The first, The Amethyst Box, gives title to the collection. The evening before his wedding a young man brings a collection of objects to the house party (why?) to amuse his friends, including a small amethyst box containing a tiny vial of poison. It seems a ridiculous action because, of course, it soon disappears following a sudden gasp uttered either by his fiancee or her best friend. When the aunt, an absolute ogre who raised both girls who are cousins, turns up dead the next morning it’s serious indeed. The second story, The House In The Mist, is a bizarre tale of revenge. The final story, The Ruby and The Caldron, is a puzzler as to what happened to a valuable ruby that disappeared between alighting from a coach and the front door when a startled horse created chaos.These stories are good examples of plotting because the brevity eliminates most of the melodrama found in many Anna Katherine Green novels. I recommend this book for those who enjoy early twentieth century mysteries.
