The British, American and Israeli Intelllgence agencies each have their own sometimes rather shameful reasons for tracing the identities of these nazis, although ostensibly cooperating with each other.

Apart from, a very good twist to the ending, there is a certain amount of comment on the theme of the rapidly evolving pace of world events.

But there is also some pathos and humour as well as analysis and action drama.
