The hapless Heine is trying very hard to be a good German spy in Great Britain during WWI but luck and circumstance are not with him. Every adventure turns out poorly for our dear spy. This collection of stories of Edgar Wallace about Heine was published during WWI and should be taken lightly by readers some may see it as a piece of anti-German propaganda, with Heine as a bit of a hopeless idiot. But the stories are also entertaining and should be read as such. Although these stories of German spy Heine are all linked and follow on from each other it is still very much a short story collection rather than a novel.
