I came cross this by accident in the superb Daunt bookshop in London's Fulham Road. I believe the owner was persuaded by a member of staff to republish it as it was out of print.
I could not put it down. It is set in Prague in WWII under Nazi occupation. The authorities notice that on the roof of a famous music hall there is a row of busts of great musicians and one is that of Mendelsohn, the 19th century composer, and, as he was a Jew, he has to go and go, he must, before the top Nazi (unnamed but based on Heydrich) visits the hall. The trouble is that the minions sent to get rid of Mendelsohn have no idea what he looked like and cannot decide which has to go. What ensues is a tale of men of no great intellect but who are rendered even more stupid by extreme orthodoxy allied to fear of criminal leaders - and only a great author can do that with a humour that moves and shows that from the darkest of times there is good.
The writer, Jiri Weil, survived the Holocaust by faking his death and going into hiding. He writes from experience, from history and with dark but human humour. The story moves at pace and is always interesting and I feel it is one of the best I have read in recent times, so much so I had to get his other novel of the time he survived, "Life with a Star".
