One of my personal Reading Challenges this year is to read as many of the British Library Crime Classics as possible and this is the first I have finished. It was a great start because I really enjoyed the book, both in terms of the mystery and the historical background; it was originally published in 1945 and it is set in that period. I did not attempt to guess the solution to the crime which is probably as well because I imagine the motive as finally revealed would probably have resonated far more with people at the time than it does in our very different time
