It's a treat to be led by the nose by a good mystery writer. Most of what CDI Macdonald knows by the end of the book is also known by us, the readers, but we are helpless in the hands of this author. When the truth is revealed at the end, we slap our foreheads and say "Of course, why didn't I see that before?"
The outline of the story is of the murder of a blackmailer by hit-and-run, using a stolen car. The car belongs to a political bigwig who is about to be appointed to a big office, and the blackmailer appears to have been collecting evidence to blackmail the bigwig. Did the bigwig do it? Was it a setup from his political enemies? Was it an unbelievable coincidence? It's all there for you to put together. Go and test your mettle against the redoubtable Chief Detective Inspector Macdonald.
One can't give an honest review of this book, written in 1939, without talking about the elephant in the room -- its discussion and treatment of Jews. One of the suspects is a big financier, very cultured, and a Jew. His portrayal is a stereotype, not a hideous one by any means, but still given abilities and qualities that are closely associated specifically with rich Jews in the minds of many people. Another, very sympathetic, character is irrationally afraid of the influence of Jews on his country -- these days we would call that anti-Semitism. And worst of all is that even CDI Macdonald says the following, in a discussion with a British elder statesman:
"Isn't that the crux of the whole Jewish problem?" asked Macdonald. "That in their national cleverness they always try to go one better than the Gentile? Have they not brought much of the present trouble upon their own heads by being too clever?"
It is clear from the contents of the book that, although the author knew of such things as labor camps and Jews fleeing from parts of Europe for their lives, she did not know of the "final solution" nor of the death camps. Still, this is one of the most vile sentiments I have read from that period, from a supposed neutral voice of a Scotland Yard CDI.
Many books we read that were written in earlier periods have new prefaces in them, warning the reader of such very uncomfortable content, and avowing that they are keeping the text intact for historical reasons. These prefaces at least acknowledge that this kind of by-the-way prejudice has no place in modern literature. These new electronic editions of Lorac's works are clearly not being even proof-read -- there are many obvious OCR errors that are not corrected -- and no-one has bothered reviewing the content. So be alerted here to this very uncomfortable content.
