the Nazi's sealed him, and countless others, into the Warsaw Ghetto. Now he lives with his niece, and grandnephew Adam, in a tiny apartment. It is 1940, freezing cold and life has been turned upside down. It seems to Erik that anything can happen, especially the worst. Then Adam goes missing and his body is found tossed on the barbed wire. It has been thrown there from outside the ghetto and his body has been mutilated. Stranger still, Erik finds a piece of string in his mouth and then discovers that other Jewish children have suffered the same fate. With his old friend Izzy, Erik sets off to discover who is luring Jewish children to their death and how, and why, Adam had left the Ghetto. This is a very atmospheric and exciting thriller, with great characters. Although the setting and situation is dark and dangerous, and the author portrays this with great tension and realism, the book also has humour and the spirit of humanity that nobody could take away from Erik and Izzy - who are great heroes indeed. I have never read anything by this author before, but I am sure I will be rectifying that. I read the kindle edition of this book, which was well edited and without typos. Highly recommended.
