Lord Rayle has been found murdered amongst his collection of medieval battle gear in Bowstring Castle. This is a locked room mystery of the first class. A fine puzzle to work and read through.
John Dickson Carr (or Carr Dickson) is very good at setting up a mystery puzzle. I was able to determine the murderer, and some of the method, but not all, even though the evidence was in front of me. However, the characters are not such that I feel any need to revisit this story. A satisfying, not enthralling read. ( )

Non-series mystery; detective is John Gaunt. Rater grim, not very like the often wildly funny Henry Merrivale mysteries Carr usually wrote as Carter Dickson. ( )
